ABSTRACT:
A multi-layered sleeve bearing supports the propeller shaft of a propeller-driven water craft, the layered sleeves comprising an outer fixed master housing, an intermediate removable bearing housing, and an innermost bearing sleeve press-fitted in the removable bearing housing, such that when the bearing sleeve is worn past use, it may be replaced under water by removing the propeller from its shaft and sliding the bearing housing along with the worn bearing sleeve off of the shaft, taking the bearing housing above water and replacing the bearing sleeve within the bearing housing, and then replacing the bearing housing within the master housing under water. The procedure avoids the removal of rudder shaft or rudder as well as the necessity of dry docking the craft.
