Important Compatibility Warning
Yamaha uses different internal anodes depending on the engine model, year and serial number.
Please check:
-
Engine horsepower
-
Exact engine model
-
Engine serial number
-
Existing anode
-
Original Yamaha part number
Do not order by horsepower or appearance alone.
If the anode looks the same as yours, this does not always mean it is the correct part for your outboard.
If unsure, send us your engine model and serial number and we can help check compatibility.
