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.
