Fresh Water Cooling System Introduction Although there is an abundance of free sea water available‚ marine diesel engines do not use it directly to keep the hottest parts of the engine cool. This is because of the corrosion which would be caused in the cooling water spaces‚ and the salts which would be deposited on the cooling surfaces interfering with the heat flow. Instead‚ the water circulated around the engine is fresh water which is then itself cooled using sea water. This fresh water is
