An outboard motor includes an outboard motor main body and a mount assembly to mount the outboard motor main body to a hull. The mount assembly includes a clamp bracket to be fixed to the hull, a swivel bracket to support the outboard motor main body, and a hydraulic cylinder. The swivel bracket is coupled to the clamp bracket through a tilt shaft and turnable around the tilt shaft. The hydraulic cylinder is located between the clamp bracket and the swivel bracket and is able to turn the swivel bracket around the tilt shaft with respect to the clamp bracket. The outboard motor includes a gas damper to damp an external force that acts in a telescopic direction of the hydraulic cylinder.

A suspension structure includes a clamp bracket attachable to a hull, a main load bearing portion to support an outboard motor body to mainly bear the weight of the outboard motor body, a tilt shaft, a coupling, and a cylinder to change a trim angle or a tilt angle of the outboard motor body. The coupling includes a first end rotatably supported by the tilt shaft, and a second end fixed to the main load bearing portion. The cylinder includes a first end supported by the clamp bracket at a position lower than the tilt shaft and rotatable about a first rotation shaft in an up-down direction, and a second end supporting the coupling and rotatable about a second rotation shaft in the up-down direction. The second rotation shaft is provided in or near the main load bearing portion.

A steering actuator is for steering an outboard marine engine about a steering axis. The steering actuator comprises a housing; a piston device that is disposed in the housing, wherein hydraulic actuation of the piston device causes the outboard marine engine to pivot about the steering axis; and a valve device that is disposed in the housing. The valve device controls a flow of a hydraulic fluid to move the piston device in a first piston direction and to move the piston device in an opposite, second piston direction. Movement of the piston device in the first piston direction causes the outboard marine engine to pivot in a first pivot direction and movement of the piston device in the second piston direction causes the outboard marine engine to pivot in an opposite, second pivot direction.

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.

A system for controlling a marine vessel comprises an input device for inputting an operator command, a sensor which senses and signals an engine function variable or a vessel dynamic variable, and a first structural element and a second structural element. The first structural element and the second structural element each control speed or direction of motion of the marine vessel, and the first structural element and the second structural element each affect the marine vessel dynamic variable. There is a controller which receives the operator command and the engine function variable or the vessel dynamic variable. The controller moves the first structural element and the second structural element based on the engine function variable or the vessel dynamic variable, after receiving the single operator command.

An outboard motor mount and side-mount accessory adapter to mount an outboard motor and an accessory to the transom of a boat wherein the outboard motor mount includes a transom mounting plate to secure the outboard motor mount to the transom and an adapter mounting plate extending outwardly from the transom mounting plate and wherein the side-mount accessory adapter includes a proximal side-mount adapter mounting plate coupled to the adapter mounting plate and a distal accessory mounting plate to support the accessory thereon.
