How much HP do I have? 502
I bought a 1999 27' Fountain 502 Mag MPI w/ a cam & reprogrammed by AZ Speed. MSD 6 box.
The engine has been rebuilt before I bought it has 40hrs on it.
Bravo one stock setup with a 27P bravo 1 prop.
I turn 5100rpm. Speedo is not working.
How much HP doing you guys think I have?
Could I turn a 30P bravo 1 prop?

Our 1996 stepped hull 27 Fever with a HP500 turned a labbed 27P Hydromotive Q-IV prop up to 5200-ish, so I would say you are somewhere in the 470 - 500 hp range. You're probably around 74-76 mph with the boat trimmed right, too. You would lose ~ 300 - 400 rpm going 2" more prop, so probably wouldn't spin the 30P that well .

I like them. Mine are B&M Superchargers. I am only running 3-4lbs of boost right now. It is a very reliable setup. My limiter is raised so I can run mine to 5600 before the limiter will kick in. I usually cruise at 3500ish around 60-63mph gps with the 32p Bravo 1s. My 32s are not labbed yet, I plan on getting them done this winter so I should be able to spin them a few more next year. I like to run my engines at 5200. I do not feel I get much more out of them going past that.
