About Shaft Anodes
Are you looking to protect your shaft from corrosion? Look no further than using a shaft anode. They are designed to make complete contact with the shaft with a clamp insert to ensure a tight fit through the entire life of the anode. Only the highest quality and purest alloy is used to construct these anodes which means you can be sure that these anodes meet or exceeds US Military Specification. With iboats vast selection, you can be sure the exact shaft anode you need is available for any type of water that you will be boating in: zinc for freshwater, magnesium for saltwater, and aluminum for salt and brackish water. Selecting the appropriate anode will help prevent corrosion and give a long life of cathodic protection. These anodes are available to fit any size of shaft, no madder the diameter or length you need.
