Secure your outboard motor against theft with high-quality McGard security locks. Simply replace one of the existing nuts with a McGard security nut. Our outboard motor locks are made entirely of high-quality, hardened stainless steel. If someone attempts to force them open with burglary tools, a loose sleeve will rotate, but the lock itself will remain secure, protecting your motor from theft.
The proven sleeve design effectively prevents the use of burglary tools and offers reliable protection for your valuable investment. The locks are available for virtually all common outboard motor makes and models.
