A marine vessel maneuvering system includes a controller configured or programmed to perform a propulsion reverse direction control to change a direction of a propulsive force of a propulsion generator to a reverse direction when a user operates an operator to turn a marine vessel either counterclockwise or clockwise and the marine vessel has been previously turned either clockwise or counterclockwise, respectively.

A sensor detects a shape of a shore arrival location and a positional relationship of the shore arrival location and a boat body and outputs environment information indicating the shape of the shore arrival location and the positional relationship. A controller receives the environment information and generates an instruction signal to control a propulsion device to cause the boat body to move toward the shore arrival position set based on the environment information and to push the boat body to the shore arrival location.

An actuator for imparting steering movement to a tiller of a propulsion unit of a marine vessel comprises an absolute position sensor operable to sense a steering position and a relative position sensor operable to sense a position of the motor. A steering control unit calibrates the relative position sensor based on a signal of the absolute position sensor. Calibration of the relative position sensor based on a signal of the absolute position sensor initializes an accumulative position which accumulates a relative position as the actuator moves over time.

An operation apparatus configured to operate a ship propulsion machine includes: a remote control device including a holder and an operation lever swingably supported, and configured to perform a shift switching operation of the ship propulsion machine and an operation of increasing/decreasing a rotation speed of a power source of the ship propulsion machine; a gauge device including a display device and configured to display information regarding the ship propulsion machine including information indicating a shift position of the ship propulsion machine and the rotation speed of the power source; and a case to which the remote control device and the gauge device are each attached, and which integrates the remote control device and the gauge device. In the case, the remote control device and the gauge device are disposed adjacently to each other in a front-rear direction of the ship.

A device for fastening a steering actuator cylinder to an outboard marine motor includes a fastening rod insertable inside the outboard marine motor and having ends each inserted inside a corresponding housing seat obtained in a terminal element, so that the fastening rod has a relative rotation with respect to the terminal elements, which are further fastened to the steering cylinder. The outboard motor is integral with the fastening rod, so that the outboard motor can oscillate around the longitudinal axis of the fastening rod. At least one insulating element is interposed between each end of the fastening rod and the corresponding housing seat, the insulating element is configured to at least partially surround the surface of each end.
