Yamaha - Internal Crankcase Anode Kit - F200, F225, F250 3.3L Corrosion Protection - 2006–2008

Overview

On the 3.3L F200, F225, and F250 models from 2006 to 2008, these internal anodes are working every time the engine is in the water to keep corrosion in check. They’re designed to take the hit before it reaches critical internal components, especially in saltwater environments. As they wear down, that protection starts to fade, leaving the engine exposed. Replacing them along with the grommets is simple preventative maintenance that helps keep your motor protected and running strong.
