Why Aluminum Anodes?
Mercury outboards are factory-equipped with aluminum anodes. Aluminum anodes provide consistent cathodic protection across salt, brackish, and freshwater environments, while zinc anodes can become inactive in low-salinity water and may void manufacturer warranties. This kit ensures proper protection while maintaining OEM compliance.
