It is difficult to move forward/backward a water jet propulsion boat at very low speed through use of right and left operation elements each provided on a handle. In order to move the boat forward/backward at very low speed through a simple operation, under a state in which neutral operations have been carried out, an operation state of an engine is maintained in an idling state, and a movement position of a jet flow adjustment member including a deflector and a reverse bucket is controlled so as to adjust a difference between a “thrust generated by a forward jet flow component” and a “thrust generated by a backward jet flow component” of a jet flow divided into a forward jet flow and a backward jet flow by the jet flow adjustment member, based on an operation on a third operation element provided independently of the right and left operation elements.
