| 摘要 |
The dual propeller surface drive propulsion system for boats is a combined propulsion and steering system for vessels with inboard engines comprising an enclosed thrust bearing assembly mounted to the transom of the vessel, a transom box mounted to the transom of the vessel that encompasses the thrust bearing assembly, an articulated outdrive pivotally connected to the transom box, a gearbox contained within the articulated outdrive, two counter rotating propeller shafts equipped with surface-piercing propellers and a steerable rudder system. Counter-rotating propellers reduce propeller-induced torque. By combining an articulated outdrive with a steerable rudder greater maneuverability of the vessel is achieved.
