Yamaha – Cylinder Head Anode Grommet | Engine Corrosion Protection Component | 67F-11328-00-00

Overview

Small sealing parts inside a Yamaha outboard often do more work than people realize. The Yamaha Cylinder Head Anode Grommet 67F-11328-00-00 helps secure and seal the internal engine anode so it can properly protect the cooling passages from corrosion. Without a good grommet, water can seep where it shouldn’t and the anode may not sit correctly in the cylinder head. Replacing worn grommets during service helps keep the corrosion protection system working the way Yamaha designed it.

Key Features

• Secure Anode Mounting Seal – Holds the engine anode firmly in place while sealing the mounting point in the cylinder head.

• OEM Yamaha Fitment – Manufactured to Yamaha specifications for proper sealing and dependable installation.

• Cooling System Protection – Helps prevent water intrusion and maintains the integrity of the engine’s corrosion protection system.

• Durable Marine Grade Material – Built to withstand heat cycles, water exposure, and harsh marine environments.

• Ideal for Corrosion System Service – Commonly replaced during anode inspection or cooling system maintenance.

Engine & Boat Compatibility

FAQ

Q: What does a cylinder head anode grommet do?
A: It seals the mounting location for the engine anode and helps keep the anode properly positioned inside the cylinder head.

Q: Should this grommet be replaced during anode service?
A: Many technicians replace it whenever the anode is serviced to ensure a proper seal.

Q: Can a worn grommet cause water leaks?
A: Yes. If the seal deteriorates, water may leak around the anode mounting point.

Q: Why are engine anodes important for Yamaha outboards?
A: They protect internal metal components from corrosion caused by electrolysis.

Q: Is this part exposed to heat and water inside the engine?
A: Yes. It sits within the cooling system area and must withstand constant temperature changes and water exposure.
