McGard MARINE ANTI-THEFT LOCKS

Protect your outboard motor with high quality McGard anti-theft locks. Simply replace one of the fitted nuts with a McGard security nut. An attempt to break this open causes only a loose sleeve to rotate, but the lock remains securely in place, and your motor is protected against theft.
