  • Patent number: 10494073
    Abstract: 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.
