Yanmar 2GM 20(F): Raw or Fresh Water Cooled version. How can I tell?
For the diesel (or Yanmar) junkies, how can I tell if my diesel Yanmar 2GM 20(F) is raw or fresh water cooled? I have the original manual and paperwork, but it only says, "If you have the raw water cooled version, do X," and "If you have the fresh water cooled version, do Y".
I'd like to know so I can read up on how to winterize one or the other.
