ABSTRACT:
A personal watercraft includes a hull and an engine. The engine has an air intake system through which air is delivered to combustion chambers of the engine. An overturn switch detects overturn of the hull. A control device stops an operation of the engine based upon an output of the overturn switch. A throttle valve is disposed in the air intake system to be actuated by a throttle valve actuator. The control device controls the blocks the intake system based upon the output of the overturn switch to inhibit water from moving toward the combustion chambers. The control device allows the engine to be restarted during a preset period of time after stopping the engine operation.
