My guess is 70 mph and a 24" Bravo 1.
I'm running 78-82 GPS with a stock 502, Bravo 1 with a 28P.With a stock Mercruiser 454 Mag and a stock Bravo 1 what can be expected for top end on average?
What's the best prop for this setup? My first inclination would be a Bravo One or a Hydromotive. Have no idea of pitch though.
somebody correct me if im wrong but i think the rule of thumb on a cat is it takes about 15-18 hp for a 1 mph.Thanks guys....
The wife wants an I/O Version because of the closed engine cover but I'm used to being able to run 90+ in my other boats.
What kind of HP do these need to run 100?

I dont think i explained it good enough. from what i read again i do not know if it is right but it starts of at a typical 65 or 75 mph cat since the faster you go it takes more hp to go faster.for example if the 22 daytona has a 400hp and goes 80 mph and you go to 800 hp`it should run 108 mph at 15hp per mph. i understand that there is much more to it like props, etc.i also imagine on a 150mph boat it would not be even close.somebody correct me if im wrong but i think the rule of thumb on a cat is it takes about 15-18 hp for a 1 mph.
I own a 1992 22 daytona and you are dead on the x demension.i measured mine and it is 5.5.i f you want to go fast with little power go with the 22 daytona with the blackhawk bottom.they ran around 105 with like 600hp.Yep, setup on this boat would need changing. With a quick check using a tape measure to the floor I came up with the propshaft 5" below the pad. I'm sure if I leveled the boat and drive angle I'd have a much more accurate number. Even if I was off by 2 inches it would still be way to deep for a >80 mph boat. So big money for short drives and nosecones would be needed to get it inline or above the pad to maximize efficiency.
On my previous 21 whacker center pod cat going from 3" below to 1.25" above the pad was only worth 3 mph. That was as simple as a jackplate and a Titus Nosecone for a total bill of $750.00. I can't imagine what a short drive costs.
Looks like there's going to be some discussin with the wifeabout going back to OB's so we both can be happy.
Thanks to everyone for your input.

Rare, expensive, hard to find parts...I don't think that is a good way to go...just my opinion...experiment between a 26 and 28 or find a blackhawk if you can..
Was that a hp500 engine or the standard 415hp 502 ?Had a 95 22 daytona with stock 502 efi added m-1 procharger 5psi emi exh 30p prop fastest ever got it was 90mph with no ecm mods rev limit was 5000 elavation where i live is 4000ft hope this helpsAlmost forgot stock bavo 1
