Russ has the world's record for a prop driven boat at 221mph...Unlimited hydroplane..Lycoming Turbine 3000 hp and a 7,000 pound boat....
Most hydros are now in that 200mph range top speed and do laps averaging 170-180 mph or so...last year on the Detroit river a gas engine won...amazing?
Mitch Evans (U-3) also won 2 other Unlimited hydro races last year with his 12 cylinder Allison Piston Powered U-3. The Budweiser team helped with the U-3 updates which had undergone extensive changes from previous years.
If you want to get into the finite discussion on the bottom -prop-sponson configurations with the hydros, I suggest you chat with the Bud people (U-1)UH World champions again and the Coopers (U-3)..
