Product Details

Camp Zinc Pencils for marine engines contain pure zinc with brass hex plugs. These anodes typically thread into a port on the raw seawater side of a heat exchanger.

Routine replacement of pencil anodes will greatly extend the life of marine engine coolant systems. The majority of inboard and stern drive engines will benefit from a fresh set of zinc anodes. Pencil zincs provide cathodic protection when in contact with seawater.
