Product Overview : 

Anodes provide cathodic protection in varying marine environments such as salt water, freshwater, and brackish water. Our sacrificial anodes conform to the highest Mil-Spec standards and come in a variety of shapes and sizes. Depending on the type of metal and water we offer zinc, aluminum, and magnesium galvanic anodes for all of your underwater cathodic protection needs.

Marine engines are typically composed of varying metals and alloys that wear out from rust and corrosion at different rates. To lower the rate of corrosion to improve the longevity of the marine engine, zinc rods and engine anodes will be used.

Commercial liners, cargo ships, private water vessels, maritime structures and shore equipment that are exposed to saltwater elements need corrosion protection to prevent untimely failure of engine components. Using Zinc Engine Yamaha Anode 801114 can allow equipment that is under heavy use to keep going to complete maritime operations. Many marine engines are fitted with zinc pencil engine anodes to help protect against internal corrosion. Some engines use specially shaped engine anodes, while others use standard pencil engine anodes.

Installing this Engine Cooling System Anode 01114 on engine block allows you to increase the longevity of your engine. Our engine anodes also protect heat exchangers for corrosion problems.

Key Features

  • Provides cathodic protection to the engine and ancillaries
  • Meets or exceeds US Military Specification (MIL-A-18001K)
  • For use in Salt Water


The anode must be in direct contact with the metal it protects : never paint around an anode or the anode itself.

When Should Anodes Be Replaced ?

Anodes deterioration rate may fluctuate according to the mooring area, water salinity, PH and temperature, potential electrical failure on board, and of course, the quality of the anodes themselves.

A good benchmark for replacement is when the anode is 70-80 % dissolved. We recommend to replace anodes every year when doing the boat antifouling/launching. In all cases, anodes deterioration should always be watched carefully together with the condition of the metal parts they protect. On the opposite, anodes may dissolve quickly if they are bad quality or if there is an electrical failure on.
