Propeller Anode MAX PROP MX-2

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 on the areas that need to be protected. It acts as a sacrificial shield and effectively prevents corrosion in the underwater metal parts of the boat.

Corrosion occurs electrochemically when dissimilar metals are in contact with each other. The combination of such metals acts like an electric battery, where the metals are the poles and the salt water connects them. In this situation, the more base metal always corrodes first. Zinc is a more base metal compared to, for example, iron, stainless steel, copper and brass, and therefore effectively protects more valuable metal parts.

Intended use

• Protection of underwater metal parts of a boat

• Protection of propeller shaft and other shaft structures

• Particularly suitable for seawater and brackish water use

Installation instructions

• The anode is always installed below the waterline.

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

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

• 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 regularly inspected and timely replaced zinc anode extends the life of the boat's metal parts and helps prevent damage caused by corrosion.
