PERFORMANCE TEST:

It is imperative to accurately measure the transom mount height for an Epropulsion outboard. Having the wrong measurement for the shaft length can drastically affect the performance of the outboard. If the measurement taken is too short for the transom mount, the propeller will not sit deep enough in the water. When the propeller does not sit deep enough in the water it will cavitate and decrease efficiency. If the measurement taken is too long for the transom mount, the propeller will sit too deep into the water. When a propeller sits too low behind a boat, it will have increased water resistance and reduced speeds.

How to Find Your Shaft Length

If you are looking for an ePropulsion electric outboard for your boat, choosing the correct shaft length is important. 

Please note that ePropulsion has a different shaft length measurement from gas-powered outboards. For electric outboards, the shaft length is measured from the top of the clamp bracket to the center of the propeller. For gas outboards, it’s measured from the top of the clamp bracket to the anti-ventilation plate.

As you can see, our XS is close to S from Mercury. Our S is close to L from Mercury. Our L is longer than L from Mercury. See below.

To find the suitable shaft length, the principle is to make sure the top of the propeller is matched to the lowest point of the transom. Hard to put it into practice? Well, in order to get the right shaft length, first, measure the transom height, the length from the top of the boat transom to the bottom of the boat.

After that, you could choose the recommended shaft length based according to the transom height.

For most small dinghies and aluminum boats under 15ft or 4.5m, extra short shaft and short will work, depending on the transom height, some over 40 cm / 15.7 inches, some not.

For boats with the transom height higher than 50 cm / 19.7 inches, a long shaft version is more suitable.  For daysailers, sports boats and other sailing boats it’s best to measure the distance from the water line to the top of your outboard mount.

Customer Reviews

I purchased an EPropulsion motor from TBN. Ryan and Chris were superb helping me choose the right one. I’m very satisfied and appreciate their responsiveness, friendliness, and professionalism.

Perfect setup for my ship to shore needs. Well built, silent and quite powerful. TBN was excellent vendor, great communication and items shipped quickly.

The motor is quiet and works great the only thing is the battery lifts about 1/2 inch when tilting.

Used it on finger lakes ny recently on my Bauer 12 sailboat 330 lb plus 2 adults. Motored easily at 4 knots. Quite and smooth. Wife acceptance factor very high. Happy with the purchase. Staff very helpful and responsive.

ePropulsion Spirit 1.0 Plus: Electric Outboard Field Test

Advertisement

Our contributing editor has used his new low-power electric outboard, with its dedicated carry-on battery, for two years now, and it looks like we have a convert!

With an electric outboard, the loudest thing you’ll hear is water lapping against the hull, the only emissions will come from you, humming as you enjoy the tranquility.

Count me among the original naysayers. During three decades of immersion in the marine industry, every new electric outboard I saw smacked of not-ready-for-primetime prototyping, fanciful claims, and marketing doubletalk. Meanwhile, my own hydrocarbon-chugging outboards propelled me across the surface of the water with ever-improving reliability and ease of use. Me? Become a believer in voltage-delivered velocity in an outboard motor form? Unlikely.

Then, for professional purposes, one day I clamped a 3-hp ePropulsion Spirit 1.0 Plus to the transom of my small fishing boat. In comparison to the old-tech electric trolling motor I'd been using on area lakes and ponds that prohibit gas, my speed doubled, my range quadrupled, and the weight of the old rig was shaved in half. It hit me that those tree-hugging electric lovers might be onto something.

Electric motors have been in use on boats since the 1880s when French engineer Gustave Trouve patented his first paddlewheel rig. As early as 1973, Ray Electric Outboards proved that you could design an electric power plant that clamped to the transom like any other outboard motor. Yet they've remained an exceptionally poor alternative to internal combustion due to one simple limiting factor: the ability to store enough "fuel"; (batteries) aboard the boat. And while plenty of manufacturers have developed electric outboards, they left the battery "solution"; up to the consumer, often with little or no advice as to just what that solution consisted of.

These LiFePO4 cathodes last longer and, according to the manufacturer, live through around four times as many discharges and charges than the older lead-acid batteries. Critically, some electric outboard manufacturers have begun designing these batteries specifically for their motors.

Net result? With a 3-hp model hitched to the transom of a jon boat or dinghy, in my experience with the ePropulsion Spirit 1.0 Plus, you can see speeds of around 5 mph and a range in the vicinity of 15 to 20 miles. The outboard actually looks like an outboard, and popping off the "powerhead"; makes for easy portability and charging.

Price is something of an issue with small, portable outboards . The ePropulsion goes for around $2,500 and the Torqeedo MSRP is $2,948. You can pick up a similarly sized gasoline eggbeater for more like $1,200. Then again, you'll also have to suffer through the noise, vibrations, and fumes that go along with internal combustion.

Other manufacturers are getting on board. During a visit to Lake X, Mercury's secret testing grounds in Florida, I got a first-hand look at the Mercury Avator electric outboard concept. Mercury's entry into the electric propulsion category incorporates a cowl-like compartment styled like their other outboards that has a door that swings open to accept a drop-in battery. No performance info is yet available. But, importantly, Mercury plans to provide dedicated, portable, quick-charging batteries to power the Avator.

Mercury Avator Electric Outboard Concept - SNEAK PEEK!

