To provide a small-sized watercraft equipped with an actuator enabling continuous steering of the boat even if a throttle is turned off.
This watercraft is equipped with a water-jet pump P, a steering apparatus for shifting jetting direction, and a steering throttle-actuating means, which, in the case of a throttle lever being turned off, enables continuation of steering function with the engine-throttle turned to the open-position at a prescribed angle under prescribed conditions. An actuator 31 actuating the engine throttle from the off-position to the open-position at a prescribed angle is provided with a motor 31m energized at a prescribed amperage under control of a control device 31c, a reduction mechanism 31r for reducing a revolution speed of the motor, and an output shaft 31S rotated at a speed reduced by the reduction mechanism. The actuator 31 allows the throttle of the engine to return to off-position by spring force, when the energization is shut off by control of the control device.
