Electric inboard motors for displacement boats.

Narrowboats, river launches and sail boats.

Torkmar builds direct-drive high torque PMAC motors and complete electric systems — motor, battery, solar, and power hub — guaranteed to work together.

Back To Front Thinking

We think too much time is spent thinking about the motor and not enough thinking about the propeller. Ater all, it's the propeller that makes the boat move not the motor.

Torque is Our Jam

Torque is a rotational force. A large prop needs a high torque electric motor. Likewise, you need a lot of torque when opening a stubborn jam jar.

Steady As She Goes

Force applied gently over a large area is more effective on water than a harshly applied force in a small area. Choose a prop, then a motor for the most efficient solution for your boat.

Which Type of Boat Are You Building or Converting?

Electric Narrowboat

Silent locks, birdsong, water rippling past the hull — narrowboating was never about arriving. A high-torque Torkmar motor turns a large, slow prop, making every mile of canal the destination.

Electric River Boat

The river is the journey — birdsong, reeds, water under the bow. Torkmar's direct-drive PMAC motors deliver smooth torque and near-silent cruising, so every unhurried mile becomes the point.

Electric Sailboat

Sailing was never about arriving — it's wind, water, and wildlife along the way. A Torkmar electric inboard keeps the journey quiet, with reliable auxiliary power, regeneration underway, and low maintenance.

Start with the propeller; then the motor; then everything else.

Low speed 20″ -18″ Propeller on a narrowboats, less than 1000 RPM

Step 1 – Size the propeller first

A large, slow-turning prop grips more water with less slip. For heavy displacement — 18–20 inches at under 1,000 RPM.

Step 2 – Match the motor to it

Our PMAC motor produces maximum torque from zero RPM — no warm-up, no gearbox noise. Wound specifically for low-speed, high-torque work.

Step 3 –Design the whole system

Battery, solar, and power hub are spec’d around your motor’s real demand. Tested together — one warranty, one supplier.

Eco Friendly Boating with electric inboard boat motors

Eco-Friendly Boating on British Waterways
When switching to a Törkmar electric inboard boat motor, you are contributing to the preservation of the network managed by the Canal & River Trust. Electric drives eliminate oil leaks, particulates, and noise pollution. Above all our customers often tell us, “I do not miss my old smelly diesel motor one bit.”

Join the Electric Revolution
The shift to electric boating is documented globally by directories like Plugboats. Whether you are refitting a classic boat or commissioning a widebeam, a Törkmar marine electric motor is the heart of a modern vessel.

Converting your boat. Diesel motor out. Marine electric motor in.

Investing in an electric inboard boat motor is a significant decision. We can help! The Torkmar team offer expert advice born from real-world experience to help you navigate the technical details. We’ll look at your boat’s weight and your cruising style to recommend a tailored solution. Because we supply everything from solar panel to the prop, we guarantee a balanced system, taking the guesswork out of electrification.

But Why Choose a Torkmar Electric Boat Motor?

High Torque: Continuous output to swing large props (up to 20 inches).
Variable Speed: Precise control from a crawl to cruising speed.
Low Maintenance: Significantly fewer moving parts than a diesel engine.
Easy Integration: Designed to fit standard engine bays for new builds or conversions.
