The Martyr MerCruiser Bravo III Prop Nut Zinc Anode (2004-Present) is designed to help protect your sterndrive from galvanic corrosion in saltwater environments. Built as a prop nut anode for Bravo III applications, this zinc anode helps sacrificially absorb corrosive activity before it can damage more expensive underwater metals. For boaters running a MerCruiser Bravo III drive, replacing worn anodes is a simple but important part of routine maintenance.
