Keep in mind, anything down below the waterline wants an anode or to be grounded to an anode! This features trim tabs and through-hulls. Trim tabs have specially developed anodes. As a result of-hulls might be electrically related by wire to an anode.
Hull anodes can be used to safeguard any electrically bonded accessories or to guard metallic-hulled boats. These are usually much larger than other anodes.
Zinc anodes operate effectively to protect aluminum hulls in saltwater. In freshwater, magnesium anodes get the job done a lot better than zinc for aluminum boats. But never ever use magnesium anodes on an aluminum hull in saltwater.
Propeller shaft anodes go round the stainless-steel shaft and bolt with each other on possibly facet on more info the shaft. This design is intended to attenuate drag and hold the shaft properly well balanced.
