Not recognised by the UIM but Callan Marine ran 203 at the 03 'Lake of the Ozarks Lake Rescue Shootout' in a Tencara 43 (formerly 'Jolly Motors') powered by twin T55 turbines.
I was there and saw both of their runs that day. The first pass was 205 but it wasn't allowed. The race officials said Callan "jumped the start". The sound of that boat at the finish line was heart-pounding. There is NOTHING on the water to equal 5000 screaming horses from turbine engines!! When the speeds were posted the spectator fleet went wild!!
Their run this year almost ended in disaster. Lake Of The Ozarks in the state of Missouri is a very narrow, shallow lake with rollers coming off the shoreline down the course. At about 180MPH, throttleman John Cosker trimmed out too much and the bows rose. Then a roller caught them on the port side and the cat started "hopping". Before they could settle the Tencara down, the rudder and its fiberglass housing was ripped off the transom, ending their run for the record.
Dave and John are building a new cat from their own design. With 3000HP turbines and BPM shaft drives, they are expecting 220+. John told me the turbines weigh only 550lbs. each.
The Tencara is now a test bed for the Sterling Torque V12 motors. They are making 1350HP each naturally aspirated. Sterling will also experiment with supercharging and twin turbo setups making from 1500-2000HP.
