<p>HYDRO TORQUE SKEG FOIL Disclosed herein is a marine propulsion device including a downwardly extending propulsion leg, the lower end of said propulsion leg including a gear case, a drive shaft housed in the propulsion leg, a propeller shaft located in the gear case, and a propeller mounted on the propeller shaft, rotary operation of said marine propulsion device producing a steering torque on the propulsion leg. The propulsion leg also includes a skeg extending downwardly from the gear case, the rearward edge of the skeg comprising a foil for producing a torque on the propulsion leg opposite to the torque produced by rotary operation of the marine propulsion device.</p> |
