This Martyr shaft anode, CMX04AL, is made of aluminum and sized for a 1-1/8" shaft, with a 1-1/8" inside diameter. It measures 2-1/8" across the outside and 2-1/8" long. Aluminum is the metal the maker pairs with salt and brackish water, so that is the water this one is meant for.
Our take
Aluminum is the metal here, and it is matched to salt and brackish water, so it is a salt-side choice. The 1-1/8" ID against a 2-1/8" OD and length sets the shaft size and the room it takes.
