Ships when available.

The ultimate tool for kayak fishermen or any paddler who wants some extra power to charge through current, wind or fatigue.

Sold as a complete package, the system includes a throttle/gear shift, “kick up” mount, ultra-quiet, efficient motor and a GPS housed with the 29.6V, 11Ah lithium-manganese battery. With a data feed from the GPS, the throttle/gear shift includes a digital display for battery state of charge, remaining range, speed and current input power.

Capable of powering a kayak or other light boat for up to 10 hours at 2 1/2mph, this motor works great for trolling or holding a position in windy conditions. It is also a great choice for ocean kayakers who want a reserve motor for safety reasons—or for family kayakers who like to paddle, but who also appreciate convenience.

    Comments about Torqeedo Ultralight 403 Kayak and Light Boat Motor:

    Great electric motor for a kayaks or small boats. I have Hobie Bravo (12' catamaran sailboat) that weighs 200lb and an overall weight of 600lb with two adults. Depending on conditions, I can achieve a speed of about 3.5 mph. The motor will display the current speed in mph or knots and also give you an estimate of the range left on the battery given your current speed. Although expensive, it is of great quality and well-built (made in Germany) and very lightweight which is a plus if you have a small kayak, boat, or sailboat. Overall, this is a great motor that is powerful and lightweight.
