ABSTRACT:
A marine propulsion system for high performance power boats is provided which includes a propellor shaft that extends parallel to the surface and thus enables a "surfacing" operation wherein each of the propellor blades or discs extend out of the water during a portion of the rotational period thereof. The system includes a universal joint which joins the propellor shaft to an inclined connecting member connected to a reduction gear unit. The universal joint is located in an upper support housing mounted to the underside of a recessed area at the stern of the hull while the propellor shaft is mounted by a thrust bearing assembly and a further, spaced bearing assembly within a lower support housing affixed to the upper housing. The propellor assembly includes a thrust sleeve joined to the propellor shaft by a series of spaced weldments which serve in transmitting thrust to the sleeve.