The Takeaway

I've used my ePropulsion Spirit 1.0 Plus for more than two years now, and the extended range, increased speed, and reduced weight make it a far better option than the traditional trolling motor options I've used in the past. A gasoline outboard would certainly provide better range, but who needs to go more than 15 miles on small lakes and ponds on a 12-foot fishing boat?

Once you turn the tiller on one of these little electric outboards, you'll never want to yank on a starter cord and listen to the racket of internal combustion again.

One worry might be that the manufacturer decides to update the model (or goes out of business), and replacing the battery could become an issue — a problem many of us have experienced with electric power tools and similar items through the years. Time will tell, but that's a risk we take with many products. If you're in the market for one of these outboards, be sure to buy from a name-brand manufacturer that has some proven history.

Epropulsion Spirit 1.0 Evo: the power of silence

One of the most extensively used equipment on board is the outboard engine , which, together with the tender, represents a sort of link with the shore, an umbilical cord capable of getting us to the beaches and coastlines we want to discover effortlessly and safely. We may not think about it, but if our engine breaks down or our dinghy has a puncture, the feeling is of confinement, because we can’t go ashore.

EPropulsion Spirit 1.0 Evo Test

We’ll be testing this new engine for two or three years. According to the specifications given by Marco Esposito, the engine already looks extremely interesting. The Daydreamer , our editorial staff’s Comet 460 , is equipped with a Selva 320 Vib tender, with a not too heavy inflatable keel fitted until now with a Selva 2.5 HP Guppy.

Without battery, the engine body is very lightweight and easy to handle ( total weight, including battery, is 20 kg ). The outboard is availble in three different drive sizes: 30-40 cm, 40-50 cm and over 50 cm. The bracket for attachment to the tender consists of two levers with screws, with the possibility of fitting a safety lock. Finally, the engine is assembled on the tender, we can’t wait to see how it works.

EPropulsion Spirit 1.0 Evo operation

We climb on board the tender , with the electronic transponder in our hands. A special magnetic slot accepts it in one place, the control electronics recognize it and enable the system. It works as an anti-theft device but also, of course, as a security lanyard, like the red ones which we are used to. One press on the On/Off button and the digital monitor switches on.

Now let’s find out what the digital monitor is telling us. First of all, on the top left, there is a bar with sectors that graphically indicates the battery charge status. Next to it is an indication of the remaining charging volts, the maximum cell voltage being 39 volts. Another fundamental piece of information provided by the monitor is the remaining operating time, i.e. the autonomy in terms of minutes that the engine can guarantee at a given speed.

As you would expect, of course, the more power we ask for, the less range we will have: exactly as with internal combustion engines. However, we also discover a huge difference between a slow pace and a fast one. After all, for a small increase in speed, we really do sacrifice a lot of energy, but why do we have to run? What’s the hurry? The manufacturer claims that the maximum range is 80 miles, about 36 hours at minimum power, and 8 miles, just over 1 hour, at maximum power.

For example, in Villasimius we stayed at anchor, about 1 mile from the landing pier of the marina, three times in one day we went there and back in 4 people, for a total of 6 miles: fuel consumption, at medium/high speed, was 60% of the battery. With 40% remaining, it would be possible to sail for another 3 or 4 hours, using the motor at around 300 W.

The battery, with a capacity of 1276 Wh , makes use of the latest lithium polymer technology. Recharging is done via the standard charger, 8.5 hours for a full charge, but in normal everyday use it takes just over an hour to bring the charge to full. But there is a secret that makes this motor truly magical, let’s find out.

Energy hydrogenation

Yes, the batteries of the Epropulsion 1.0 Evo can recharge themselves , or rather, without any effort on our part and without consuming precious energy. It is sufficient to leave the engine mounted on the tender when we drag it around (it is better to secure the fastening levers with a padlock, just in case), the flow of water pushes the propeller blades, the engine turns and produces energy by recharging the batteries. That’s the egg of Columbus: if the boat slows down almost nothing, whether sailing or motoring, we find ourselves at the end of the transfer with the battery at full power.

During our cruise we measured about 1 notch of charge every hour/hour and a half of sailing at 6 knots, plus the tender sailed nice and straight with no jolts or jerks. It is well known that, on sailboats, energy is precious and should not be wasted: an hydrogen system can brilliantly and completely solve the problem of recharging. From the tables provided by the manufacturer, we can see that at 6 knots energy generation is 100 W, while at 8 knots it is already 200. Its maximum is 330 at just over 10 knots when it goes into protection and limitation.

EPropulsion Spirit 1.0 Evo: c onclusion

The EPropulsion Spirit 1.0 Evo we extensively used during our long cruise proved to be a good alternative to traditional petrol outboards of equal power, with the same performance, better manageable, lighter, more practical, quieter, not at all “smelly” and more ecological. It represents the beginning of an epoch-making change in mentality and habits, of a contribution, albeit minimal, to the safeguarding of the planet, because it seems to bring the world of motorboating closer to that of sailing and we, who deeply love the sea, are very happy about all this.

Electric outboard motor: we test 13 options

• July 25, 2023

An electric outboard motor is now a viable option for dinghy propulsion. Emrhys Barrell puts the latest outboards and trolling motors to the test

The electric outboard motor has been around for many years, but they have either been too low powered or their lead acid batteries have made them too heavy to lift in and out of a small tender, so petrol outboards have remained the engine of choice.

