McGard: Stern Drive Locks

Simply replace one of the stern drive mounting nuts with a McGard lock. Stern drive locks are fully machined from high quality stainless steel and through-hardened. This proven design features a free-spinning collar that turns if attacked by gripping tools without loosening the lock. Give yourself the best protection available against stern drive theft.  Ask for McGard Marin Locks by name.STERN DRIVE UNITTHREADDRIVEMerCruiserî Alpha, Bravo I-III (Incl.
