A propeller assembly is provided for mounting on a rotatable propeller shaft of a marine vehicle. The propeller assembly includes a central hub mounted on the propeller shaft for rotation therewith. A generally tubular propeller housing is slidable on the central hub for rotational movement with the propeller shaft. The propeller housing includes an inner surface having a shoulder formed therein. A locking ring is mounted on the propeller shaft. The locking ring includes an outer rim for engaging the shoulder and preventing removal of the propeller housing from the central hub. A stop member may also be provided to limit movement between the propeller housing and the central hub.
