Tecnoseal Mercruiser Engine Zinc Kit Alpha One Gen 1

A zinc anode protects the iron and other metal parts of a boat from corrosion. The anode is installed below the waterline on the areas that you want to protect.

Corrosion occurs electrochemically, so to speak. When different metals are in contact with each other, they act like an electric battery: the metals form the terminals of the battery and the salt water connects these terminals. In such a combination , the baser metal always corrodes first . Zinc is a baser metal than iron, stainless steel, copper, brass, etc., and therefore protects these metals.

Zinc anodes should be checked during each lift and replaced immediately if worn. The zinc anode is installed longitudinally in connection with the metal parts to be protected .

Note: The zinc anode must not be painted with boat primer , as the paint will prevent its function.
