Vane steering system for marine drives

摘要

A marine drive has a high aspect ratio, counterbalanced vane on the propulsion unit for generating hydrodynamic torque when rotated. Control cables fastened to a bar on the vane post extend to the rear end of a lever mounted on the steering arm of the marine drive. The forward end of the lever receives the control rod of the boat steering mechanism. Movement of the control rod moves the lever, pulling one or the other control cable and rotating the vane. The lever is so mounted on the steering arm that movements of the control rod are magnified in operating the control cables. Vane rotation may be used to counteract propeller torque components causing course deviations to the boat and to provide torque for turning the marine drive.
