Magnesium anodes are used only for freshwater. The alloy will react more rapidly if a magnesium boat anode is exposed or submerged in saltwater. It can also result in a different electrochemical reaction, which will cause the creation of hydrogen under the paint of the metal drive surface. In addition, you can benefit from a reduced loss rate due to lower circuit potential with a magnesium anode. The Sierra high-standard engine parts are well-designed to meet OEM specifications.