The development of lightweight lithium batteries has changed all this, making an electric outboard motor a practical alternative to petrol – and making all electric yachts a real possibility too.

With this in mind, we tested 12 models whose all-up weight, or the weight of their individual components, did not exceed the 14-17kg of a 2.5hp petrol outboard.

See how we tested the electric outboards at the end of this article.

Best electric outboard motor

Specifications Outboard weight:   12kg Overall weight with outboard and bracket: 14.5kg Battery capacity: 1085Wh Top speed: 5kts Thrust: 30kg / 66lbs

Designed along the lines of a dinghy rudder, this Remigo outboard is incredibly easy and intuitive to use. No external cables or anything to be snagged, it clips onto a bracket pre-mounted to your tender or dinghy, in a similar way that you’d attach a  dinghy rudder.

Flip down the handle, attach the magnetic kill cord and you’re good to go.

On test this outboard gave as much thrust as the ePropulsion below but out performed it in terms of maneuverability. The Remigo can be switched from forward to reverse thrust at the touch of a button.

We like the Remigo for it’s sleek simplicity. If you want a clean smart easy to carry outboard to take you from your mooring to shore or quietly meander from your anchorage to shore then this is definitely worth considering.

We especially liked the rudder effect of this outboard giving us steerage even we had turn the power completely off to coast in alongside our pontoon.

ePropolsion Spirit 1.0 EVO

Yachting Monthly’s best buy

Specifications Motor weight:   10.5kg Battery weight: 9kg Battery capacity: 1276Wh Top speed RIB: 4.5mph Top speed skiff: 6.0mph Thrust: 31kg/68lbs

The Chinese firm ePropulsion has been developing its electric outboard motor range and lithium batteries for some time. We tested the Spirit 1.0 Plus and Evo, both 1kW motors with integral batteries.

Clearly ePropulsion was influenced by Torqeedo, but there are some important differences. From the outset ePropulsion went for a direct drive motor, being quieter and avoiding gearbox problems.

The battery has a greater capacity than the original Torqeedo, and is still 30% higher than the latest version. It also floats – useful if you should drop it overboard.

Fitting the battery is a two-handed job, with the carrying handle being at the back, and latch lock at the front, which requires leaning over the transom to install it. You also cannot see the locating slots underneath, which isn’t quite so easy in a bobbing inflatable. The power cable socket is protected by a rubber cap.

You have a display, but it only shows power being consumed, voltage, and remaining runtime, which means it has larger figures, easier to read on a sunny day, but it lacks GPS speed or range.

It has the same trim settings as the Torqeedo, with a similar fiddly retaining split ring. It also has a magnetic kill cord. Three shaft lengths are available, catering for transom heights up to 61cm. The shaft is streamlined but rotates through 360º for maximum manoeuvrability and reverse.

Yachting Monthly’s best in class

Specifications Motor weight:   10.5kg Battery weight: 9kg Battery capacity: 1276Wh Top speed RIB: 4.5mph Top speed skiff: 6.0mph Thrust: 68lbs Regeneration: 4 knots – 40W / 10 knots – 300W

The 1.0 EVO has the same dimensions and performance as the Spirit, but it has the options of a removable tiller, plus remote controls and steering, but the real innovation is that it offers regenerative charging while you are sailing, putting 40W at 4 knots, and 300W at 10 knots back into the battery.

You can even have a wristband remote for steering and throttle.

The ePropulsion Spirit 1.0 EVO is undeniably more expensive than it’s little sister without the regenerative charging and the cost difference is significant. If you are likely to be doing a lot of sailing and using your electric motor from ship-to-shore in relatively remote locations then the regeneration will probably be worth it. For most, though the price differential is probably a little too steep.

Torqeedo 1103 and Torqeedo 603

Torqeedo 603 specifications Motor weight:  11kg Battery weight:  4.2kg (floats) Battery capacity: 500Wh Top speed RIB: 4.0 mph Top speed skiff: Not tested Thrust: 44lbs

Torqeedo 1103 specifications Motor weight:  11kg Battery weight:  6kg Battery capacity: 915Wh Top speed RIB: 4.4mph Top speed skiff: 6.0mph Thrust: 68lbs

Torqeedo was the first company to commercially produce an outboard with an integral lithium battery in 2005. The earliest motors used a high-revving geared motor, which produced a characteristic whine. Following the launch of its new larger battery, Torqeedo changed to direct drive at about the same time that ePropulsion arrived on the scene.

The 1103 is 1.1kW and has a removable battery and tiller/throttle. The battery locates in slots in the powerhead and can be dropped in one-handed, with the slots clearly visible from above, which is helpful in a rocking dinghy. It then hinges back and locks in place with a separate plastic pin. The tiller locates in similar slots.

The two are then connected to the motor by a power cable and a data cable, but the latter has an 8mm plug, with five tiny pins that have to be carefully lined up, then secured with a threaded plastic collar. Neither of the sockets have caps to prevent debris or water getting into them when the cables are not connected.

The display on the tiller shows four lines of data at the same time, which makes them small to read (a phone app can be used for a large display). They include volts, battery capacity, range at a given speed, speed in kts, mph or km/h, and power consumption in watts. A magnetic kill-cord cuts the power circuits if you fall overboard.

