Marine Zincs and Anodes
Zincs and Anodes for Boats
Help important boat components last longer with our collection of boat anodes. Often called boat zincs since this is one of the common materials used for them on saltwater anodes, they have one goal: sacrifice themselves to corrosion and impacts so other underwater parts may live. These reactive metal accessories attract the brunt of corrosion and impacts so they don’t affect far more crucial components. Of course, once the anodes are used up, you must swap them immediately. Marine Parts Source has a huge catalog of boat zinc anode replacements designed to let crucial systems maintain their performance.
Active Underwater Boat Protection
Many types of boat and yacht anodes are available for serious boaters. Browse complete outboard and sterndrive anode kits with the accessories you need to do spring preparation. If you need to replace individual anodes, do so with shaft, rudder, hull, pencil, thruster and propeller shaft anodes. We even carry anodes to protect water tanks and bow thrusters. Along with saltwater marine zincs, there are aluminum boat anodes for brackish water and magnesium anodes for freshwater applications.
Marine Parts Source is an authorized distributor of the leading OEM and aftermarket boat zinc brands, including Martyr, Volvo Penta, Bombardier, Quicksilver and Suzuki. It’s easy to find the correct anodes — just select a category or enter the part number in the search bar. Many anodes are in stock and ready to ship the same business day.
