This quiet and efficient electric motor will dramatically expand your horizons. With the Hobie evolve, you can either maintain steady cruising speeds of two knots (motor only) for hours, or you can open the throttle for short sprints. Best yet, depending on your set-up, you can use the evolve to augment your boat speed while also using your MirageDrive. And thanks to its cockpit-mounted Remote Throttle, you always know how much juice you have left in the system. 320 Wh Lithium-Manganese battery. Runtime estimated as 8 hr 20 min at 2.6 mph / 48 min full throttle. Designed to work with any Hobie kayak that has a MirageDrive (except Inflatable series kayaks).
