ABSTRACT:
To provide an engine control unit for facilitating steering control. In particular, the invention relates to a controller of a boat propelled by jetting water pressurized and accelerated by a water jet pump. If a throttle angle of an engine for driving the water jet pump is a predetermined value or less and a steering angle by a steering handlebar of the jet propulsion boat is a predetermined value or more, a throttle valve of the engine is operated in an opened direction and advance angle control is made over the normal ignition timing of the engine.