The motor has four trim positions to allow for angled transoms, but the split ring securing the locking pin is very stiff and fiddly, especially when you have to adjust it hanging over the transom. A side-mounted lever allows the motor to be tilted horizontally. In normal use a catch prevents the motor kicking up in reverse, but this can be released with another side-mounted lever if you are in shallow water.

Long and short shaft versions are available, with the height of the transom to the top of the prop on the long shaft being 62cm. Clamps screws and fittings are stainless steel, making it suitable for salt water use, but an anode is an extra. It has forward and reverse but not 360º rotation.

Haswing Ultima 3

Specifications Motor weight: 11kg Battery weight: 5kg Battery capacity: 600Wh Top speed: RIB 4.0mph Top speed skiff: Not tested Thrust: 51lbs

Haswing is a new name to us, but this Chinese manufacturer now has an extensive range of motors, several of which we were able to bring along to our test.

The Ultima 3 has an integral Lithium battery and an output of 1,000W, with the ‘3’ in its name indicating the 3hp petrol outboard its makers claim it is equivalent to. The battery is 600Wh.

The battery was the easiest of all in our test to fit and remove, just sliding down a set of grooves, with contacts in the bottom removing the need for any linking cables or wires, and an easy one-handed operation.

The unit is well engineered, with stainless steel used throughout plus an anode as standard, making this suitable for use in salt water, and a spare anode and shear pin. The tiller/throttle hinges up and down for easy operation and storage. It has a streamlined aluminium leg, but rotates 360º.

A magnetic kill cord is a useful safety feature, and there are 5 LEDs showing battery capacity remaining, but this is the only instrumentation, so there is no way of gauging how much power you are using. It also meant that with no exposed power cables, we could not measure intermediate power settings.

Motorguide Varimax 40

Specifications Motor weight:  9.1kg Battery (Sterling 60Ah) – 8kg Battery capacity: 780Wh Top speed RIB: 3.2mph Top speed skiff: 4.0mph Thrust: 28lbs

Another trolling motor, this has a claimed 40lb thrust and a variable speed electronic control. The throttle pulls forward for ahead, and pushes back for reverse then twists in the same direction for speed. A clever feature once you get used to it. Ten LEDs show the battery state.

The sliding shaft gives transom heights up to 65cm transom to prop, and 360º rotation. It also quickly tilts through 90º, with 5 positions, for shallow or weedy water.

Clamp screws and fittings are mild steel, meaning you should wash it off with freshwater after using it in the sea.

Clever throttle control Variable transom heights accomodated

Quite basic in functionality

Haswing Osapian 55

Yachting Monthly’s best budget buy

Specifications Motor weight:  9kg Battery weight:  (Sterling 60Ah) 8kg Battery capacity: 780Wh Top speed RIB: 3.3mph Top speed skiff: 4.4mph Thrust: 35lbs

This is another trolling motor with a claimed 55lb thrust, but with five forward speeds and three reverse on a twist-grip throttle. Again, it is a well-engineered motor, with all fittings and clamp screws made of stainless steel, an anode behind the prop and a spare in the box.

Five LEDs show the battery state. The sliding shaft gives transom heights up to 62cm, and 10 tilt positions.

As with all click-speed throttles you have double the power at Setting 5 compared to Setting 4, and very poor range figures at intermediate speeds compared to motors with electronic throttles.

However it is an excellent value-for- money option for sailors looking for ways to power their tender for short trip

Well engineered Value for money

Poor range at medium speeds

Motorguide SW82

Specifications Motor weight: 13kg Battery weight: 16kg Battery capacity: 1,560Wh Top speed RIB: 4.0mph Top speed skiff: 5.5mph

Motorguide is a well-established US company that is part of the Mercury/Mariner group. The most powerful of the transom mount range, the 82 has a claimed thrust of 82lbs, and is a 24V unit requiring two 12V batteries in series.

It is also designed for saltwater use, with stainless steel clamp screws and fittings, and a large anode on the shaft. It has an extra long shaft, giving up to 93cm transom height to the prop, 360º rotation, and seven tilt positions There are no battery LEDs. An on/off switch under the control head is the nearest it gets to a kill switch.

Well known company Powerful Anode for salt water

No battery LEDs

Haswing Protruar 1

Specifications Motor weight: 9kg Battery weight: 8kg Battery capacity: 780Wh Top speed RIB: 3.4mph Top speed skiff: 4.5mph Thrust: 40lbs

Another Haswing requiring a separate 12V battery, this has a variable speed electronic throttle, and similar features to the Protruar 5, except no kill cord. It claims to be equivalent to a 1hp petrol motor, but in practice delivered 600W.

The sliding shaft only allows transom heights up to 40cm, but a longer shaft version is available. It has 10 tilt positions and 360º rotation.

Another well engineered unit, with stainless steel used throughout plus an anode as standard, and a spare anode and shear pin. The tiller/throttle hinges up and down for easy operation and storage.

