Abstract
A sealing system for a drive shaft extending through the hull of a vessel, the outboard end of the shaft being coupled to a propeller and the inboard end to the transmission of a marine engine turning the propeller. The system includes a bearing surrounding the shaft and an elastomeric lip seal coaxial with the shaft mounted adjacent one end of the bearing to prevent water from leaking into the vessel. The system is installed by passing the inboard end of the shaft through the bearing and the seal. Prior to such installation a protector sleeve is telescoped into the lip seal to shield its inner surface and thereby prevent damage thereto by sharp edges on the inboard end of the shaft, the sleeve having a brim which then rests against the end of the bearing. Upon completion of the installation, the sleeve is pulled by its brim out of the seal and is then ripped off the shaft.
