I followed your link but it is not for the 4JH2E version. It is differnet at exactly the points I am interested in. The cooling system and heat exchanger. Do you have a link for this specific Yanmarengine?
Is there anybody out there that has a PDF copy of the manual for Yanmar 4JH2E inboard engine.
Thanks a million,
