Why Replace Your Anode?
Sacrificial anodes are designed to corrode instead of expensive metal components on your outboard.
Regular inspection and replacement of worn anodes helps protect:
- Gearbox / lower unit
- Propeller area
- Underwater metal components
- Outboard components susceptible to galvanic corrosion
Anodes should be replaced when significantly worn to maintain effective protection.
Important – Please Check Compatibility
Please do not order by horsepower or appearance alone.
Yamaha used different trim tab anodes across engines with the same horsepower.
Before ordering, please check:
- Engine model
- Engine year
- Existing trim tab anode
- Original Yamaha part number
If the anode looks the same as yours, this does not always mean it is the correct one for your outboard.
If you are unsure, please send us your engine model and serial number before purchasing and our technical team will be happy to check compatibility.
