»» Plugboats also has the world’s largest and most complete Directories of electric boat suppliers with over 600 companies listed, including manufacturers, dealers and distributors of: electric boats, motors, outboards, inboards, pods, saildrives, motors, batteries, chargers and accessories, as well as electric boat rentals and charters.
This is a general outline of the companies that manufacture electric outboards with power under 5kiloWatts and the models that they offer. It is not intended to be the definitive authority on the subject, but rather a launching pad for finding out more about motors that may match your specific needs.
There is a lot of variety in the way manufacturers detail the technical attributes of their products. We have tried to take the most common measurements and assemble an ‘apples to apples’ comparison.
The top of this web page is an Illustrated Guide with photos of the motors and specifications to the right. At the bottom of the page is a Sortable/Searchable Table that lets you compare motors easily. If you are going to be using the table extensively the page is best viewed on a computer rather than smartphone or tablet.
The motors are organized in alphabetical order by manufacturer, then by power of motor within that manufacturer’s listing. In the interests of user friendliness, we have bunched the short (S) and long shaft (L) models together, and for some manufacturers have also bunched the range of motors, mainly because that is how those manufacturers display them on their websites. For the specifications we have tried to make it a user friendly as possible. If there are 3 models in the line, we will give the specs for each model with a comma in between. If there are many models, we give a range without lining the specs up with specific models.
The table can be searched with any keyword – manufacturer, for instance, or can be sorted by any of the columns: Power, Motor Type, Shaft Length, Other Miscellaneous information, Country of Manufacture and Price.
All specifications are taken from the manufacturers’ websites or brochures without any independent verification. There is a lot of variety in the way manufacturers detail the attributes of their products, particularly when it comes to ‘Power’. Some use peak power as the measurement, some use continuous power, and there are other variations. Some quote minimum RPMs for their motors, others quote maximum RPMs. There is also no set standard for ‘horsepower equivalent’. We have tried to present the information as close as possible to an ‘apples to apples’ comparison.
The photographs and drawings are from the manufacturers’ websites and are not shown in any consistent scale.
kW • Voltage • HP kW is the kW rating provided by the manufacturer. Most websites do not indicate whether it is input or output kW. When it is indicated, we took the larger of the two, usually the input kW Voltage is most often referred on the sites as ‘Voltage’. Some indicate nominal or peak. In those cases we have used the nominal rating and indicated it as such. HP is ‘HorsePower equivalent’ so that you can get an idea of the power of the motor in comparison to a HP rating you might be more familiar with. These measurements come from the manufacturer’s website, and different manufacturers measure the HP in different ways. Some even use metric horsepower, which is slightly different from imperial horsepower. Again, we have tried to make it as apples to apples as possible. (For general guidance, 1kW is round one and a third HP, or the reverse is that 1HP is around three quarters of a kW
Weight and Length are in metric. 1 kilogram = 2.2 pounds, ( a 15kg motor = 33 lb), 1 centimetre = 2.54 inch (63 cm shaft = 25″)
Running Times These obviously depend on a variety of conditions. We have used the information from the manufacturer’s website, taking the range/time at the lowest speed and highest. Some manufacturers also include range in their analysis of the capabilities of a battery and motor combination, but since not all provide that, we have used only running times.
Motor Types There are advantages and disadvantages to each kind of electric motor. Some manufacturers use abbreviations to describe their motors, others use the full words. We have used whatever the manufacturer prefers, but when abbreviations are used, this is what they mean:
We have included prices only when listed on the manufacturer’s website. Many manufacturers will have pages on their sites with dealer locations and links to dealer websites where pricing can be found.
While prices between dealers are fairly consistent, there can be big price swings between continents. The $ amounts are US$ unless otherwise noted. Finally, if the battery is integrated, it is in the price, if the battery is separate, the listed price is for the motor only.

