摘要： The present invention provides a lightweight and simply-configured watercraft of a jet-propulsive type that can maintain steering capability in a way adapted to forward movement and rearward movement of the watercraft even when throttle-close operation is performed and the amount of water ejected from a water jet pump is thereby reduced. During forward movement, when the throttle-close operation and steering operation of a steering handle are detected and an engine speed is between an idling speed and a predetermined engine speed, the engine speed is temporarily increased. During rearward movement, when the engine speed is the idling speed, the engine speed is temporarily increased in the same way. The engine speed is increased by changing a fuel injection timing of a fuel injection system, a fuel injection amount, and/or an ignition timing of an ignition system of the engine.
