Overview

This head anode is one of those small parts doing serious work inside your engine. It’s designed to take the corrosion hit right at the cylinder head, protecting critical internal surfaces from electrolysis. If you’re running in saltwater or even mixed conditions, it doesn’t take long for these to start wearing down. Swapping it out during routine maintenance is a simple way to protect your powerhead and avoid bigger problems down the road.
