Why Aluminum Anodes?
Mercury and Mercruiser outdrives are factory-equipped with aluminum anodes because they provide reliable protection across salt, brackish, and freshwater environments. Unlike zinc, which can become inactive in freshwater, aluminum continues to perform. Using zinc anodes on Mercury or Mercruiser drives may also void your manufacturer warranty, making aluminum the correct and compliant choice.
