My cooling system (raw water side) was completely "cleaned" off the engine in early 2017. Just today, I replaced my gear oil cooler with a new one that has zincs (the old one does not). The saltwater side of my old gear cooler was "spotless", however, I freshwater flush my engine as often as I can, and store the engine with a solution of "salt away" inside for the winter. I have an oil pan heater that runs throughout the winter and freezing temps are rare here in southern (coastal) BC.
I am a big believer in the benefits of freshwater flushing, and it only takes about 10 minutes to do it.
Nanaimo, BC
