No postal feelings here, but do tend to grit my teeth over the use of the term raw water. Raw milk comes straight from the animal and has not been homogenized or pasteurized. Ditto raw honey and other food forms. Unsure here what is meant by raw water, since water from the ocean is well sea water.

It would seem to me that salt water from the ocean would best be defined by the use of the term sea water. Lake water, without ocean water contamination, would best be defined as fresh water, or is that also raw water? It becomes brackish when there is a blend of sea water with fresh. Then of course you have other forms of water terms, such as filtered water, boiled water, hot water, steaming water, under water, over water, heavy water, and so on.

Maybe all water is raw until we alter its form much like we do with the foods mentioned above. Sleep would befall much quicker if someone could enlighten me and relieve this angst, eh?

Not sure what "altering it's form" would entail.
Technically it's always just water with varying contaminants. Anything else and it's no longer water. (super oxygenated water anyone ? LOL)

Wouldn't any water taken very recently from it's source be fresh water ?
Fresh Seawater ? Fresh Softwater ? Fresh sewage water ?

I vote for Raw Water= "water that hasn't been heated" Like Raw meat pre BBQ. hehe

Raw water makes sense to me. It differentiates the water you pull from outside the boat to cool the cooling water inside the boat that cools the engine.

It means it hasn’t had any processing. In computer land - data input by the users is Raw Data and once it undergoes some processing by the computer it is said to be cooked data. Of course raw data exists outside of computers people who deal with number talk about raw data all the time. Only computer nerds cook their data

Water from the sea. If you have a sea water pump to cool the antifreeze does it magically change to a river water pump or lake water pump when you go thru the locks and visit lake Washington? Calling it a raw water pump it keeps the same name in each environment.

Raw water is plain water from outside the boat. Nothing has been added to it or done to it save, straining out weeds and what not. Cooling water is water with additives, i.e., antifreeze, ergo, it is not raw.

Raw water and seawater are essentially interchangeable terms.

I believe that one who experiences angst over the various terms used to define water outside the boats hull should possibly need a soft reboot to shake out all those problematic synopsis which are the cause for angst in the first place....... :poke:

:plus: I believe the good doctor prescribes more time on the water sailing. Those of us stuck in the frozen north still shoveling snow have an excuse. What else could cause the long discussion about egg storage on another thread. :what:

Raw water makes sense to me. It differentiates...
I have a friend on Lake Michigan, same boat, essentially same engine. We have had this "conversation" for a while. I finally "convinced" him just because of the word Les used: differentiates. As in engineering, specificity helps a lot. We have two pumps on our engines: raw (outside) and fresh (coolant).

How could that water possibly be fresh after it has been round and round thousands of times?
How do you have a civil war?

@Stu Jackson, the so called freshwater pump should not be call this as it is not water being pumped, its glycol being circulated not water. While you could use water is a pinch, it certainly is not recommended. So there you have it.....:poke:

By the calendar it's not supposed to be winter but I have yet to change to a spring jacket as it's just to d#$% cold out there.

Hmm... what is well sea water? Isn't well water supposed to be fresh? I have heard of sea water intrusion, so maybe the sea water that intrudes into a fresh water well is well sea water. Or do you mean sea water that is not sick?

From Wikipedia: "Raw water is natural water found in the environment that has not been treated and does not have any of its minerals, ions, particles, bacteria, or parasites removed. Raw water includes rainwater, ground water, water from infiltration wells, and water from bodies like lakes and rivers." I hope that we can agree to accept this definition and move on to more important considerations.

But here on the Great Lakes we sail on fresh water......

Wikipedia, just another opinion source. Based on their opinion there is no such thing as sea water, fresh water or brackish water. Then Merriam Webster defines sea water as water in or from the sea. I like that definition. Makes more sense to me. Moreover Merriam Webster defines fresh water as water that is not salty especially when considered as a natural resource. Besides, pumps do not define the type of water; it just pumps. Angst now gone.:thumbup:
