Gori Tire Anode15-16.5"

Zinc anode for protecting boat metal parts

A zinc anode protects the iron and other metal parts of a boat from corrosion. The anode is installed below the waterline on the objects that you want to protect. Corrosion occurs electrochemically when different metals are in contact with each other and water acts as a conductive medium. In this case, the metals behave like an electric battery, where the more base metal corrodes first.

Zinc is a more base metal than iron, stainless steel, copper, and brass, which is why it protects these materials from corrosion by acting as a sacrificial metal.

Important installation and operating instructions

• Zinc anodes should be checked every time the boat is lifted.

• The anode must be replaced immediately if it is clearly worn.

• The zinc anode is installed longitudinally in connection with the metal parts to be protected.

• The zinc anode must not be painted with boat primer.

• The shaft anode is attached to the propeller shaft as close as possible to the shaft support.

A properly installed and timely replaced zinc anode is one of the most important ways to prevent damage to the metal parts of a boat and extend their service life.
