[C320-list] Dropping water temperature

[bruceheyman at cox.net]

John,
I think that is true as it improves the efficency of the engine and the burn is more complete.  However raw water cooled deisels engines run cooler with thermostats that typically start to open at 145 and are fully open by 165.
I crew on the tall ship Pilgrim and we have a 1945 300 horse (three cylinder) two cycle deisel that brings a whole new meaning to vibration.  We've never been able to get the engine over 130 deg.

 I have always been told that diesel are made to run on the hot side.? You will cause more damage running it cold than running it a little hot.?? John

But why did you shut it down for under temp? Every time you start it 
the temp is under for several minutes.?
