Abstract
A watercraft has a throttle position sensor, an engine speed sensor, and a start switch. The sensors communicate with a controller. The controller can regulate engine speed. The controller regulates or limits the engine to a low speed when the throttle angle is above a predetermined value during startup, and/or when the engine temperature is too low.
