Yamaha - Internal Crankcase Anode Kit - F75LA Corrosion Protection - All LA Models

Overview

On the F75LA models, these internal anodes are there to take the corrosion hit before the inside of the engine does. It’s one of those maintenance items that’s easy to forget, but in saltwater especially, they matter more than most people realize. Once they’re worn down, the protection starts disappearing and internal components can become the next target. Replacing the anodes and grommets together is simple preventative maintenance that helps keep the engine protected and running strong.
