Description
The Yamaha 6E5-11325-00-00 is a genuine OEM internal zinc engine anode designed to protect internal engine components such as the cylinder head, crankcase, and cooling passages from galvanic corrosion. It acts as a sacrificial element, corroding in place of critical engine metals to extend engine life.
This anode is widely used across Yamaha outboards and is essential for maintaining proper corrosion protection in saltwater environments.

Parts Desk Insight
This is one of Yamaha’s most widely used internal anodes. Because it protects areas you can’t see, it’s often overlooked—but when it’s gone, corrosion starts internally. Replacing it regularly is one of the cheapest ways to prevent major engine damage.
