Torqeedo’s lightest outboard, the Ultralight 403 A & 403 AC, get you to your favorite spot faster, and lets you stay there longer. It offers reliable performance, an innovative new angler mount and all the high-tech features of a genuine Torqeedo system: GPS built-in, real-time range and runtime display, solar charging and the latest lithium battery technology.

Our extremely light Ultralight 403 A & 403 AC fit on all popular types of kayak and canoes, and there are special models for special requirements.

The difference between the 403 A & the 403 AC is that the 403 A comes with a 320 Wh Lithium Ion Battery and the 403 AC comes with a 915 Wh Lithium Ion Battery.  Otherwise they are identical.

Information on range and speed

For a displacement boat making way through the water, the required propulsive power increases in proportion to the cube of the speed. This means that if you want to double your speed, you need eight times as much power.

And vice-versa, a small reduction in speed is enough to increase the achievable range substantially.

The Torqeedo Ultralight's on-board computer calculates the remaining range constantly, by linking the motor's consumption data with the charging level of the batteries, and the speed over the ground from the GPS. This allows you to read the remaining range in real time from the motor display or the smartphone app TorqTrac.

* Torqeedo static thrust measurement is based on internationally accepted ISO standards. Static thrust figures for conventional trolling motors are typically measured differently, which results in higher values. To compare Torqeedo static thrust data with conventional trolling motors, add approximately 50% to the Torqeedo static thrust values.
