1. An in-line power steering system for a marine vehicle comprising a propulsion unit pivotal about a steering axis, steering means for applying torque to said propulsion unit to effect steering movement thereof about said steering axis and including an operator actuable steering helm and a steering member connected to said propulsion unit;

  • power steering assist means having a reciprocating mechanical output force and operably connected to, and operably interposed between, said steering helm and said propulsion unit and mounted remote from said propulsion unit;

    a first actuable steering means operably connected (a) to said steering helm and actuated in response to steering actuation at said steering helm and (b) to said power steering assist means to effect actuating input to said power steering assist means upon actuation at said steering helm; and

    a second actuable steering means for accepting said mechanical output force and operably connected to said power steering assist means and to said steering member for overcoming torque on said propulsion unit relative to said steering axis in response to actuation of said second actuable steering means, said second actuable steering means providing actuable output transmitted from said power steering assist means to effect common movement of said steering member in response to steering actuation of said steering helm to pivot said propulsion unit about said steering axis.
