i e-mailed for a brochure and pricing....and if import fees apply..etc...waiting to hear back....but my biggest concern is where to get high grade fuel I think they use filtered light grade kerosene with an additive....and along with air cooling....they don't need "oil" changes...they must cost a kings randsom...

How many RPM's do they idle at? Run at?

.....a company rep also fitted a pair to his searay 39' which was an older boat.....and jackshafts and he said top speed is around 45mph...and about the same fuel efficiency as a pair of 6.2 liter engines...

....these turbines put out 400HP but 600 ft lbs of torque so they perform more like 600hp engines ....and weigh 158lbs....turbines are fascinating engines...

....they also have "lease programs" where they own the engines...and you pay then for hours of usage per year...he was surprised that they haven't been marketed in the usa...lot of road construction equiptment in eurpoe uses them....one of these 158lb engines is plenty for a conventional sized cement truck fully loaded....with a rear piston engine to "spin" the cement mix...

turbines will be the future of performance boating I think when they mass produce these....and they do spin the props really fast so you need a 40% bigger pitch than a comparable pitched big block with the same horse...and expect to see roostertail's baby!

Most turbo-shaft engines used in the marine environment have had their fuel controllers modified to use diesel fuel.
That little fella looks like an Allison used in the Bell 206 Jet Ranger- although good in the weight department, they lack the torque of the larger turbo-shafts that have been marinized i.e. the Lycoming LTS-101 (650 shp) and the T-53 thru T-55's that can be modified for up to 4000 shp (unlimited hydros are an example).
The LTS-101 is a comparable to a Merc 800SC in fuel burn, but has more available instantaneous torque. These were used in the Hueys circa Vietnam era. The T series Lycs are used in the twin-rotor Chinook.

If I had the bucks, I would much rather have a set of turbo-shafts than deal with the short life of a supercharged piston engine, which simply is a bunch of thrashing parts looking to beat their way out. Although turbines seem to be some kind of voodoo science, they are extremely simple to maintain. If you can change oil and plugs on a piston engine, you can do ALL the necessary maintenance on a turbine. If you boat 100 hours a year, the engines will still be running fine when you're taking a dirt nap.
