Abstract: A control device, a control method, and a control program of a propeller for ship that enable the ship to move accurately in parallel are provided. When a joystick is tilted in a predetermined direction, a system controller performs a second control to make a ship move in parallel in accordance with corrected control parameters while correcting control parameters of outboard motors for moving the ship in the predetermined direction, on condition that wave height at a current position of the ship is equal to or higher than a threshold value, determines whether the control parameters are appropriate from a moving state of the ship when the ship is moved in accordance with the control parameters, on the condition that the wave height is lower than the threshold value, and rewrites the control parameters so that the ship moves in parallel when the control parameters are not appropriate.

Abstract: There is provided a boat maneuvering support device for a boat including an outboard motor, a power device which outputs a thrust force in a port-starboard direction, and a steering mechanism which changes a steering angle. The device includes a rotational speed detection unit which detects a rotational speed of a propeller of the outboard motor, and a control unit which controls a magnitude of the thrust force output by the power device. The control unit controls the magnitude of the thrust force output by the power device so as to change a balance between a magnitude of a first turning force which makes the boat turn by a thrust force of the outboard motor and a magnitude of a second turning force which makes the boat turn by the thrust force of the power device.

Abstract: In an apparatus for controlling a boat equipped with an outboard motor mounted on its stem and having an internal combustion engine, a propeller to be driven by the engine and a propeller pitch changer adapted to variably change a pitch of the propeller, an opening of a throttle valve installed at an air intake system of the engine and its change amount are detected, and based on the change amount of the detected opening of the throttle valve, it is determined whether or not the pitch of the propeller is to be changed through the propeller pitch changer.

Abstract: An outboard motor includes: an outboard motor body including a propeller driven by an internal combustion engine; a mounting portion configured to mount the outboard motor body to a hull so as to be movable relative to the hull; and an operation mechanism provided between the outboard motor body and the mounting portion and configured to adjust a relative position of the outboard motor body with respect to the hull. The operation mechanism is a link-type operation mechanism including a hydraulic cylinder as an actuator.

Abstract: An outboard motor is provided with: an engine cover in which a first outside air inlet port, an exhaust port, and second outside air inlet ports are formed; and a lower housing that is disposed below the engine cover. The engine cover is provided with a front guide and a rear guide that guide outside air, introduced respectively from the first outside air inlet port and the second outside air inlet ports into the engine cover, downward in the gravity direction.