Ray Outboards is a 3rd generation family-owned business founded by Mort Ray, who began designing his first electric outboard motor in 1973 in his basement and was manufacturing motors for sale by the next year. Morton passed away in 2018, so his family has taken up his mission to provide reliable, environmentally safe motors for the world. Ray manufactures one motor model which can operate at different power ratings according to the battery pack attached. The company does not provide kW rating, so these have been estimated from the voltage and amperage inputs.
Remigo is a Slovenian company that has taken a totally fresh look at small electric outboards and has come up with a unique design with a mounting bracket on the boat’s transom that allows the motor to easily detach for stowing or carrying. It has a distinctive pillar design with integrated battery and 2 button control module.
Rim Drive technology is a Netherlands company with a line of rim motors in which the propeller blades are affixed to a rim rather than a central hub. There are no wearing parts within the motor and much reduced chance of weeds or other debris snagging or clogging. The motors are available as outboards, pods, azimuths and thrusters. In outboards, the company offers three models with less than 5 kW of power and two models with powe greater than 10 kW (see our Guide to Electric Outboards >5k)
The Stealth electric outboards were developed by Scott Masterson of Houston with the underlying concept of having parts for an electric motor as easily available as those of a gas outboard. The lower unit, shaft and body come from a competitor of Yamaha outboards and an electric motor and controller is installed in place of the ICE powerhead, fitting under the cowling and enabling the outboard to be installed and operated in the same way as a fossil fuel motor but without the fumes, noise and maintenance.
The Stealth Switch can be purchased with batteries from 24V to 96V, enabling you to change power without changing the whole motor. A 24V battery will provide a 6 hp /4.5 kW motor and by adding batteries in series it can become a 12 hp / 9kW or a 25 hp / 18 kW motor.
TEMO is a French company passionate about the world of boating and sailing’s liberating way of life. They have two innovative electric outboard motors under 5 kW: the 450 and 1000.

The TEMO 450 has won multiple international awards including the Made in France Grand Prix for Innovation, DAME Design Award at METSTRADE and IBEX Innovation Award. The TEMO 1000 earned a Special Mention at the 2023 DAME Design Awards.
The TEMO 450 Carbon has increased autonomy over the TEMO 450 thanks to a battery with 12.8 Ah rather than 10 Ah. This enables 1 full hour of autonomy at top speed.
Torqeedo is the leading manufacturer of electric outboards in the world. The company was founded in 2004 by Dr Christoph Ballin and Dr Friedrich Böbel when they decided they could build a better electric motor than the one on the boat Dr. Ballin had just purchased. The company offers trolling motors, inboards, outboards and pod motors and works with BMW’s battery division as well as partnering with many of the world’s premier boat designers and manufacturers. Apart from its line of small power kayak and trolling motors, it makes 5 models of outboard with power of less than 5kW.

Thanks, Great reference for options. Looking forward to the bigger motors.
Thank you, this may be an idiot question, but we not include a popular trolling motor it two. Seems that is the bug question to me. They are a lot less expensive, how do they stack up?
Hi Timothy. Thanks for your question, not idiot at all! Just working on the trolling motor guide as a separate category, along with kayak motors. There will be some overlap with this. It should be ready next week.
Torqeedo Cruise 4.0 is 48V not 24.
Thanks for the under 5kw guide – very useful. There is a problem about comparing electric outboards with petrol ones. The electric ones quote Thrust in lbs, with a rough HP equivalent. In general they seem to work on 1kw=3HP (not 1.3HP as you suggest). Petrol ones do not quote a figure for Thrust, but I have found a suggested range of 20-25 lbs per HP. That means a 3HP petrol engine would produce 60-75 lbs thrust. The 1kw electric motors produce around this (Torqeedo 1003C – 68 lbs; ePropulsion Spirit 1.0 – 66 lbs; Aquamot Trend 1.1 – 72 lbs).
Of course there is a difference between the power produced by a petrol engine, some of which is lost through the gearbox, and the thrust produced at the propeller by an electric engine. But the general relationship of 1kw=3HP looks about right.
Do you know of any detailed research into this? Could you do an article on it?
I think it would be worth adding a column giving thrust figures in your table of outboards under 5kw.
Thank you for the comprehensive list of electric outboards!
Do any of the electric outboards also work as hydro generators, perhaps after swapping out or adjusting the prop? Kind of silly to carry both an electric outboard and a hydrogenerator on a boat like a Corsair 880.
The ePropulsion Spirit 1.0 has a hydro generation model.
Any idea regarding the Torqeedo 4.0R BMS compatibility with lithium batteries BMS from other manufacturers? Thank you.
Alle the ePropulsion Evo Models work as hydro generators… don’t know about the others. Got a Spirit Evo and that works well.
I owned a boat with a Rimdrive from RDT, same units as they are selling now as outboards. Great system, especially in water with a lot of debris in the water as this prop can easily be cleaned but simply stopping it a letting everything that is in, flow out.
