摘要： A control system for an outboard motor is provided which enables safe navigation over a shoal. A control system for an outboard motor including a propeller includes: a trim angle adjustment motor for changing the attitude of the outboard motor with respect to a watercraft; and a controller configured to selectively implement first control that operates the trim angle adjustment motor and controls the vertical position of the propeller to a first position, and second control that operates the trim angle adjustment motor and controls the vertical position of the propeller to a second position closer to a water surface than the first position. The controller acquires information on the depth of water a predetermined distance ahead in the travel direction of the watercraft, and determines which of the first control and the second control is implemented, on the basis of at least the information on the depth of water.

摘要： A control device for a propelling system of a vessel that can support a safe sailing of the vessel while reducing the load, of a steersman by executing automatic sailing control on the vessel when the vessel enters or approaches a specific water area where the sailing is limited. When determining that a hull stays within the specific water area in a state where a revolution speed and a rotational direction of a propeller and a posture of an outboard engine are controlled based on a signal inputted from a controlling device, an ECU of the outboard engine switches the sailing of the hull to an automatic sailing where the revolution speed and rotational direction of the propeller and the posture of the outboard engine are controlled without the intervention of the controlling device.

摘要： In an apparatus for controlling a boat equipped with an outboard motor mounted on its stern 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.

摘要： Constant-speed-travel-apparatus controlling prime-mover so that mobile-body mounted with the prime-mover travels at constant-speed, includes: function-operation-member being instructed activation of speed-maintaining-function of the mobile-body in response to operation by operator; first-speed-operation-member being instructed the travel-speed of the mobile-body in accordance with operation-amount by the operator; second-speed-operation-member being instructed change of the travel-speed by predetermined amount in response to operation by the operator in state where activation of the speed-maintaining-function has been instructed through the function-operation-member; and electronic-control-unit controlling output of the prime-mover based on the operation-amount of the first-speed-operation-member and number of times of operation of the second-speed-operation-member so that the mobile-body travels at constant-speed in the state. The electronic-control-unit deactivates the speed-maintaining-function and controls the output of the prime-mover based on the travel-speed instructed through the first-speed-operation-member when the operation-amount of the first-speed-operation-member exceeds predetermined operation-amount in the state.

摘要： An air intake passage structure includes an outer cover forming an outer wall of an outboard motor, an inner cover disposed inside the outer cover, a first intake port formed in the outer cover, a second intake port formed in the inner cover, an air introduction chamber formed between the outer cover and the inner cover; and an air passage formed inside the outer cover. The air passage includes a first passage part on an upper side of the air introduction chamber, and a second passage part extending downward from the first passage part. The air introduction chamber includes a side portion communicating with the first intake port, and a top portion communicating with the first passage part through an opening formed in the partition wall.

摘要： An outboard motor comprises an engine and a cover that covers the periphery of the engine. The cover includes an outer cover that defines an outer appearance and an inner cover that covers the engine inside the outer cover. The outer cover comprises an outer side division structure that can be divided into a plurality of parts, and the inner cover has a structural part providing access to the engine.

摘要： 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.

摘要： 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.
