Marine Pencil Zincs & Anodes

Fisheries Supply is your premier supplier of marine pencil zincs in aluminum and zinc (for saltwater) or magnesium (for fresh water). Pencil zincs are typically used to protect engine heat exchangers from galvanic corrosion and can usually be found attached to a brass plug within the heat exchanger. They should be checked while doing annual engine maintenance and replaced if less than 50% of the anode remains. Shop for your magnesium pencil anode now and save or browse our wide selection of engine raw water pumps.
