摘要： A steering system for a vessel includes an electric actuator that generates power to rotate a steering wheel, a transmitting mechanism that transmits a rotation of the electric actuator to the steering wheel, and a power supply controller that supplies electric power to the electric actuator according to an input signal that is not based on a rotation of the steering wheel.

摘要： A trim-tilt device includes a first electric motor electrically connected to a power source and tilts an outboard motor body in an up-and-down direction. A steering device includes a second electric motor electrically connected to the power source. The steering device turns the outboard motor body in a right-and-left direction. A fuel pump is electrically connected to the power source, and supplies fuel to an engine. A controller limits an inrush current into the first electric motor using a PWM control for a predetermined period of time from a starting time point of an input current into the first electric motor.

摘要： A steering assist unit for a tiller handle of an outboard motor includes a housing, a pump, and a hydraulic actuator. The housing is connected to the tiller handle. The pump is housed in the housing. The hydraulic actuator is driven by hydraulic fluid from the pump. The hydraulic actuator applies an assist steering force to the outboard motor.

摘要： A steering device for an outboard motor is rotatably supported on a hull of a boat about a steering axis. The steering device includes a tiller handle, an actuator, and a linkage. The tiller handle is attached to the outboard motor. The actuator rotates the tiller handle about the steering axis. The link linkage is movably disposed between a connection position and a blocking position. The linkage transmits the driving force from the actuator to the tiller handle at the connection position. The linkage shuts off the transmission of the driving force from the actuator to the tiller handle at the blocking position.

摘要： An inner circumferential surface of a clamp bracket is open at an inner side surface of the clamp bracket. At least a portion of a movable body is surrounded by the inner circumferential surface in a side view. The movable body is movable to a plurality of positions including a position above a swivel bracket and a position inside a space surrounded by the inner circumferential surface of the clamp bracket. A steering shaft rotates around a steering axis along with movement of the movable body.

摘要： An outboard motor includes an outboard motor body, a first support mounted on a boat body, a second support that rotatably supports the outboard motor body, a linkage that couples the first support and the second support to each other such that the second support is movable in a vertical direction and rotatable with respect to the first support, a first drive that rotates the second support coupled to the first support through the linkage with respect to the first support while moving the second support in the vertical direction with respect to the first support, and a second drive that rotates the outboard motor body with respect to the second support.

摘要： A steering for a marine propulsion unit adjusts at least one of a required steering speed and a required steering torque such that the required steering speed and the required steering torque fall within an output region when the required steering speed and the required steering torque are outside the output region, sets a target steering angle according to the adjusted required steering speed and required steering torque, and sets the target steering angle according to a rotation angle of a steering wheel when the required steering speed and the required steering torque are within the output region.
