ABSTRACT:
Disclosed herein is a power steering system for a marine propulsion device having a propulsion unit movable around a generally vertical steering axis, the power steering system comprising a tilt tube for affording tilting movement of the propulsion unit around a tilt axis substantially transverse to the steering axis, a steering ram within the tilt tube for bi-directional movement relative to the tilt tube and having a projecting end, a power steering cylinder fixed relative to the tilt tube, a piston reciprocable within the power steering cylinder, a piston rod having an inner end connected to the piston and having an outer end extending from the steering cylinder, a spool valve assembly including a first member mounted to the outer end of the piston rod, and a second member reciprocably moveable relative to the first member, an elongate bell crank having a first end pivotally connected to the projecting end of the steering ram, having a second end pivotally connected to the second member and being pivotally connected between the first and second ends to the first member for movement relative to the first member, and linkage means coupled between the outer end of the piston rod and the propulsion unit for pivoting the propulsion unit around the steering axis in response to movement of the piston rod relative to the cylinder.
