Description

The Yamaha 6P3-11325-00-00 is a genuine OEM internal zinc engine anode designed to protect critical internal engine components such as the cylinder head and crankcase cooling passages from galvanic corrosion. It acts as a sacrificial element, corroding first to prevent damage to more expensive engine metals.

This anode is commonly used across Yamaha high-horsepower outboards and is essential for maintaining long-term engine reliability in saltwater environments.
