More Information
Zinc Guard ZG77 Pear-Shaped Zinc Anodes are the reliable choice for safeguarding your boat from galvanic reactions in saltwater.
The ZG77 comes ready to fit, complete with a backing pad, nuts and washers.
When your hull is immersed in water, anodes protect the various metal components (propellor shaft, keel, rudder, engine) from the deterioration caused by galvanic corrosion.
Galvanic corrosion (also called electrolytic corrosion) is the deterioration of metal that occurs when dissimilar metals are joined together by a conductor in an electrically conductive fluid.
The least noble metal (the anode) dissolves, leaving the most noble metal (the cathode) protected.
Zinc is the correct anode metal for yacht protection in saltwater.
