Protect your boat hull in saltwater with a bolt-on sacrificial zinc hull anode. Hull anodes are best fitted close to the propeller to not disturb the flow of water. The voltage between the anode and the propeller should be low enough. In this case, the anode will corrode instead of the equipment. This way, the anode will not disturb the operation of the equipment while preventing electrolytic corrosion.

Sea Shield Marine uses a proprietary process that meets the highest standards. This means the purity of the metal is high, making it a better anode. This is why we sell Sea Shield Marine products with the best pricing and service.
