Important Compatibility Information

This anode does not fit every Yamaha 40–90 HP outboard.

Later Yamaha engines within the same horsepower range can use completely different bracket anodes.

Before ordering, please check:

Exact engine model
Engine year
Engine serial number
Original Yamaha part number
Existing anode dimensions and shape

If the part 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 confirm compatibility.
