Abstract

In prior stern drive marine propulsion systems, power is transmitted through an arrangement of clutches, bevel gears and shafts to the propeller located below the water surface. This restricts the amount of torque which can be transmitted particularly for large commercial boats. The present invention therefore provides an outdrive designed to surpass the horsepower and torque limitations set by current state-of-the-art units. In order to meet these objectives the outdrive was designed to incorporate a multi-strand roller chain drive (40), replacing the conventional bevel gear arrangement. Using a chain drive in this application serves to increase durability of the outdriv e, while keeping the outer (43) casing very streamlined.
