Outboard Motor Locks
Theft Protection for Outboard Motors.
McGard outboard motor locks are designed to lock the outboard onto the transom of the boat. Simply replace one of the mounting nuts with a McGard locking nut. McGard outboard motor locks are identical in quality and construction to our stern drive locks. A free-spinning collar turns if attacked by gripping tools, protecting you against costly outboard motor theft and the resulting inconvenience.
