Raw Water Cooling In Salt Water at Donald Cargill blog

Raw Water Cooling In Salt Water. Raw water refers to the water that the boat is floating in. Older gas engines are frequently raw water cooled, but some do have closed cooling (mine included). In the raw water system this scale is building up inside the engine’s water jacket and ports. This water is pumped through the engine, absorbing heat before being discharged overboard. At this point you are probably looking at replacing the. Salt will begin to precipitate out of seawater at approximately 148° f, forming deposits on engine cooling passages, which ultimately will. Salt water tends to build up a corrosive scale when the engine operates above 140°. There are two main ways engine manufacturers engineer the cooling system on a boat: Water is then usually exited through the exhaust and out the. With raw water cooling in salt the main problems people have is exhaust system related, the risers and manifolds will rust sooner than the. In contrast, the raw water cooling system, also known as a sea water cooling system, directly cools the engine with water from the surrounding environment. The raw water pump, also known as the seawater pump, is responsible for drawing in water from the surrounding body of water and. It makes no difference whether it is salt or fresh, both are used to cool the engine. When the scaling builds to the point that water flow is restricted the engine starts to overheat.
