Double-acting hydraulic actuating cylinder, particularly for hydraulic steering devices of outboard marine engines. The cylinder is slidably mounted on at least one rod coaxial to the cylinder sealingly protruding from at least one head of the actuating cylinder and carrying a separating piston that divides the cylinder into two variable volume chambers, each one of such two chambers has an inlet/outlet for the hydraulic fluid, each connected to one of two inlets/outlets of the pump and a sealing head for the relative sliding between the cylinder and the rod, which sealing head is integral with the cylinder itself. The rod is provided to be connected to a fastening bracket to fasten the cylinder to the engine, in a not slidable manner and in such a way as to allow the relative rotation of the engine with respect to the transom along an axis parallel to the axis of the rod. The rod has at least one flattened surface to be grasped by a tool having at least one corresponding flat engagement surface for engaging said flattened surface.

When a cable-actuated power steering system is used with an outboard motor tiltably supported on a motor mounting pod of a pontoon boat, interference between a valve actuator housing on the end of a cylinder ram of a hydraulic cylinder unit and a side wall of pod is avoided by offsetting the cylinder toward one side wall of the pod so that the actuator housing can move through its full range without interfering with the opposite side wall, and connecting the cable-activated steering rod to a lever on top of the actuator through an L-shaped secondary link that has a first part extending laterally from an end of the steering rod and a second part extending from the first part to the lever in a direction opposite to the direction in which the cylinder ram extends from the cylinder.

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.

A watercraft propulsion system includes first and second propulsion devices attachable to a hull asymmetrically with respect to an anteroposterior center line of the hull, a lateral movement command generator to generate a first lateral movement command and a second lateral movement command to laterally move the hull rightward and leftward, and a controller. The controller includes a memory to store first and second lateral movement thrust ratios indicating ratios between a forward propulsive force and a reverse propulsive force in a first lateral movement control and a second lateral movement control. When one of the first and second lateral movement thrust ratios is set in a calibration mode, the controller is configured or programmed to set an initial value of the other of the first and second lateral movement thrust ratios to an inverse of the one of the first and second lateral movement thrust ratios.

The present disclosure relates to a houseboat assembly formed from a cabin assembly secured to a hull assembly. In some version of the houseboat assembly, one or both of the cabin assembly and the hull assembly may be formed in accordance with a boat type and/or a floor plan. The boat type and/or floor plan may be selected by a customer. The cabin assembly may be formed at a first location and the hull assembly may be formed at a second location. The cabin assembly and hull assembly may then be transported to a third location. At the third location, the cabin assembly may be secured to the hull assembly to form the cabin assembly at the third location. The third location may be requested or specified by the customer.

A vertically adjustable jack plate configured to attach an outboard motor (or analogous device) to the transom of a marine vessel. A transom bracket is provided for connection to the vessel. A motor mounting plate is connected to the transom bracket. A lift jack vertically adjusts the position of the motor mounting plate with respect to the transom bracket. The lift jack incorporates a drive shaft that is used to vary an amount of extension or the lift jack. A handle is provided on the drive shaft. In operation, the user must preferably engage the handle to the drive shaft in order to turn the drive shaft. In a preferred embodiment the user must push the handle inward toward the lift jack in order to engage the handle to the drive shaft.

A control assembly for a watercraft is presented comprising a housing defining at least one passage adapted to receive a steering column therethrough, a lever being pivotally connected to the housing about a first axis, the first axis being offset from the at least one passage, the lever being adapted to be disposed between a steering wheel of the watercraft and a dashboard of the watercraft, and an electronic motor control system operatively connected to the lever, the electronic motor control system producing signals operative to control a speed of a motor in response to the lever being rotated about the first axis. A watercraft including a control assembly is also disclosed.
