I would have never guessed this would be possible in a SVL with... 5450 maximum rpm, 31" x 15 5/8" pitch and diameter props, 4750 lbs, sealed Mercury 525 with factory certified seals, 1.50:1 drive ratio, 1.7 ratio rackers, 8.7:1 compression ratio whistle test, stock ECU, water has to come through the outdrive and the drive has to be a minimum of 1/2" below the bottom of the running surface. Plus they have to pass the pre-event and post event inspection to confirm passage of all of the class rules.
