RE: TURBINE!!!!
If I remember correctly the jetcat or WREN turbines are around 10hp and weigh around 6 pounds, and a bargain price of $4000. This is just from memory though

RE: TURBINE!!!!
Jet-cat turbines vary in thrust from 3lbs to almost 40lbs. Spool up to 165 thousand rpms. You would need a two stage and a large gear reduction. To get it down to the 20 grand needed. Check out jetcat web site tons of info. Mostly helicopter info. But its my understanding there working on a gas boat gear box and turbine.

Jetcats come with gear reduction, I believe the output is from 19,000 to 35,000. in the pic the purple and gray housing is the gear case (water cooled).
