A Martyr block anode with part number CM393023M, marked J/E in its name. It is made of magnesium. Martyr pairs magnesium with fresh water, with zinc for salt water and aluminum for brackish water. This one is the magnesium type, so it is the fresh water choice in that range.
Our take
The magnesium material decides where this block belongs. Martyr assigns magnesium to fresh water, so on a boat kept in salt or brackish water this is the wrong metal and one of the other two types in the range is the one to look for.
