    Lock washer???

    The guy dad just bought his boat from did not have a lock washer behind the prop. Should we add one or is just the nut enough? Motor is an '08 250 pro xs. Thanks.

    No locking tab washer used with the Torquemaster Gearcase.

    Larger washer first, then bellville (cone-shaped) washer, and finally mid-thickness washer (followed by locknut).

    Assuming you have the HD hub kit pictured below NO you do not need a lock washer, correct torque is 55 ft. lbs.
