ULTRALIGHT (Ball Mount) 403 vs 403C

 

Torqeedo’s lightest outboard, the Ultralight 403 and 403C, get you to your favourite spot faster, and let you stay there longer. They offers reliable performance 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 and 403C come with the universal ball mount for easy mounting on all popular types of kayaks and canoes (The alternative Angler Mount is also available, see our ULTRALIGHT 403AC &1103AC).

The key difference between the 403 and 403C is the larger capacity 915Wh battery in the "C" model for extended range versus the 403’s lighter but still punchy 320Wh battery.

 

Ultralight 403 and 403C – Benefits:

  • Weight including battery: 8.8kg (403) / 11.0 kg (403C)
  • Range of up to 35km (403) / 100 km (403C)
  • Easy to install universal ball mount (New Angler mount also available, see our ULTRALIGHT 403AC)
  • Completely waterproof (IP67)
  • Superb usability with a wealth of smart features
  • 320 Wh Lithium Battery (403) / 915 Wh Lithium Battery (403C)

 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.
