Abstract
A power boat propulsion system installed in a power boat having a waterway in the stern, an engine on the inside, and a shaft coupled to the engine and inserted through the waterway, includes a barrel-like impeller duct fixedly fastened to the rear outlet of the waterway, an impeller pivoted to the inside of the impeller duct and connected to the shaft for synchronous rotation with the shaft, a stator mounted inside the impeller duct and adapted for supporting a rear end of the shaft, and a rudder mounted inside the impeller duct near a rear outlet of the impeller duct. The rudder has top and bottom sides thereof pivoted to the impeller duct for deflection leftwards and rightwards.
Claims4
