Torqeedo Ultralight 403 Kayak Motor

A motor on a... kayak?

Brilliant! And we're not talking about some random motor. This is the Ultralight 403! Weighing only 7 kilos (including the battery and throttle), this motor won't hold you back. It will give you a little thrust power when you need to paddle against the current, against the wind or simply when you're tired. And make no mistake, this ultra light motor is much more powerful than it looks and demonstrates real endurance.

Great battery life

Whith a fully-charged battery, you will be able to sail 42 km (depending on your kayak) if you set the speed to 4 km/h, which is quite easy because you can read the exact speed of your kayak on the Ultralight's display. The built-in GPS constantly calculates the remaining range for you. To do this, it combines the consumption data from the motor with the charge level of the batteries together with the speed over water obtained via GPS. This means you can read the remaining range in real time from the Ultralight's display. And if the remaining range isn’t enough for you, just take the solar panel on board and you can charge as you go.


The Ultralight features a throttle with display that provides information on the battery, remaining range, speed over ground and input power.

Easy assembly

Thanks to the mounting ball which comes with the battery, the Ultralight can be mounted on almost any kayak. All the elements included in the package (motor, battery and throttle) are totally waterproof (IP67). That's why the Ultralight 403 is perfect for sea, river or lake kayaking on flat water.


The engine runs only if the magnetic key is applied on the throttle and stops when it's no longer on it. For more safety, this key should be tied to the user's wrist or life vest.
