ABSTRACT:
Several embodiments of improved sealing arrangements for sealingly engaging an auxiliary power unit and the portion of the hull of a water craft that defines an opening through which the power unit drive extends. In each embodiment the seal has an opening that is sized to pass the power unit and an arrangement is provided for forcing the seal into sealing engagement with the power unit. In some embodiments two axially spaced seals are provided and an arrangement is incorporated for limiting the degree of relative movement by the power unit and the hull. In one embodiment a water sensor is positioned in the area between the two spaced seals for detecting failure of one of the seals. The support for the sensor is such that it may be removed and inserted along with the power unit without damage to the seal.
