COOL! literally! Those chillers sound quite interesting. I'm suprised that they had only 30 HP motors to be 150 ton. In fact, if those things had a 10 EER (which I hardly imagine they were that efficient), they would be about 200 HP (150 ton equal to about 150 Kilowatts. 150KW / .746KW per horsepower). When I worked up at Reynolds metals, their chiller had a 400 HP compressor motor on it. The motor was about the size of an oil drum laying on it's side. Those weren't radial though, but centrifugal. The centrifugal compressors were a unique and modern design and that was the first building to use them at the time. The only drawback to them is that they produced the most god awful scream. Standing next to one was like standing on the runway beside a 747 at full throttle.
You speak of the air conditioners producing a fog of cold air, my G.E. "Fashionette" portacool in my workshop will do that! It is uses the spine fin coils, and uses R12 to produce a chilly 38 degree output temperature. When I open the door to the workshop, it lets in a bunch of humid air that instantly condenses in the chilly output of the AC unit...gotta love those old spine-fin coils!
I believe Chrysler's outboard division was sold to Brunswick marine (IE Mercury) back in the early 80's, and was re-named "Force" I've noticed that those outboards end up on the back of some of the lower end boats out there as package deals. Although the exterior paint scheme has changed, the engines are by and large the same ones they were back in the 60's. The problem is that they are being upstaged by many of the high-tech 4 cycle and HPDI designs offered by other manufacturers.
