A shaft extending along a longitudinal axis has fluid channels that increase and decrease pressure in chambers formed between the interior ends of curved pistons and adjacent closed ends of curved chambers within which the pistons reciprocate as the chamber pressure increases and decreases. The chambers and pistons are in separate cylinder block segments extending outward from opposing sides of the shaft. Each segment may have two sides extending along radial planes and joined by a curved outer surface. Pistons may be provided in pairs and have an interior piston end of each piston in a different cavity in different segments. Exterior ends of each piston in a pair of pistons are connected to a piston connector that extends inwardly from a housing so the housing rotates with the pistons.

Hydraulic rotary actuator

A directional nozzle for the jet output that is attached to a control cable system. This cable turns the directional nozzle, which causes the trust of the jet output to turn the boat. Thus, the boat can be steered without having to turn the entire motor. Two different mechanisms are disclosed that enable the steering. The first is a tiller system that operates much like the traditional tiller on an outboard motor. However, unlike those tillers, this tiller operates the directional nozzle and does not turn the entire motor. The second mechanism is a bicycle handlebar system that is placed forward of the motor, much like a traditional wheel. The handlebar system, when combined with the directional nozzle system, produces faster steering response without the effort required to turn the wheel to make large sweeping turns.

Jet powered steering system for small boat outboard motors

A joystick controller for modified steering system for boats with outboard motors. The system uses a directional nozzle for the jet output that is attached to a control cable system. This cable turns the directional nozzle, which causes the trust of the jet output to turn the boat. Thus, the boat can be steered without having to turn the entire motor. The system also has a reversing cup to change direction. The system uses a joystick that connects to a set of actuators, which in turn, connect to the directional nozzle, reverse cup and throttle. In this way, the joystick can control the movement of the boat in any direction. The joystick can be used with a conventional motor as well.
