Bolt-On Aluminum Sacrificial Anode for Hull of Boat
Bolt-on aluminum hull anodes provide best cathodic protection in fresh or brackish water. Choose the right Sea Shield Marine anode to ensure the longevity of your equipment. We provide quality anodes that meet the highest Mil-Spec standards.
Hull anodes should be fitted close to the propeller, but not disturb the flow of water. Check to make sure that the voltage between the anode and the propeller is low enough. In this case, the anode will corrode instead of the equipment. Also, the anode will not disturb the operation of the equipment.
