Why Aluminum Anodes?

Aluminum anodes are the standard choice for most modern outboards because they provide dependable corrosion protection in salt, brackish, and freshwater environments. Unlike zinc, which can become less effective in freshwater, aluminum remains active and continues protecting your engine. This makes aluminum the most reliable option for boaters operating in mixed-water conditions.
