How To Fit Shaft AnodesHow To Fit Shaft Anodes

Aluminium Shaft Collar Anodes

Typically located near the propeller of the boat, shaft collar anodes are used to prevent the propeller from sliding along the shaft. The collar anode works in the same way as a regular shaft anode; it attracts and neutralizes any stray electrical current that may be present in the water, protecting the shaft and the collar from corrosion.

Aluminium shaft anodes are a great option for those who keep their vessels in salt and fresh water, as unlike zinc shaft collar anodes and magnesium shaft collar anodes, aluminium anodes are suitable for use in both types of water.
