Why Sacrificial Anodes Are Essential
In marine environments, different metals create galvanic cells that cause corrosion. Aluminum anodes have a lower electrical potential than your engine components, causing them to corrode first and protect your valuable parts. Regular anode replacement is the most cost-effective way to prevent expensive engine damage.
