Abstract
The present invention provides a lightweight and simply-configured watercraft of a jet-propulsion type that can maintain steering capability according to the cruising speed of the watercraft even when a throttle-close operation is performed and the amount of water ejected from a water jet pump is thereby reduced. When a throttle-close operation and a steering handle operation are detected, steering assist mode control according to the present invention is executed to increase the engine speed. The increasing speed of the engine speed is adjustably increased to subdue the rate of change between the cruising speed at the detection of the operations and the cruising speed to be changed by the control, and the watercraft can continue to turn smoothly under the control.
