摘要： A marine propulsion system includes a controller configured or programmed to perform a marine vessel traveling direction control such that a traveling direction of a marine vessel is changed to a predetermined angle equal to or greater than a first angle with respect to a traveling direction of waves toward the marine vessel when the traveling direction of the marine vessel is less than the first angle with respect to the traveling direction of the waves toward the marine vessel.

摘要： A marine vessel maneuvering system includes a controller configured or programmed to perform a water entry determination control to determine whether or not water behind a hull that rises above a water surface due to deceleration of the hull may enter the hull when the hull is decelerating.

摘要： A marine vessel includes a hull, left and right propulsion devices attached to a stern of the hull, left and right drive units to change a rotation angle of the left and right propulsion devices about left and right tilt shafts, and to set an angle at which a position of a lower portion of the left and right propulsion devices becomes highest as a maximum rotation angle, left and right lift mechanisms to change a vertical position of the left and right propulsion devices with respect to the hull, and a controller configured or programmed to function as a judging unit to judge whether or not a displacement in a roll direction of the hull has occurred, and a control unit to control the left and right drive units and the left and right lift mechanisms.

摘要： A steering control apparatus for a marine vessel that is able to automatically reduce chine walk includes a processor to obtain behavior information on a hull, including one or more of a behavior relating to a shift of the hull in a roll direction, a shift of the hull in a yaw direction, a shift of the hull in crosswise direction, a steering load, and a helm operation load. When judging that one or more conditions to change a steering mode to a counter steering mode are satisfied, the processor changes the steering mode to the counter steering mode. In the counter steering mode, the processor controls steering of the marine vessel by performing counter steering so as to reduce at least some of one or more of the behaviors of the hull based on the obtained behavior information.

摘要： When a shift member is in a first position, a first clutch couples a second drive shaft to a first drive shaft. When the shift member is in the first position, a second clutch decouples a first gear from the first drive shaft. When the shift member is in the first position, a third clutch decouples a second gear from the second drive shaft.

摘要： A system includes an outboard motor including a lift actuator, a pitch angle sensor, a lift position sensor, and a controller configured or programmed to obtain at least either of a pitch angle of a watercraft and an angular velocity of the pitch angle. The controller is configured or programmed to obtain a lift position of the outboard motor, and controller selectively set either a lift-up direction or a lift-down direction as a lift direction based on the lift position of the outboard motor and at least either of the pitch angle of the watercraft and the angular velocity of the pitch angle. The controller is configured or programmed to control the lift actuator to cause the outboard motor to perform a lift motion in the lift direction.

摘要： A system includes an outboard motor, a lift actuator, a sensor, and a controller. The sensor detects motion information indicating an up-and-down directional motion of a bow of a watercraft. The controller is configured or programmed to selectively set either a lift-up direction or a lift-down direction as a lift direction in accordance with the up-and-down directional motion of the bow based on the motion information. The controller is configured or programmed to control the lift actuator to cause the outboard motor to perform the lift motion in the lift direction, and set a duration of the lift motion to be different between when the outboard motor is caused to perform the lift motion in the lift-up direction and when the outboard motor is caused to perform the lift motion in the lift-down direction.

摘要： In an outboard motor, a feed passage, through which a lubricating oil that flows upward from a gear mechanism due to rotation of the gear mechanism, extends upward from a gear chamber and includes a first feed passage that extends from the gear chamber to a connection passage via a first upstream passage, a spiral passage, and an interior of an upper bearing, in that order. The feed passage further includes a second feed passage that extends from the gear chamber to the return passage while bypassing the spiral passage via a bypass passage. The bypass passage includes two ends spaced apart in a circumferential direction of the driveshaft and is disposed around the spiral passage.

摘要： An apparatus for judging presence or absence of an abnormality of a marine vessel includes a controller configured or programmed to function as an estimating unit to estimate a marine vessel speed and a pitch angle of a hull of the marine vessel based on a propulsion force of a marine vessel propulsion device and an attitude of the marine vessel propulsion device and a judging unit, and a measuring unit to measure an actual marine vessel speed and an actual pitch angle. The judging unit judges the presence or absence of the abnormality based on at least one of a comparison result between the estimated marine vessel speed estimated by the estimating unit and the actual marine vessel speed measured by the measuring unit or a comparison result between the estimated pitch angle estimated by the estimating unit and the actual pitch angle measured by the measuring unit.

摘要： A system includes an outboard motor, an actuator, a pitch angle sensor, a trim angle sensor, and a controller to obtain at least either of a pitch angle of a watercraft and an angular velocity of the pitch angle, and to obtain a trim angle of the outboard motor. The controller is configured or programmed to selectively set either a trim-up direction or a trim-down direction as a trim direction based on the trim angle of the outboard motor and at least either of the pitch angle of the watercraft and the angular velocity of the pitch angle. The controller is configured or programmed to control the actuator to cause the outboard motor to perform a trim motion in the trim direction.
