ABSTRACT:
A marine propulsion device comprising a transom unit adapted to be mounted on a marine vehicle, a swivel support pivotally mounted on the transom unit for vertical tilting movement about a horizontal tilt axis, a lower unit pivotally steerable relative to the swivel support about a vertical steering axis, and a steering mechanism for pivoting the lower unit about the steering axis. The steering mechanism comprises a first pulley rotatably mounted on the transom unit, a steering arm for rotating the first pulley, and cables for connecting the first pulley to the lower unit so that the lower unit pivots in response to rotation of the first pulley. The steering mechanism also includes a second pulley and the lower unit is pivotally steerable relative to the swivel support by rotatably mounting the second pulley on the swivel support and by fixedly attaching the lower unit to the second pulley. The cables are connected to the lower unit by connecting the cables to the second pulley. The steering mechanism also includes guides between the first pulley and the second pulley through which the cables extend for maintaining the relative distance along the cables between the first pulley and the second pulley when the swivel support pivots about the tilt axis.
