The Critical Importance of Timely Anode Replacement for Engines and Saildrives

February 3, 2025

Why Anodes Are Essential for Your Engine and Saildrive

Anodes play a crucial role in protecting your boat engine and saildrive from corrosion. In this article we explain why replacing anodes is so important, what to look for when choosing anodes and where to find them.

Why should you replace anodes?

Anodes are made of sacrificial metals such as zinc, aluminum or magnesium. These metals are less noble than the metals that make up the engine and saildrive, which is why they corrode first. This process prevents important parts such as the propeller shaft, saildrive and engine block from being attacked by electrolytic corrosion.

If anodes are not replaced in time, metal parts of the engine and saildrive can be damaged, which can lead to expensive repairs. Therefore, it is essential to regularly check the condition of your anodes and replace them in time.

What should you pay attention to when choosing anodes?

When choosing anodes there are a few important factors to consider:

Choice of material :
- Zinc : Suitable for salt water.
- Aluminum : Suitable for both salt and brackish water.
- Magnesium : Suitable for fresh water.
The right size and fit :
- Check your engine or saildrive manual to see which anodes are recommended.
- Preferably use anodes that are specifically designed for your type of engine or saildrive.
Regular check and replacement :
- Check the anodes at least once per season.
- Replace them once they are more than 50% consumed.
