摘要： A controller is configured or programmed to obtain at least either of a pitch angle of a watercraft and an angular velocity of the pitch angle, obtain a present thrust of an outboard motor, and set a target thrust of the outboard motor based on the present thrust 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 a drive source such that a thrust of the outboard motor becomes the target thrust.

摘要： A posture control system for a hull includes a movable posture control plate. An outboard motor is attached to the hull and is movable with respect to the hull. A controller is configured or programmed to control movement of the posture control plate and movement of the outboard motor so as to control the posture of the hull.

摘要： An outboard motor includes an engine, a propeller shaft that rotates together with a propeller and extends in a forward-rearward direction, and a lower case that houses the propeller shaft. The lower case includes a front case and a rear case separate from the front case and positioned rearward of the front case, and the front case and the rear case are assembled to each other.

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 is fed upward from a gear chamber, includes a first feed passage, extending 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, and a second feed passage, extending from the first upstream passage to the connection passage while bypassing the spiral passage via a bypass passage. The bypass passage is positioned farther outward than the spiral passage in a radial direction of the driveshaft. A diameter of a cross section of the bypass passage that is orthogonal or substantially orthogonal to a center line of the driveshaft is smaller than a maximum diameter of the driveshaft.

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 navigation control system includes an obstacle detector on a hull to detect a distance from a hull to an obstacle on a water surface and a position of the obstacle, a thruster on the hull to generate a propulsive force, a steering to steer the thruster to right and left sides of the hull, and a controller configured or programmed to perform a control to determine an obstacle avoidance route based on a route function including at least an indicator of a lateral acceleration that acts on the hull during steering of the thruster when the obstacle is detected by the obstacle detector.

摘要： In a boat including a hull, when the hull is moved laterally based on an output from the outboard motor, the hull rolls, which may cause discomfort to a user or passengers. To compensate for this, a lateral movement control method for the boat including the hull and the outboard motor includes generating a propulsion force to laterally move the hull with the output of the outboard motor, and executing a roll reduction process to reduce a roll angle of the hull at a time of laterally moving the hull.

摘要： A system includes an outboard motor, an 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 trim-up direction or a trim-down direction as a trim 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 actuator to cause the outboard motor to perform a trim motion in the trim direction, and to set a duration of the trim motion to be different between when the outboard motor is caused to perform the trim motion in the trim-up direction and when the outboard motor is caused to perform the trim motion in the trim-down direction.

摘要： An outboard motor includes an engine, a drive shaft, and a shift shaft disposed forward of the drive shaft. The shift shaft includes a first shift shaft that extends in an upward-downward direction, a second shift shaft disposed below the first shift shaft and spaced apart from and rearward of the first shift shaft, the second shift shaft extending in the upward-downward direction, and a shift force transmission to transmit, to the second shift shaft, a shift force applied to the first shift shaft.

摘要： An engine includes a crankshaft extending in a vertical direction. A drive shaft is connected to the crankshaft and coaxial with the crankshaft. A water intake passage is connected to the engine. A water pump is connected to the water intake passage. The water pump includes a pump shaft. The pump shaft is eccentrically mounted with respect to the drive shaft and parallel or substantially parallel to the drive shaft. The pump shaft rotates according to rotation of the drive shaft.
