Shaft Zinc Anode

Shaft anode for propeller shaft

A zinc anode suitable for the propeller shaft that protects the boat's iron and other metal parts from corrosion. The anode acts as a sacrificial protection and effectively slows down corrosion in the boat's underwater metal parts.

Corrosion occurs electrochemically when different metals are in contact with each other. In this situation, the metals act like an electric battery, with water connecting the terminals. In such a combination of metals, the more base metal always corrodes first. Zinc is a more base metal compared to, for example, iron, stainless steel, copper and brass, so it effectively protects more valuable metal parts.

Intended use

• Propeller shaft protection against corrosion

• Protection of underwater metal parts of a boat

• Suitable for boats with shaft drive

Installation

• The anode is always installed below the waterline.

• Attach a shaft support as close as possible to the propeller shaft.

• Installed longitudinally in connection with the metal parts to be protected

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

Maintenance and inspection

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

• The anode must be replaced without fail if it is clearly worn.

• A worn anode no longer provides sufficient protection for metal parts

A properly installed and regularly replaced shaft anode extends the life of the propeller shaft and other metal parts of the boat and helps prevent costly corrosion damage.
