The Martyr CMC09 is a zinc collar anode with a 2 inch inside diameter. It measures 3-1/2 inch across the outside and 1-3/8 inch long. Martyr lists zinc for salt water and magnesium for fresh water, so this zinc one is the salt water choice. Check that your shaft is 2 inch before you choose it.
Our take
The 2 inch inside diameter is the first thing to check, because it has to agree with your shaft. At 1-3/8 inch long it is a slim collar, and being zinc it is the one Martyr lists for salt water rather than fresh.