Anode for salt water use 360º rotation

Haswing Protruar 5

Specifications Motor weight: 14kg Battery weight: 16kg Battery capacity: 1,560Wh Top speed RIB: Not tested Top speed skiff: 6.1mph Thrust: 108lbs

Another Haswing, the Protruar 5 is the most powerful model we tested. The unit is extremely well engineered, with stainless steel used throughout for the clamp screws and fittings, plus an anode as standard, making this suitable for use in salt water. A nice touch is the spare anode and shear pin in the kit. The tiller/throttle hinges up and down for easy operation and storage.

Its 5 designation indicates its makers think it is equivalent to a 5hp petrol motor, but in reality it delivers around 2.5kW at 24V so requires two separate batteries. It has a variable electronic throttle, three battery state LEDS and a magnetic kill cord.

The shaft slides up and down, giving a maximum transom height of 62cm and 360º rotation. Ten tilt positions are quickly engaged by a squeeze lever.

The thrust was the highest of the test, making it suitable for heavy boats, but the fine pitch prop significantly reduced its efficiency at speed.

Motorguide R3 45

Specifications Motor weight:   9.5kg Battery weight: (Sterling 60Ah) 8kg Battery capacity: 780Wh Top speed RIB: not tested Top speed skiff: 4.1mph

This trolling motor has a claimed thrust of 45lbs and five forward speeds. The sliding shaft gives transom heights up to 65cm and 360º rotation, with seven tilt positions. Clamp screws and fittings are mild steel, so should be washed after saltwater use.

The click-speed throttle gives non-linear power gaps, with Speed Setting 5 being double the power of Setting 4. This throttle arrangement results in poor range figures at medium speeds compared to motors with electronic throttles, but it keeps the price down.

360º rotation Plenty of transom height range

Minn Kota Endura Max 55

Specifications Motor weight: 9.5kg Battery weight: (Sterling 60Ah) 8kg Battery capacity: 780Wh Top speed skiff: 4.6mph

Minn Kota is one of the oldest makers of trolling motors. The Max 55 has a claimed 55lb thrust, with a variable speed electronic twist-grip throttle.

Clamp screws and fittings are mild steel, making it best suited for freshwater, though you can use it in the sea if you wash it off afterwards.

It has a fine pitch prop like all trolling motors, which gives a good static thrust, but efficiency, and hence range, falls off at higher speeds, though the electronic Maximiser throttle helps to offset this.

How we tested the electric outboard motors

We took a selection of electric outboard motor units available on the market, and tested them in two situations, firstly on a Frib 275 folding RIB on the Lymington River to reproduce the situation of getting out to your boat in the tender. We then put them on a 4m skiff on the Thames, to see how they perform at higher speeds on a boat with a smoother underwater form and longer waterline on sheltered waters.

Speed: We measured speed using a handheld GPS, and electricity consumed using a clamp ammeter or the motor’s inbuilt power display. We converted these to the range you would achieve, either for a given power, or the full power of the motor’s battery.

Thrust: We measured static thrust using a spring balance. This is a somewhat crude test, as it measures the pulling power of a motor in a static boat, and therefore doesn’t allow the propeller pitch to work at its designed speed.

Function: We checked the stated weights of each of the motors and made a qualitative survey of their main features when used as a dinghy outboard.

We tested the trolling motors with a 60Ah lithium battery from Sterling Power, which cost £360, though you can use a heavier lead acid battery costing around £120 for a good quality AGM or gel. Don’t bother with leisure batteries, which will fail after 4 to 5 trips. You will need a good quality Lithium charger, which will add on £100 or more.

We haven’t included charging in this test, as this is dependent on the charger you are using, whether you are charging from 240V or 12V on board, and whether the power source is mains, a generator, alternator or solar. It’s worth noting that you will rarely be recharging from flat, and will rather be aiming to top up batteries after each use.

Trolling motor or electric outboard motor?

The options today are trolling motors with separate batteries – so called because they were mainly used as auxiliary slow-speed power for anglers, and integral-battery motors built for dinghy propulsion. These are the options a sailor will be looking at when thinking about changing to an electric outboard.

Trolling motors are still popular for low-speed applications, as they are simple and cheap, but they do need a separate 12V battery.

The integral battery motors are sophisticated units designed to give you more speed and greater range for a given power in a small boat, though for any 3-4m boat, the hull speed will limit how fast you can realistically go with any motor unless you start planing.

An electric outboard motor with an integral battery will often include displays showing speed, range at a given speed, and percentage of battery capacity remaining, but these features come with a higher price tag.

The trolling motors and integral battery models in our test were similar in weight and both come in at around the same total weight as a 2.5hp petrol engine.

Four Electric Boat Motors Compared

• By Randy Vance
• Updated: September 17, 2020

Electric marine propulsion is rapidly advancing in market share while providing a fun and unique boating experience not available from internal combustion power.

Electric Motors Then

You might be surprised to learn that electric boats have been around since 1838. Inventors from Prussia, England and America began making vessels with lead-acid batteries—tons of lead-acid batteries per vessel—to move passengers quietly and efficiently. But the internal combustion engines invented in the late 1800s were more powerful and convenient, and with the exception of Elco electric motors, electric power fell away in popularity. In 1934, Minn Kota manufactured the first electric outboard. Then, in the 1960s, bass tournament fishing popularized big-horsepower gas engines for speed, and electric trolling motors for precise boat handling. You might say the fishermen were ahead of the curve by about 60 years on hybrid boats.

