Marine Pencil Zincs & Anodes

Protect Your Marine Engine with Pencil Anodes

Fisheries Supply sells marine pencil anodes made of aluminum, zinc, and magnesium for saltwater and freshwater use. Pencil anodes, also called pencil zincs or engine anodes, are important for protecting your boat engine from corrosion.

What are Pencil Anodes?

Pencil zincs are sacrificial anodes designed to protect specific components of your marine engine, particularly the heat exchangers. These anodes typically attach to a brass plug within the heat exchanger and act as a barrier against corrosion.

The Importance of Regular Maintenance

Proper maintenance is essential to ensure the longevity and optimal performance of your marine engine. During your annual engine maintenance routine, it is crucial to inspect the pencil zinc anode. If less than 50% of the anode remains, you should replace it to maintain effective protection against galvanic corrosion.

At Fisheries Supply, we offer several types of pencil zincs:
