MG Duff Mercruiser Bravo Alpha 1 Gen 2 Engine Anode Kit

These new boxed anode kits ensure that you get all you need for servicing your engines anodes.

Anodes protect the various metal components ( propeller, shaft, keel, rudder, engine) from deterioration caused by galvanic corrosion when your boat’s hull is submerged.

Galvanic corrosion is the deterioration of metal, which occurs when dissimilar metals are joined together by a conductor in an electrically conductive fluid – the least noble metal (the anode) dissolves while the most noble metal (the cathode) remains protected.

Anodes deterioration must be monitored carefully and replaced every year when doing the antifouling/launching or when the anode is 75% dissolved.

The choice of anode depends of the nature of the water:
Saltwater = Zinc Anodes
Freshwater = Magnesium Anodes
Brackish Water = Aluminium Anodes
