Yamaha - Internal Crankcase Anode Kit - F75 Corrosion Protection - 2009–2014

Overview

On the 2009 to 2014 F75 models, these internal anodes are doing the kind of work you don’t see—but definitely need. They’re designed to take on corrosion before it reaches the engine’s internal metal surfaces, especially in saltwater use. Over time, they wear down, and once they’re gone, that protection disappears. Replacing the anodes and grommets as a set is a simple way to stay ahead of corrosion and keep your engine running strong.
