Magnesium Shaft Collar Anodes
If you sail in fresh water, you'll need a Magnesium shaft collar anode, as there is lower open circuit potential in fresh water. In addition, unlike zinc shaft collar anodes and aluminium shaft collar anodes, magnesium anodes react rapidly when exposed to seawater, which is why they should only be used in fresh water.
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.
