And I guess that "sporty drive" must be slowing you down too? How is it the 25OL has "only" 85 HP more than you claim yet is running 12 MPH faster than you? My 502 is in the 450+ HP range and will run right at 70 in perfect conditions. 66 MPH, GPS, ANYTIME.

Have you been in other 272's Zeke? I'd say you're the one with questionable numbers. If you have/had 450 HP and can't get that tub over 63 MPH somethings wrong with your setup.

Hp vs speed:
1100 hp-my 272 runs 100 mph with 32 labbed at 6000 rpm's with 1.50 gear
1050 hp pulley-runs 96 mph touching rev limiter at 6200 with 30 pitch labbed and tweaked by Cutting edge
old motor-ran:
950 hp-ran 92 mph empty/89 mph with full tank of gas and 4 passengers
with blower belt off (I dynoed it to run either way)
74-76 mph with 650 hp under absolutely perfect conditions 26 labbed at 5400, very finicky though to load and temp changes, will slow down to 70-72 on real hot day running with heavy load
With un-dynoed 502 with 8 psi of boost ran 75-78 or so, with first 540 that only made 690 blown hp on the dyno it ran 78-79 mph or so years ago but later ran 84-85 with more timing and boost (not dynoed at that point though)
My posted hp numbers were all actual dyno numbers BUT with the more generous j607 correction factor and no acccesories so you could probably take 50-75 hp off those numbers if you were comparing to merc racings modern sae rating on there blue motors.

One other factor, is most my speeds have been in freshwater at 700-1100 feet above sea level so I am sure you salt water/sea level guys might be a titch fatser with equal hp.

Comparing my #'s to articfriends, with my 400ft higher elevation i would say my #'s are pretty accurate and comparable to his. And my dreamo meter always showed 5-6 mph faster than my gps.
Last CE 26 i ran i was 73.9 at 5900 which is too high rpm i need to be at 5500.
But with that prop full of fuel, 2 big coolers 6 adults i can still pull 71 on gps at 5800.
My prop will be sent back to CE to get my rpm back down over winter

smitty well said!!!! and zeke nice speed . it is nice to hear guys like you tell how to get speed out of your boat. i hat when some guy tell you to put somthing on your boat that will make it faster and it goes slower. funny think is when guy tell everybody he goes 90mph and you run him and beat him and i only go 82 gps winter comes then we find more ways to make more ponys to go fast
