MG Duff MGD Series Egg Type Shaft Anode - Zinc

The MGD range of shaft anodes are known for their superior quality, and are particularly suited to vessels with high shaft speeds.

Building on the integral core bar design that controls wastage, ensuring the shaft anode remains secure, the MGD range now incorporates socket head (allen bolt) stainless steel fixings with captive nuts to ensure maximum reliability.

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.

Anode 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 or Aluminium Anodes
• Freshwater: Magnesium Anodes
• Brackish Water: Aluminium Anodes
