    Description
    A Spare ZD77 Pear Shape Anode.

    Hole centres 200mm. Anode weight 2.2kg


    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
