PROBLEM TO BE SOLVED: To provide a jet propulsion boat capable of turning a hull with less skill than that required in a conventional technique, by reducing a lateral centrifugal force when the hull is turned during high speed navigation, and lessening a load to a rider.SOLUTION: A jet propulsion boat comprises: a hull; a jet propulsion machine propelling the hull; an engine driving the jet propulsion machine; and an ECU. When a manipulated variable of a first accelerator manipulation unit is greater than that of a second accelerator manipulation unit in S1, the ECU determines that a deceleration operation is executed. When a navigation state of the hull is a high speed navigation state and the hull is in a state of turning, the ECU sets an upper limit to a rotational speed of the engine to a first predetermined value. When the navigation state of the hull is the high speed navigation state and the hull is not in the state of turning, the ECU sets the upper limit to the rotational speed of the engine to a second predetermined value greater than the first predetermined value. The ECU determines a position of a reverse bucket on the basis of the manipulated variable of the first accelerator manipulation unit and that of the second accelerator manipulation unit. |
