Ditto on the pink vs. green antifreeze. The pink stuff is non-toxic and can even be used for winterizing your potable water systems. Just in case you used the green antifreeze for the potable system - I would flush it out about 20 times and bleach it and scrub all the nooks and crannies before drinking water out of them.
With regards to the white smoke, this is not usually unburnt diesel but post-combustion water vapor. Diesel burns black, oil burns blue. Water burns white. White smoke from the exhaust during warmup is normal. If it continues it could mean water contamination of your fuel or water entering your cylinders somehow. If it was a head gasket issue the exhaust should be blue in color - not white. (others - please correct me if I'm wrong).
With regards to your engine RPM's and raw diesel - at higher RPM's a diesel engine can easily not burn all of the fuel injected into the cylinders. Once again, this is not out of the norm. Our boat regularly ejects small amounts of unburnt diesel at start (cold engine) or during/after docking procedures where we have several high RPM run-ups to add steerageway or slow the boat down. If it's constantly ejecting unburnt diesel that is a whole different problem.
I also noticed that you have single clamps on your mixing elbow for both the raw water intake and the gas/exhaust intake. With the vibrations they go through I would highly recommend double clamping them.
