Most boaters (especially sailors) are sensitive to the environment and use only Propylene Glycol Antifreeze
in the raw water sections of their boat's engine. Hopefully you do as well.
I always buy undiluted and mix it 50% with water in a five gallon bucket. A hose is then fed to the sea water strainer, which draws the solution into the engine after starting. As previously mentioned, I also shut down as soon as it's seen exiting from my wet exhaust.
