Electric Outboards: Less than 5 kW

It is the long term goal of Plugboats to provide a complete range of ‘Buyer’s Guides’ to electric motors, recognizing that it is a large task. We feel it is important, though, because there is no place we know of where someone interested in electric boats and motors can conveniently find this information. This is our first guide: electric outboard motors under 5kW (excluding kayak and trolling motors). Our next guide will cover those kayak/trolling motors, followed by an electric outboard guide of 5kW+, then a guide to pod motors and then inboards. We welcome all suggestions and feedback. (Use the Comment Form at the bottom of the page)

Outboards under 5kW

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.

General Organization

They are organized in alphabetical order by manufacturer and 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.

The blue links will connect you to the manufacturer’s entire website, the page for the motor/s being detailed, and in some cases, a link to download a brochure. At the bottom of the page is a sortable and searchable table of all the information. While the page can be viewed on a mobile device, there is a lot of information. We encourage you to view on a desk or laptop browser for maximum legibility and flexibility.

Plugboats makes no claims about the relative performance or manufacturing quality of the motors, the information is drawn from each manufacturers published materials. Also, the photographs and drawings are not shown in any consistent scale.

We welcome any input you may have to make this guide better – a different grouping, perhaps we have left out a motor or are unaware of a manufacturer. If you do have a suggestion, correction or improvement, use the Contact Form at the bottom of the page.

Measurements

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 indiccate 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.

Price: These prices are intended as a guide, to give an idea of comparative pricing, not as quotes for the products. The information was taken from a variety of sources. If the manufacturer has a suggested list price, it is noted. Otherwise, information came from dealer websites. In some cases we could not find a dealer price and we have contacted the manufacturer for a MSRP. These will be added as they arrive.

The range of prices reflects the options for the model (i.e. from short shaft tiller steer to long shaft remote steer). 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.

Aquamot

Aquamot was founded in 2003 by Ing. Siegmund Hammerstrom and has grown to be a leading manufacturer of electric motors. They have outboard and pod motors in sizing from 1.1 kW to 25kW. The motors are divided into the 1 to 1.6kW range and the 2.2 to 4.4kW range because that is how they are shown on the website. The photos show that the motor (bottom of shaft) is longer and larger on the higher kW models. The black extension is the optional tiller.

Elco

Elco (Elco Motor Yachts) is the oldest electric boat motor company in the world, having been started in 1893 as the the Electric Launch Company to supply electric boats for the Chicago World’s Fair. It went on to become the USA’s second largest boat manufacturer. In 2013 the company decided to focus exclusively on electric motors – outboards, inboards and hybrids. They have two outboards under 5kW and four bigger motors ranging from 6.48kW to 21.6kW.

EP Carry

Joe Grez, an experienced consumer product developer with a degree in physics and portfolio of US patents, developed the Electric Paddle in 2008 when a new mandatory CO2 warning had to be placed on his dinghy and it made him think about the effects of exhaust on his young granddaughter when she was in the boat. The motor has now evolved into the EP Carry system, an electric outboard for dinghies and most boats 13 ft. or less, plus some sail craft.

Ray Electric Outboards

Morton Ray holds a Masters Degree in Electrical Engineering from Carnegie Institute of Technology and developed his electric outboard in 1973 as a primary power for boats, as opposed to the trolling motors people were using as auxiliaries to their gas motors. Ray Electric Outboards Inc. approaches electric propulsion differently from other companies. It manufacture one motor, the watt power of which can be changed by altering the voltage of the accompanying battery pack and the amperage.

Torqeedo

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.
