Heavy Duty Shaft Anodes

Our range of heavy duty 'through bolt' zinc shaft anodes range in size from 2 inches to 4 inches. See the chart for specifications. Anodes are an inexpensive form of galvanic protection and are generally attached to the hull (and also marine structures), but they are also installed on outboards and stern legs, and work to counteract the effect of having dissimilar metals in contact with seawater (or freshwater), which causes galvanic corrosion.
