In a marine cooling system, the terms "raw water" and "fresh water" refer to two different sources of fluids used to cool the engine.
Raw water is water that is drawn directly from the surrounding environment, such as a lake, river, or ocean. This water is typically used as a cooling medium to remove heat from the engine, and then discharged back into the environment. Raw water can contain a variety of impurities, such as salt, sand, and debris, which can cause corrosion and damage to the engine if not properly treated or filtered inbound to the heat exchanger.
“Fresh water” is a colloquial term in the marine industry for glycol or antifreeze. This “Fresh water”is typically used in a closed-loop system, where it circulates through a heat exchanger and the engine to remove heat from the engine, and then continues to circulate. This system is commonly used in stern drive and inboard or inboard/outboard applications. It is preferred in saltwater environments, as it helps to prevent corrosion of the engine.
In summary, raw water is water taken from the environment and used to cool the engine, while “fresh water” is a marine industry term for glycol/antifreeze.