Electric Motors Today

We are focusing on production models that can be easily installed by a do-it-yourselfer or OEM without special training. Lithium-ion batteries can be volatile if not properly installed, so some companies require their trained tech to do that.

Electric outboards are expensive, and while we’ve listed the purchase cost, the batteries available are too numerous to name or price, and can cost more than the motor.

A mathematic equation easily converts kilowatt-hours to horsepower, and our math revealed the calculated horsepower to be considerably less than the equivelant horsepower suggested by manufacturers.

Torqeedo provides completely integrated motor, battery and controls. Electronically controlled systems give its motors greater range per battery capacity and, similar to a fuel gauge, help operators conserve energy when needed or tell them when they can splurge on maximum throttle. The batteries are provided by BMW, but it is Torqeedo’s control system that manages output, heat and recharge operations to protect and optimize battery capacity and motor performance.

Range of Power: Outboards from Ultralight 403 at 400 W (about 1 hp) to Deep Blue at 50 kW (about 80 hp equivalent with 20 percent hole-shot boost), and inboards up to 100 kW (about 135 hp).

Most Popular Motor: Torqeedo’s Cruise 10 ($8,999) puts out 10 kW, or about 14 hp, but performs comparably to a 20 hp outboard thanks to Torqeedo’s software. In remote control, it is popular among pontoon boaters in particular, and commonly installed on pontoons used on neighborhood lakes requiring electric propulsion. Through digital controls, peak output is boosted beyond nominal output for a short time to improve acceleration at the hole shot, then returns to nominal output for optimal heat, range and speed control. A side- or top-mount controller—akin to the throttle—will cost $1,399, by the way.

Best Battery: The Torqeedo 48-5000 (5,000 Wh) lithium-ion battery ($5,159) is rated IP67 waterproof; connecting two or more in parallel extends the range.

Battery Compatibility: Compatible with any lithium-ion or AGM battery bank providing 48 volts, the Torqeedo can only operate in smart mode, measuring discharge, heat and other factors to dynamically manage power with Torqeedo batteries. With nonproprietary battery banks, Torqeedo motors mathematically, and less accurately, estimate range and consumption.

Chargers: The 2213 charger ($899) can recharge a 48-5000 battery in under 10 hours. It is rated IP65 water-resistant. The 2212-10 charger ($2,199) can recharge it in two hours.

Elco Motors

Elco has been building electric outboards for over 100 years—a figure that seems implausible to boaters who are beginning to see electric propulsion for the first time. The company’s engineering philosophy has remained the same: build plug-and-play systems, relying on battery power preferred by the customer, and design its motors to fit existing motor mounts, or provide standard transom clamps to make repowering simple and seamless.

Range of Power: Elco builds electric outboards with tiller or remote controls from 3.7 kW (about 5 hp) to 37 kW (about 50 hp). Elco’s inboards range from EP 6 to EP 100, with horsepower equivalents from 6 to 100.

Most Popular Motor: The EP 70 inboard ($15,995) can replace inboard diesel kickers and trawler motors, providing a top speed of 8 to 10 mph (7 to 8.5 knots) and a range of 23 to 41 miles. Its peak output is 51.5 kW (about 69 hp), and continuous output is 29.75 kW (about 40 hp). It needs nine 8-D 12-volt AGM batteries for a total of 108 volts. Lithium-ion batteries are also compatible in comparable volts and amps.

Best Battery: Battery banks from Lithionics are most commonly selected for new builds, and an EP-12 Victron AGM Deep Cycle 12V/220Ah bank is ideal ($5,409).

Battery Compatibility: Elco batteries are completely brand agnostic and connect with any quality battery bank providing the motor’s power demand. However, lithium-ion batteries still provide the most efficiency, along with full power to complete discharge. Even though their upfront investment is often more than double that of AGM batteries, the cost per charge is comparable while also lightening the boat and bringing better performance and range.

Chargers: The ElCon UHF3300 (1x) charger (starting at $825) takes three to four hours to restore battery banks, and the PFC 5000 fast charger reduces the time to two to three hours.

ePropulsion

This company boasts five electric propulsion systems engineered at the Hong Kong University of Science and Technology, and entered the market in 2013. HKUST is also known as the incubator of many electronic products, including the DJI drone. Persistent engineering has brought new innovations to the marketplace.

Range of Power: The smallest offering from ePropulsion is a strap-on stand-up-paddleboard motor. Mainstream power includes two large outboards boasting 1 kW (about 1.35 hp) and 3 kW (about 4 hp) power, two pod drives of the same output, and the most popular portable Spirit 1.0 Plus.

Most Popular Motor: The Spirit 1.0 Plus ($1,999 including charger) is ePropulsion’s top-selling motor, ideal for small vessels, square-stern canoes, tenders and more. It’s a 1 kW motor that the company says offers 3 hp equivalent power with an industry-first direct-drive brushless motor. That’s a quiet arrangement, making the motor lighter and more efficient. It’s got a 75-minute run time at full speed, making 22 miles on a quickly exchangeable, integrated and included floating battery. Take a spare battery ($899) for longer range.

