Yamaha Trim Tab Anode | 67C-45371-00-00

Overview

The Yamaha 67C-45371-00-00 Trim Tab Anode is a genuine OEM sacrificial anode designed to help protect the lower unit of your Yamaha outboard engine from corrosion while also assisting with steering balance. Mounted on the lower unit behind the propeller, the trim tab anode helps counteract propeller torque, reducing steering pull and improving overall handling.

This trim tab is made from corrosion-resistant metal that sacrifices itself over time to protect critical engine components from electrolysis and galvanic corrosion. As the anode gradually deteriorates, it shields the more expensive metal parts of the lower unit. Replacing worn anodes as part of routine maintenance helps extend the life of your outboard and maintain optimal performance.

FAQ

Q: What does a trim tab anode do?
A: It helps balance steering torque from the propeller and protects the lower unit from corrosion.

Q: Why is the anode considered sacrificial?
A: The anode corrodes first, protecting the engine’s metal components from galvanic corrosion.

Q: How often should a trim tab anode be replaced?
A: Typically when about half of the material has worn away or during routine annual maintenance.

Q: Does this part affect steering?
A: Yes. Proper trim tab adjustment helps reduce steering pull caused by propeller torque.

Q: Is this a genuine Yamaha part?
A: Yes. The 67C-45371-00-00 is an OEM Yamaha trim tab anode designed for select 4-stroke outboards.
