I recently purchased a 1991 NT 26. The boat has the Yanmar 4JH2-DTE engine with the Kansaki Tuff Torque KBW21 transmission. I have been told that the motor oil, engine coolant, and transmission fluid recommended by the manuals are no longer manufactured. What fluids are being used in their place? Any suggestions appreciated. Michael Garrett 1991 Nordic Tugs 26 "Green Eyes"
