Stern drive lock
Antitheft protection for MerCruiser, OMC, Yamaha, and Volvo stern drives
Simply replace one of the fitted nuts with a McGard security nut. Our stern drive locks are made completely of high quality, fully hardened stainless steel. This tried and tested design features a sleeve that rotates when an attempt is made to force open the lock. The lock itself though remains fixed. Give your customers the best antitheft protection for stern drives.
