McGard Outboard Lock-Johnson/Evinrude/Mercury/Yamaha Theft Protection for Outboard Motors.
Click Here for more information!
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. A free-spinning collar turns if attacked by gripping tools, protecting you against costly outboard motor theft and the resulting inconvenience.
