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.
