Craig,
There were two auxiliary propulsion units (APUs) mounted about 1/3 of the
ship's length from the bow. They were electric and could be retracted when not
in use, and rotated 360 degrees. A skilled ship driver could use those and the
main engine to maneuver pier-side or get underway with

The gas turbines on my old ship drove the main reduction gear by pushing the
hot exhaust gas over a turbine, which was mechanically connected to drive an
input shaft. This was called a fluid coupling. The red. gear brought the speed
down from some high RPM to about 100 RPM, and then the propell

90% of such a proposal would be a materials problem. Advantages
are that we're only talking about maybe 20HP, so the diameter of

out; the development bill would be large.
Hey, y'all remember Parnelli Jones's turbine car at the Indy 500,
right? Mid-late 60s? I think he ran it 2 years and it was cleaning up
the first time until a transmission bearing broke. I forget what
happened the next year, maybe a crash? Then the race organizers banned

Problem set you need to consider:
1. Turbine engines do not "idle".. what you would equate to "idle" would be
70% RPM. Below that, the burner flame front and balance of air flow through
the engine becomes unstable. Operational power for small turbines comes on
in the 100,000 RPM range which transl

Any idea where to buy one?
