ABSTRACT:
A marine propulsion device comprising a propulsion unit pivotable about a first steering axis to steer a marine vehicle, a trim tab mounted on the propulsion unit and pivotable about a second steering axis for assisting in steering the vehicle, and a hydraulic sensing arrangement for sensing torque on the propulsion unit relative to the first steering axis to pivot the trim tab in response to the torque. The device also includes steering mechanism for pivoting the propulsion unit about the first steering axis to steer the vehicle. The steering mechanism includes a steering member connected to the propulsion unit, and operable to move the steering member to pivot the propulsion unit. The steering mechanism operable to move the steering member includes a push-pull cable with a core and a flexible housing. The hydraulic sensing arrangement permits lost motion between the flexible housing and the steering member and the hydraulic sensing arrangement senses torque on the propulsion unit relative to the first steering axis by movement of the flexible housing relative to the steering member.
