Shaft anode zinc, narrow model

Shaft anode for propeller shaft

A zinc anode suitable for the propeller shaft, which protects the boat's iron and other metal parts from corrosion. The anode acts as a sacrificial shield and prevents corrosion in the boat's underwater metal parts.

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

Intended use

• Propeller shaft protection against corrosion

• Protection of underwater metal parts of a boat

• Suitable for shaft-driven boats

Installation

• The anode is installed below the waterline

• Attached to the propeller shaft as close as possible to the shaft support

• 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 immediately if it is clearly worn.

• 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 of your boat and helps prevent costly corrosion damage.
