Zinc anode for protecting metal parts of a boat

A zinc anode protects the iron and other metal parts of a boat from corrosion. The anode is installed below the waterline in the areas that you want to protect. The zinc anode acts as a sacrificial metal and prevents damage to more valuable metal parts.

Corrosion occurs electrochemically when dissimilar metals come into contact with each other in water. They form an electrical pair, with the baser metal corroding first. Zinc is a baser metal than iron, stainless steel, copper and brass, so it corrodes instead.

Installation and use

• Installed below the waterline

• Attached longitudinally to the metal parts to be protected

• Do not paint with boat primer

Maintenance

• To be checked every time the boat is lifted

• Replace immediately if the anode is clearly worn.

A zinc anode is an important part of boat maintenance and helps to significantly extend the life of 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 metal parts that you want to protect.

Corrosion occurs electrochemically . When different metals are in contact with each other, they form an electrical battery: the metals act as the terminals of the battery and the water acts as the conductor. In this combination , the baser metal always corrodes first . Zinc is a baser metal than iron, stainless steel, copper, brass, etc., and therefore protects these structures from corrosion.

Zinc anodes should be inspected every time the boat is lifted and replaced immediately if they are clearly worn. The anode is installed longitudinally in connection with the metal part to be protected .

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

A zinc anode is an essential part of boat maintenance and helps to significantly extend the life of 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 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.

The function and operation of the zinc anode

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 need to be protected, such as drive gears, propeller shafts and other metal structures.

Corrosion occurs electrochemically . When different metals are in contact with each other and the environment is water, they form a kind of electric battery:

• metals act as battery terminals

• salt water (or fresh water) acts as an electrolyte

In such a combination , the baser metal always corrodes first . Zinc is a more base metal than iron, stainless steel, copper or brass, so it sacrifices itself and protects the other metal parts.

Installation and maintenance

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

• A worn anode must be replaced immediately.

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

• The zinc anode must not be painted , not even with boat primer, as painting will prevent its function.
