Yamaha F9.9C / F15A Outboard Trim-Tab Anode

66M-45371-00 - Trim Tab Anode

The materials and build quality of a Yamaha engine means it's already highly resistant to corrosion. The addition of a self-sacrificing anode will improve this even further. As a first line of defence, an anode is meant to corrode instead of your engine. It can easily be replaced by another, thereby protecting the engine. However, high-quality Yamaha anodes are more durable than most of their competitors and will need to be changed less often, thereby maximising the protection of your engine.
