The Martyr CMT20 is a small teardrop anode in zinc, the metal the maker names for salt water. It bolts on, with holes spaced 1-1/4 in to 1-5/16 in center to center. It measures about 3-1/2 in long, 1-3/4 in wide and 1-3/8 in high. The maker lists aluminum for brackish water and magnesium for fresh water, so this zinc version is the salt water choice.
Our take
Zinc is the metal Martyr names for salt water, with aluminum and magnesium given for brackish and fresh, so check your water before choosing this one. At about 3-1/2 in long with 1-1/4 in to 1-5/16 in hole spacing, it is a compact bolt-on.
