Duplicates the bonding system protecting the outside metals on your boat, this now protects the inside of the engine in the same manner. Has a large diameter zinc installed in this housing and a grounding wire lug that allows a wire to run to the block or wherever, making an exact copy of your exterior bonding system. You are adding zinc protection to your engine. If you have a zinc in your heat exchanger, great, but what about everything else in contact with raw water, such as your risers, etc.
