Shaft Zinc Anode 30mm, narrow model

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 shield and prevents corrosion damage to the boat's underwater metal parts.

Corrosion occurs electrochemically when different metals are in contact with each other and water acts as a conductor. In a combination of such metals, the base metal corrodes first. Zinc is a base metal compared to, for example, iron, stainless steel, copper and brass, which makes it effective in protecting more valuable metal parts.

Intended use

• Protection of the propeller shaft and related metal parts

• Underwater metal structures of a boat

• For use in fresh and salt water

Installation

• The anode is 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 anode must not be painted with primer or other paint.

Maintenance and inspection

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

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

• A worn anode no longer protects metal parts effectively

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