McGard Lower Unit Lock anti-theft device

The McGard Lower Unit Lock protects the lower unit of your outboard motor against theft. This high-quality anti-theft device was specifically designed for Yamaha outboard engines. Simply replace the original screw with the McGard security screw and protect your valuable lower unit from theft.

The McGard Lower Unit Lock is constructed entirely from high-quality, hardened stainless steel. This proven design features a sleeve that rotates when an attempt is made to force the lock open with tools. The lock itself, however, remains fixed, providing maximum protection.
