No-Feedback Steering System for Marine Drives Abstract of the Disclosure A steering system for a steerable marine drive has a fluid filled cylinder with the housing connected to the boat and the piston connected to the steering arm of the marine drive. The piston contains valves operated by the control cable con- nected to the steering wheel of the boat. When the valves are closed, the piston, and hence the marine drive, is locked in position. Propeller torque or other forces imposed on the marine drive are trans- ferred to the boat rather than to the control cable and the steering wheel. To steer the marine drive, the control cable initially opens the valves in the piston, unlocking the marine drive. Thereafter it moves the marine drive to the desired position. A lost motion mechanism, including that used in a vane steering system, may be utilized for this purpose. Alternately, the piston may lock the lost motion mechanism rather than the marine drive, to prevent the transmission of forces to the steering wheel.
