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.

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.

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.
