A marine vessel includes a plurality of turning mechanisms (12) provided respectively in correspondence to a plurality of outboard motors (3S, 3C, 3P). Each turning mechanism (12) includes a hydraulic pump (101), an electric motor (102S, 102C, 102P) to drive the hydraulic pump (101), a hydraulic cylinder (103) including two cylinder chambers (107, 108) partitioned by a piston, and a normally-closed bypass valve (115) to put the two cylinder chambers (107, 108) of the hydraulic cylinder (103) into communication with each other. Upon judging that there is a malfunction in the turning angle control of at least one of the outboard motors, a main ECU displays on a display, an operation guidance screen to urge a marine vessel operator to open the bypass valve (115) of the turning mechanism (12) corresponding to the malfunctioning outboard motor. Also, the main ECU keeps a power transmission between an engine (69) and a propeller (90) in the malfunctioning outboard motor an an interrupted state. |
