Simply put, just like any rope start motor, it generates its own electricity. To make a comparison, lets discuss the electrical system of a carbureted 25 horsepower 2-stroke for a moment. The basic system design has been around for over 25 years. Underneath its flywheel is a single charge coil, which produces the voltage to operate the ignition system. There's also a very small stator to provide electrical power for AC Lighting or optional battery charging and, there's a sensor coil which provides the ignition timing. Since Evinrude E-TEC doesn't need a charge coil or a sensor coil (because these functions are controlled by the EMM), a full-diameter stator which uses more windings compared to the 25 model above, is employed. Powerful rare earth magnets are used on the flywheel and, by adapting our patented switching stator technology, the stator is able to generate more current at lower rpm. The voltage required to turn on and "boot up" the EMM is delivered in a few milli-seconds. By integrating pulse width modulation technology (which has been used on electric trolling motors for decades), we are able to power up the electric fuel pump and not put an excessive demand on the electrical system while starting the motor. The EMM and fuel pump power up take place in the first third of a revolution of the flywheel. The EMM then determines crankshaft position via a sensor which "reads" the flywheel encoder vanes - all of this occurs within the first complete flywheel revolution. This leaves plenty of rope to pull and provides ample voltage to subsequently fire the injectors and ignition and get the engine running.
