Why Aluminum Anodes?

Mercury and Mercruiser drives are factory-equipped with aluminum anodes. Aluminum provides reliable cathodic protection across salt, brackish, and freshwater environments, while zinc anodes can become ineffective in low-salinity water and may void manufacturer warranties. This kit ensures proper bonding and long-term corrosion protection while maintaining OEM compliance.