The Navy 3.0, ePropulsion’s latest motor, is 3 kW, or about 4 hp, though ePropulsion claims 6 hp equivalence. It’s available in tiller-steered and remote-control models. Its direct-drive, no-gear-case motor was a breakthrough in electric outboards, using a brushless motor that produced less sound and drag, and increased power and efficiency, offering a more serene experience.

Best Battery: There are three E-Series 48-volt batteries offered: The E40 ($1,200) provides 2,048 Wh, the E80 ($2,000) provides 4,096 Wh, and the E175 ($4,000) offers 8,960 Wh. The data-cable connections in ePropulsion batteries give battery management, enhancing range and speed.

Chargers: Chargers available from ePropulsion are 10-, 20- and 30-amp modes ranging from $300 to $620.

Minn Kota Motors

Minn Kota has been making electric outboard motors since 1934, and its first model was a gear-driven, transom-mounted motor with a tiller. As time progressed, it improved motors slowly until the tournament bass-fishing craze began in the early 1960s. In that time, the motors have been popular as primary propulsion for dinghies and utility boats used for tenders, or positioning the boat for casting.

Range of Power: Models today range from simple tiller- steered motors to digitally remote-controlled motors complete with autopilot features and smartphone compatibility. The Vantage is the company’s primary propulsion motor.

Most Popular Motor: The Vantage ($1,549.99) is not Minn Kota’s most popular motor, but it’s a top contender in the boat market where electric propulsion is desired or required. The tiller-steered Vantage is ideal for use as a kicker for trolling, or propulsion for a tender or small johnboat. The variable-speed motor is digitally controlled to manage and conserve power for optimum range. Forward, neutral, reverse, and power trim to raise it are easily accessible on the tiller of this 24-volt motor. For some reason, Minn Kota does not list specs such as amps, kilowatts or watt-hours.

Best Battery: Minn Kota doesn’t offer batteries, but the motor is compatible with any battery bank producing 48 volts.

Battery Compatibility: Lead-acid, wet-cell batteries are still the most commonly used for small electric motors, but AGM (absorbed glass mat) batteries are more durable, offer more charge cycles, and are quickly replacing wet-cell batteries. Lithium-ion batteries shave 75 percent of the weight of lead-acid batteries, deliver full power to total discharge, and are actually more economical per charge cycle in spite of a 100 percent premium over AGMs.

Chargers: An MK 345 PC Precision Charger ($449.99) provides three-bank charging at 15 amps per bank.

Editor’s Choice: ePropulsion Spirit 1.0 Evo

• Editor's Choice - Top 50 boat gadgets

We're big fans of small electric outboard engines because they're clean, quiet, simple to use and easy to carry.

But the reason we selected this one for the 2021 Editor’s Choice list is because it offers a new feature that we’ve not come across before; the ability to recharge itself when under tow.

Chinese manufacturer ePropulsion calls this innovative new feature ‘hydrogeneration’, (not to be confused with the chemical reaction of the same name).

What it refers to is the motor’s ability to act as a generator when towed behind the mothership in order to charge the battery.

As such, it’s a developmental step on in terms of sustainability from the company’s initial offer, the Spirit 1.0 Plus.

Fitted with a 48 Volt 1kW motor powered by a 1.276kWh Lithium-ion battery, the ePropulsion Spirit 1.0 Evo is maintenance-free.

Recommended videos for you

That is just one of its advantages – others include its light weight, a battery which floats and doing away with the need to store petrol on board.

ePropulsion claims the Spirit 1.0 Evo is equivalent to a 3hp petrol outboard, with a range of up to 22 miles at 4.5mph on a single charge.

At full power the unit can reach speeds in excess of 6mph, but run time is reduced to around 1.25 hours.

At the 33W low end of the spectrum, 36 hours/80 miles is claimed.

Recharging takes 8.5 hours using the standard charger, or 3.5 hours with a fast charger, and all units purchased this year are eligible for an additional year’s warranty over the standard two year term at no extra cost.

We feel the styling of the unit leaves a little to be desired by falling into the ‘boxy’ category, but the main attraction here is functionality.

Quick and easy to deploy, the unit features a simple-to-read digital display which tells you all you need to know about the battery’s state of charge and the power you’re using.

Best of all, it’s a clean choice, a product for the modern age if ever there was one.

Frequently Asked Questions

It’s important to get shaft length right. Too long, you risk hitting submerged objects more frequently and performance suffers. Too short and you’ll cavitate.

At ePropulsion we measure shaft length differently. For electric outboards, the shaft length is measured from the top of the clamp bracket to the centre of the propeller. For petrol outboards, it’s measured from the top of the clamp bracket to the anti-ventilation plate.

Our XS is close to S from Mercury. Our S is close to L from Mercury. Our L is longer than the L from Mercury.

To find the right length for your boat, make sure the top of the propeller is matched to the lowest point of the transom. To do that, measure the transom height (the length from the top of the boat transom to the bottom of the boat. Then simply choose the  recommended shaft length for your transom height.

For most small dinghies and aluminium boats under 15 ft or 4.5m, extra short shaft and short will work, depending on the transom height, some over 40 cm / 15.7 inches, some not. For boats with the transom height higher than 50 cm / 19.7 inches, a long shaft version is more suitable.

