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.

AS Labruna was founded in 1971 and built an excellent reputation for its diesel marine engines, generator and propulsion systems. In the 1990s it started an E-Vision division to manufacture marine engines that reduce environmental impact. These systems include battery-electric, hybrid systems combining diesel and electric, and systems utilizing hydrogen fuel cells. In addition to the EX-10 and EX-20 below, they also have the EX-10 that can be found in our Guide to Electric Outboards Under 5 kW.
Aquamot was founded in 2003 by engineer Siegmund Hammerstrom and has grown to be a leading manufacturer of electric motors. They have outboard and pod motors from 1.1 kW to 25kW. Covered below are the 11kW to 25kW motors. Measurement: Aquamot uses a power measurement of “comp. thrust comb engine. (PS)” Which we are taking to mean “comparable thrust to a combustion engine (PS)” PS is the German abbreviation for a metric horsepower: PferdeStärke and we have used this for the HP figure.
Aquawatt founder Dieter Seebacher has been building electric boats since 1989 and the company is now truly a 360 degree firm, making boats (from small inflatables and barges to runabouts and sleepers), inboard motors, outboard motors and batteries. Propellers are sold separately from the motors and are matched to the motor and usage.
Bellmarine has a history going back to 1999 and involves a motor manufacturer merging with a battery accessory manufacturer and then being purchased by Transfluid, a large scale industrial motor manufacturer. Perhaps for this reason, it is a very modular system and difficult to compare with other outboard motors and almost impossible to price compare. This is compounded because the Bellmairne outboard is essentially a saildrive system bolted on to the back of a boat. Having said that, these are the specifications on the Bellmarine website. Measurement: Bellmarine does not provide any HP or thrust information, but focusses on RPMs and propeller size. HP cannot be calculated without torque specifications, which are not available on the Bellmarine website or in brochures.

SeaDrive is a Norwegian manufacturer that has an innovative approach to electric motors for which they received a nomination for a 2019 DAME Award. The concept is that the basic motors can be configured as outboards, fixed pods, steerable pods, a saildrive or lift-up azimuth side pod – also with the ability to have the propellers arranged for push propulsion or pull propulsion. There are also regenerative versions available. The systems come in three power ratings: 7.5, 15 and 30.
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.

Thanks from Austria for these more than useful and professionaly researched and presented informations. BR Wolfgang
Thank you. Glad you have found it helpful!
Thanks from Norway. Very nice, and the first real collection of different brands that I’ve seen. Regards, Pelle
Great info. Thanks. The cost of an electric motor compared to a standard petrol is crazy money. Can’t justify the massive cost to go electric yet.
You have the most informative website I’ve ever seen, factual, direct and well explained. Unfortunately all of the motors shown are out of my price range, (I have rolls Royce expectations and mini cash), that said, if I ever win the lottery I would put great faith in your website. Thankyou for your explanation and obvious amounts of time given and wish you well for the future, regards Rob (England)
Very nice to have all of this information here!
I’m having a hard time finding comprehensive surveys of reliability. I think it would be phenomenally useful to allow me to easily see and sort by how reliable the manufacturer _thinks_ their motor is: sort by warranty length.
Evoy in Norway now makes an awesome electric outboard.
Looks like in the area of 30-45KW we don’t have a big choice in Europe – overpriced Torqeedo or Aquawatt. Would be glad to see bigger competition.
Excellent resource – thanks for compiling this list
Excellent. This is also a great guide to determine a potentially much less expensive DIY approach. Used outboard motors may be converted, with a bit of patience. As for the ICE cost comparison: happy hour cruises are very peaceful with electric.
Reviewing from Australia this information has been highly informative and has abled me to enquire more specifically to manufacturers around the world. Much gratitude for the compilation of information.
