ABSTRACT:
The marine propulsion device includes a propulsion unit mounted for tilting movement about a generally horizontal tilt axis and for pivotal steering movement about a vertical steering axis, and a power steering system adapted to operably connect an actuator to the propulsion for increasing the steering force applied to the propulsion unit by the actuator. The power steering system is wholly supported on the propulsion unit and includes a hydraulic cylinder-piston assembly having an axis extending in fixed parallel rotation to the tilt axis and including a cylinder, a piston mounted in the cylinder, and an extendable and retractable piston rod connected to the piston, and a control valve connected to a source of pressurized hydraulic fluid for selectively controlling the flow of hydraulic fluid to and from the opposite sides of the piston to extend and retract the piston rod. The control valve includes a valve member and valve housing rotatably and axially movable relative to each other. The valve member is connected to the actuator and the valve housing is connected to the piston rod for common movement and is connected to the propulsion unit to affect steering movement thereof in response to movement of the actuator.