For daysailers and short one-design racing sailboats, it depends on the position of the outboard mount. If you choose Spirit 1.0, we suggest you keep the outboard mount at a lower position so XS will work. That’s because XS takes less space to store inside the cabin. For daysailers, sports boats and other sailing boats it’s best to measure the distance from the water line to the top of your outboard mount.

If you still have any questions regarding the shaft length, don’t hesitate to contact us. You can also view this blog post or download the technical drawings of ePropulsion outboards via our download centre.

Absolutely. All you’ll need is an external battery power cable. We recommend the ePropulsion 48V E-Series Battery to extend the range.

Simply store the battery in the dry environment and keep the battery charge level at 60% around, Make sure to charge the battery every 3 months.

Yes, it is designed for extensive use in saltwater. We chose high-quality aluminium alloy as the base material, and applied anodizing coating and powder coating on top of it. For more info, please check ePropulsion Blog: How do we make an outboard corrosion-resistant?

Yes, Spirit 1.0 Plus will switch off after 30 mins without operation.

Works great on tenders, dinghies, and sailboats as well.

The 1,276Wh lithium-polymer battery used to power the motor allows for double the run time and charges within 7 hours. The SPIRIT 1.0 Plus is offered in three different shaft lengths and a patented clamp for maximum stability, making it compatible with most watercraft. The brushless DC motor requires minimal maintenance while offering supreme durability, efficiency, and power for any trip. With a gear-free design, you can finally enjoy nature as it was intended, in peace and quiet. All of these components and features make the SPIRIT 1.0 Plus a great option to use for fishing or short roundabout trips. With a detachable battery and foldable tiller, this electric boat motor is highly portable and easy for anyone to carry.

• Description

It is imperative to accurately measure the transom mount height for an ePropulsion outboard. Having the wrong measurement for the shaft length can drastically affect the performance of the outboard. If the measurement taken is too short for the transom mount, the propeller will not sit deep enough in the water. When the propeller does not sit deep enough in the water it will cavitate and decrease efficiency. If the measurement taken is too long for the transom mount, the propeller will sit too deep into the water. When a propeller sits too low behind a boat, it will have increased water resistance and reduced speeds.

Please note that ePropulsion has a different shaft length measurement from gas-powered outboards. For electric outboards, the shaft length is measured from the top of the clamp bracket to the center of the propeller. For gas outboards, it’s measured from the top of the clamp bracket to the anti-ventilation plate.

*NOTE* TAKACAT, Aircat, Bris and other Fully Inflatable Catamarans  require the  SHORT Shaft – due to shallow transom depth in the water.

ePropulsion Spirit electric outboards now backed by 5 year warranty

ePropulsion is now offering a 5 year warranty across their Spirit electric outboards range, an extension of 2 years over the previous warranty package. Customers will receive the new package (for motors purchased from May 12) at no cost by registering on the company’s website.

There are a three models in the Spirit Series, all of which are covered: the Spirit 1.0 Plus, Spirit 1.0 Evo and Spirit 1.0 Evo Remote. First, the similarities between the models:

All models have a 1 kW direct drive motor that provides thrust and power similar to a 3hp combustion motor.

They can deliver this performance because there is very little power loss between the motor and the propeller. In a combustion outboard the powerhead and motor are at the top of the shaft and require gears in the ‘lower unit’ to transfer the mechanical energy to the prop.

Spirit electric outboards have the motor underneath the water, directly driving the propeller with no power loss from any gearing or linkage.

The battery (which floats) sits at the top of the shaft and clicks in like that on a home power tool. With energy storage of 1256 watts, it can basically run the motor at full power for over an hour.

The simple equation is that in one hour a motor consumes 1 kiloWatt hour of electricity per kiloWatt of power.  With a 1 kiloWatt (1,000 watt) motor and 1256 (1.256 kWh) battery, there’s about a quarter of a kWh (256 watts) available after 60 minutes.

That formula is not always exactly true in real life, because of the way the battery discharges the electricity, but it is a good rule of thumb for roughly gauging the range of an electric motor. The company says that with the Spirit electric outboard on a 12 foot aluminum boat “ on one charge, you can go 22 miles at 4.5 mph, or go fishing all day long at trolling speed .”

An extra battery can also be purchased, with ePropulsion recommending their own E-Series . The E-60 has storage of 3.072 kWh, the E-163 has 8.345 kWh.

Evo Spirit electric outboards feature hydrogeneration

The main difference between the Spirit Plus and the two Spirit Evo models are that the Evo models have hydrogenerating capabilities, meaning that the motor can be instantly converted to a turbine that generates electricity to recharge the batteries.

Find ePropulsion Spirit electric outboards for sale in the PlugboatsMarketplace

This is only possible when the boat has some other propulsion method available, like windpower on a sailboat. The movement of the water under sail turns the prop of the Evo to create the hydrogeneration.

The Spirit 1.0 Plus and Spirit 1.0 Evo have a foldable tiller/throttle. The Spirit 1.0 Evo Remote has the capability for remote steering form the helm of the boat, in either a top mount or side mount configuration.

“We take pride in being the pioneer in the segment when we introduced the free warranty extension in 2021, setting a new benchmark for exceptional service and support to our customers,” said Chang Zhao, CMO of ePropulsion. “By adding another two years to our extended warranty, we believe our uncompromising commitment will set us apart in the industry and hope this encourages more boaters to make the switch to electric propulsion.”
