Description

The Yamaha 6G8-11325-00-00 is a genuine OEM zinc crankcase anode designed to protect internal engine components from galvanic corrosion. Installed inside the engine block or cooling passages, this anode sacrifices itself to prevent corrosion damage to critical internal parts.

Zinc construction makes it ideal for saltwater applications, where corrosion activity is highest.

Parts Desk Insight

This is one of the most overlooked maintenance items on Yamaha outboards. Because it’s internal, failure often goes unnoticed—until corrosion starts damaging the engine from the inside. Replacing these regularly is cheap insurance against major cooling system repairs.
