Abstract
A control unit is provided for increasing the number of engine revolutions per minute to a predetermined number of revolutions per minute when the throttle is closed and when the engine has been rotated for more than a prescribed time period at more than a prescribed number of revolutions per minute, and the throttle has been opened for more than a prescribed time period at more than a prescribed opening. The control unit increases the number of engine revolutions per minute to a predetermined number of revolutions per minute irrespective of the throttle and maintains the same for a predetermined retention time when the steering handle is turned to the left or the right by more than a prescribed angle. The time to start controlling the number of engine revolutions per minute may be delayed by providing a delay time for delaying the time to start controlling the engine revolutions. The number of engine revolutions per minute may be controlled after the hull is underwater. As a consequence, the amount of sideslip of the jet propulsion boat can be improved. In addition, since the control unit for increasing the number of engine revolutions per minute to a predetermined number of revolutions per minute irrespective of the throttle and maintaining the same for a predetermined retention time is provided, the quantity of jet water stream is secured. As a result, the steering of the jet propulsion boat is improved.
