Outboard Motor Locks

Theft Protection for Outboard Motors.

McGuard outboard motor locks are designed to lock the bolt that holds the outboard motor onto the boat’s transom. Simply replace one of the mounting nuts with a McGuard locking nut. McGuard 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 against costly outboard motor theft.
