Do you know the importance of replacing your outdrive anodes?
It's very important and often overlooked service needed to prevent corrosion. Why do we need to change anodes and what is the importance of doing so? Plain and simple...corrosion. When dissimilar metals are in contact with one another and immersed in water, this destructive process begins. The type of water in which they operate can accelerate this process. That white, crusty build-up you may see developing on your outdrive, gimbal housing or prop is galvanic corrosion eating your outdrive. Changing anodes when needed can drastically slow this process.
Anodes come in different types of metal such as magnesium for freshwater or aluminum and zinc for salt water. They "sacrifice" themselves because they are more active, or easily consumed by this type of corrosion. In some more severe cases, sanding, priming, and repainting becomes necessary to prevent the eventual replacement of damaged areas. If an issue is present during the summerizing process of your boat, we will call you with an estimate.
