Specifications

Material
Magnesium

This is a Martyr horseshoe anode, listed as CM392462M and made of magnesium. Magnesium is the metal the maker pairs with fresh water. That makes it a match for boats that stay in fresh water. The same guide gives salt water to zinc, so this is not the choice there. Check the shape against your old anode before fitting.

Our take

Magnesium is what Martyr says to use in fresh water, and this horseshoe is a magnesium one. On a boat kept in fresh water that matches the material guide, but the same guide gives salt water to zinc, so leave it off a salt-water boat.
