Abstract
A jet-propelled watercraft capable of maintaining a propulsion force required for a turn made at the same time as closing of a throttle valve. The jet-propelled watercraft has an auxiliary intake valve and an ECU. The auxiliary intake valve in an intake pipe opens/closes an auxiliary intake passage to bypass a throttle valve. The ECU performs control such that an opening of the auxiliary intake valve in a state where the rotation speed of the engine is not lower than a threshold value is larger than the opening of the auxiliary intake valve in a state where the engine is idling. When in a state where the rotation speed is not lower than the threshold value, it is detected that the throttle valve is completely closed and that a steering mechanism has been turned by a prescribed angle or more, a current opening of the auxiliary intake valve is maintained.
