ABSTRACT:
A sealing device for use with a drive shaft of a water vessel. The sealing device comprises a housing for a seal and bearing, a compression ring, a lip seal flange attachment and a diaphragm for tracking the movement of the shaft. The diaphragm is made of a resilient, flexible material and is operatively connected to the seal housing. In operation, the diaphragm tracks the motion of the drive shaft so that the drive shaft may move freely in the hull of the vessel. The diaphragm allows the rigid seal housing to also move in response to any axial, lateral or circular-axial (wobble-like) movement of the shaft so that a constant seal around the shaft is provided.
