At the top of the page is an illustrated guide, and on the right is a photo of the motor and specifications.
At the bottom of the page is a table, if you know you are looking for a certain type of motor (ie pod or sail drive), a certain power range or a certain weight/length boat, you can search for this table. If you plan to use the form, it’s best to view the page on your computer instead of on your phone or tablet.
The motors are arranged in alphabetical order by manufacturer, then the type of motor, namely fixed pod, steerable pod, sail drive, and then the motor power in these lists. For many styles, multiple motor powers are available, in this case, we have made it as easy as possible to align the motor to its specifications. That is, if there are three kinds of motor power with different weights, they are recorded as kW: 2kw, 2kw, 3kw • Weight: 10kg, 12kg, 15kg. For some manufacturers, the changes are more complicated, and we have done our best to make it simple and easy to understand.
There are many ways for manufacturers to specify the technical attributes of their products. We have tried to adopt the most common measurement methods and make an "apple to apple" comparison. See note in "Measurement" below
The photos and drawings are from the manufacturer's website and are not shown in any consistent scale.
kW • Voltage • Current • HP: Not all manufacturers list all these specifications. We have included the available specifications and used the N/A symbol where it is not available.
kW is the kW rating provided by the manufacturer. Most websites do not indicate whether it is input or output kW. When it was instructed, we got the output.
Voltage is most often referred to as "voltage" on websites. Some indicate nominal or peak values. We use nominal and indicate whether the peak value is also quoted.
It is currently indicated when the manufacturer provides the information. Usually it is in ampere: A. In some cases, the manufacturer uses ampere-hour: Ah, we have indicated it where it is used.
HP: is the "HorsePower equivalent" so that you can understand the power of the motor by comparing it with the HP rating that you may be more familiar with. If available, these measurements come from the manufacturer’s website, and different manufacturers measure HP in different ways. Some even use metric horsepower, which is slightly different from imperial horsepower. Once again, we tried to make it as Apple to Apple as possible. (As a general guide, 1kW is the first round, one-third of HP 1kW=1.3HP, or conversely, 1HP is approximately three-quarters of kW: 1 HP = .75kW).
Static thrust. Torque, efficiency: This may be the most variable specification. We only provide any information (if any) that the manufacturer publishes on its website.
Voyage and operating time: We did not include an estimate of the voyage or operating time, because it depends on too many factors: battery size (and sometimes type), water conditions, speed, etc. Except ePropulsion and Torqeedo models, they have batteries from manufacturers that specifically match the motors, so estimates are provided on their website.
General: If a manufacturer publishes a specification, we have tried to include it here, even other strict manufacturers may not include the same type of measurement.
Weight and length: in metric system. Tons: Metric ton is considered equal to English ton (1 ton = 1.1 ton), kilogram: (1 kg = 2.2 lbs, (15 kg motor = 33 lbs), 1 meter = 3.3 feet (10 meters ship is 30 feet))

Kräutler is Austria's long-established manufacturer of industrial electric motors. They started building electric boat motors in the 1980s, mainly because they couldn't find products that met the founder's Oswald Kräutler standards. They produce motors for industrial and marine and recreational ships, and may provide the widest range of sail pods and sail drives on this page, from small 0.5kW steerable pods to electric rotating sail drives with power up to 30kW.
About the Kräutler section of this guide: Kräutler fixed pods can be equipped with AC motors (ACV) or DC motors (GPV). AC is suitable for smaller vessels. They also have two different configurations: fixed propellers and folding propellers. To make this page shorter, we have divided them into motor types for written description, but in the image we show you fixing and folding options. In the table, each motor has a separate list. Note: GPV motors are only suitable for short-term use in salt water.
All Krautler motors with specifications shown in the fixed sail drive above can be installed with the mechanically rotatable option shown here or the electric rotatable option shown below. Sail-Drive is equipped with a fiberglass base base, which can be laminated to the hull (depending on the size of the motor). For existing Volvo and Yanmar foundations, Sail-Drive is equipped with an adapter plate that can be directly screwed to the existing foundation.

Oceanvolt ServoProp is a patented variable pitch sail drive that "combines a high-efficiency sail drive with the most powerful hydroelectric generator on the market." The unique function is that the propeller blades can be rotated more than 180 degrees. The software-controlled variable-pitch sail driver automatically adjusts the pitch of the propeller blades to optimize power generation and power output. The blades are designed to maximize the efficiency of the system in terms of forward, backward and regeneration. When the blades are set to the neutral sailing position, the propeller will produce extremely low drag, similar to the drag of a feathered propeller. ServoProp can generate more than 1 kilowatt of power at 7-8 knots and more than 3 kilowatts at 11-12 knots.
