Abstract
Abstract Disclosed herein is a marine steering system comprising a marine propulsion device including a hollow tilt pin connecting a swivel bracket to a boat attachment bracket to provide for swinging movement of the swivel bracket about the axis of the tilt pin, a king pin connecting a propulsion unit to the swivel bracket for swinging movement about a steering axis transverse to the tilt pin axis, a rotary member extending, at least in part, in the hollow tilt pin and operatively connected to the propulsion unit for swinging the propulsion unit about the steering axis in response to rotation of the rotary member, a steering device comprising a housing adapted to be attached to the boat hull at a location spaced from the marine propulsion device, a steering wheel rotatably mounted on the housing, and an output member rotatably mounted on the housing and drivingly connected to the steering wheel, and a flexible cable including an outer sheath connected to the housing and to the marine propulsion device and an inner rotary element connected to the steering device output member and to the rotary member in the hollow tilt pin to thereby cause rotary movement of the rotary member in response to rotation of the steering wheel and thereby to swing the propulsion unit about the steering axis. The rotary member in the tilt pin includes a threaded portion and there is located coaxially within the tilt pin a second member including a nut engaged with the threaded portion, and a linkage connecting the second member to the propulsion unit for preventing swinging movement of the second member about the tilt pin axis independently of the propulsion unit and for swinging the propulsion unit about the steering axis in response to movement of the second member axially of the tilt pin incident to rotation of the rotary member.
