Which Material Should I Choose?

Zinc – Traditional choice for boats used mainly in saltwater.

Aluminium – Excellent general-purpose option, particularly for saltwater and brackish water.

Magnesium – Best suited to freshwater use due to its higher sacrificial activity.

Important: Magnesium anodes are generally not recommended for prolonged saltwater use.

IMPORTANT – Yamaha-Made Mariner Engines

This anode is specifically for selected Mariner outboards manufactured by Yamaha in Japan.

It is NOT suitable for every Mariner 20 HP, 25 HP, 28 HP or 30 HP engine.

Please check the engine model, serial number prefix and original anode before ordering.

Important Compatibility Warning

Please check:

Engine horsepower
Engine model
Serial number / prefix
Existing trim tab dimensions and shape
Original part number

If the anode looks the same as yours, this does not always mean it is the correct part for your outboard. Please double-check compatibility.
