Popular electric boat engines
„Which e-drives are available for my boat?" - you will easily find the right type of motor and the right model for your boat in the categories. Here you will find almost all manufacturers and models available on the market for maritime applications.
You are not sure which electric boat engine is best suited? Give us a call! We have a selection of over 500 different electric drives from over 20 manufacturers.
Types of electric boat drives - Which are available?
E-Boat engines are available in all power ranges. You will find all variants from 0.2 kW up to 144 kW (200 HP) power in our shop. Depending on your requirements, you will need about 1-2 kW power per tonne in displacement mode and exponentially more in gliding mode.
The control of your e-propulsion is, on the one hand, possible via the tiller on outboards directly at the engine. On the other hand, the remaining engine types can be controlled remotely by means of a remote throttle and steering wheel or a special remote control. For this purpose, the throttle lever and display are installed in the steering position of your boat.
Performance and general characteristics of e-boat propulsions
Which type of engine you need depends strongly on your boat. Motorboats usually have an outboard or inboard motor installed. Sailing boats can be operated with various types of engines. Also with outboard or inboard motors, but also with (rotatable) pod motors or sail drives.
Smaller inflatable boats or rowing boats are often powered by a stern drive motor or, for more power, by an electric outboard motor. In addition to stern motors, bow motors are also suitable for anglers, often with an autopilot and separate remote control. For each type of boat, you will find something in the following categories!
Differences of the individual boat drives - What do I have to pay attention to?
The selection criteria vary depending on the boat and application. One of the most important criteria for us is the volume. There are e-drives with gears that generate a high-frequency whirring sound. These are significantly quieter than combustion engines, but still relatively loud.
And there are loud electric outboards where absolutely nothing can be heard. We find peace and quiet on your boat should not be disturbed by anything. We therefore clearly recommend a silent model without a gearbox. You can also find the information at the individual products or you can filter by them.
E-drive for leisure vs. commercial use
There are differences between leisure and commercial use. For recreational use, the models from Torqeedo, ePropulsion and Aquamot have the best prerequisites with an unbeatable price-performance ratio.
If you use your boat as a hirer or in the industry for commercial purposes or if the demands on travel time per year are very high, we recommend specially designed engines from the premium segment. Ideally suited for this are the motors from edyn, Kräutler, E-Tech, or the professional line from Aquamot.
Electric boat drives - Which manufacturers are there?
Most boat owners are familiar with Torqeedo with the bright orange logo. Torqeedo comes from Starnberger See in Germany. Torqeedo is the market leader in the field of electric boat drives and has already delivered more than 100,000 electric motors all over the world.
The absolute hit in the field of sterndrive engines for anglers and smaller motorboats is Minn Kota from the USA. The engines are in the lower power range and are even cheaper in this range compared to the combustion engines and have replaced the internal combustion engine for a long time.
ePropulsion is an emerging manufacturer of electric boat engines and has in the past surprised with a very strong price-performance ratio. Also, the latest batteries for ePropulsions electric engines systems caused a positive surprise in the maritime industry.
In addition, there are still very well-known manufacturers such as the companies Kräutler, Aquamot, E-Tech, or RiPower. These manufacturers are known for their high quality and have been producing e-drives for boats and shiHP for a small eternity. Especially for larger boats, we recommend these manufacturers.
Advantages and disadvantages of electric boat drives
On the one hand, electric boat engines have the conventional advantages of an electric motor. The same has to be considered when comparing the combustion engine and the electric car. The electric motors are quiet, clean, and very efficient. Besides, the engines have much better handling, maneuverability, and more thrust in the lower speed range. E-boat engines are also more affordable to maintain, safer than combustion engines and also environmentally friendly.
There are some prejudices about electric drives. One topic is the range and capacity of batteries. Most of the time the range is even greater and not an issue. In 95% a combustion engine can easily be replaced by an electric drive. The only exception are gliding boats, where you have to take a closer look if an e-motor is already realistic.
The acquisition costs of the e-boat motors are usually more expensive. That is true. On the other hand, there are no maintenance costs and operation is much cheaper thanks to the electricity. Normally, a complete propulsion system pays for itself after 3 years of operation. Also, the batteries are said to have a bad environmental balance. Depending on their size, batteries are often no worse for the environment than jeans or a kilogram of beef and are hardly an issue in terms of the environmental balance.
Another point is the charging time and weight of the batteries on board. The charging time is usually between 6 and 10 hours, which is the usual time for boats to be moored in the harbor or marina. The maximum weight also plays a role in sliding boats. The batteries replace the tank and thus usually take up hardly any more space, but weigh a few kilograms more if you need a really large battery or use AGM batteries.
Batteries for an electric boat drive
For the battery, you have the choice between lithium and AGM batteries. The choice depends entirely on your needs. The criteria are weight, range (capacity), flexibility, charge cycles, depth of discharge, and cost. Each battery type has individual advantages and disadvantages.
The best-known batteries are lithium-ion batteries. These are offered by most manufacturers directly matching the electric motor. The advantages are very high capacity and high depth of discharge with a high number of charging cycles. As a rule, the batteries can be discharged up to 3,000 times and are very durable. The batteries are therefore currently in the premium range and costs are correspondingly higher. Furthermore, lithium batteries weigh only about 1/3 of conventional AGM batteries.
AGM batteries are also often used in marine applications. The advantage is mainly lower purchase cost and is relevant for boats where weight and flexibility are not important. Mainly sailing boats and displacers. Conventional AGM batteries have only about 750 charge cycles and a discharge depth of 50%. Below the recommended depth of discharge AGM batteries are irreversibly damaged. We only recommend AGM batteries with Deep-Cycle or Super-Cycle, which can be discharged up to 80% or 100% and are therefore comparable to lithium batteries.
