It functions as an electric motor below 1,500 RPM and a RPM dependent switch turns it into a generator around 1,700 RPM. If you have a long no wake zone to navigate you better have a BIG battery or two. With a battery ignition when the battery is dead, the motor is dead. This 12 volt electric starter was offered on several models of Evinrude, Elto and Johnson. Evinrude also offered it as a trolling motor. . . 😆
