To have an electrolysis problem certain conditions must be present. You must have two different metals in contact with the water. All of our boats are made out of a single metal, so they don’t have this problem.

The only metals in contact with the water are the aluminium’s of the engine and the boat. Since the aluminium of the engine is “softer”, this is the metal that would be consumed by electrolysis. The sacrificial Anodes supplied with your engine will protect it, but should be watched and replaced as needed.

Additionally, we can place a large sacrificial zinc anode on the boat’s transom as a secondary protection.
