Also if I recall they used Diesel coupled to jet drives to get on plane then the turbine / arneson was kicked in and pushed the whole deal by itself.
Again just my recollection...
Found the info...
http://www.gentryeagle.com/engine.html
"Total, (2) MTU 16V396TB94 diesels each generating 3480 H.P. are coupled to KaMeWa #63 waterjets. The gear boxes are AFBU7755's. In addition there is a diesel fuel burning Lycoming Marine Turbine #TF40 developing 4500 H.P. coupled to an ARNESON surface drive turning a Rolla REXP 5 bladed cleaver. In addition there is a lube oil transfer system, engine alarm system, and fuel management system. Fuel consumption is approximately 328 gals per hour at 45 knots under the MTU's only, giving a range of approximately 1250 nautical miles."

There has to be a reason for the jet drive.maybe it the gear boxs or converting the rpm down??
