I just purchased a 1998 29' Fountain with a single 540 700 H.P. motor, It also has a Imco Extreme Advantage OutDrive with 2' shortie. What prop would best fit this combo? Any Info will be greatly appreciated Thanks- Patrick

Have you run the boat? What prop is on it, now?

I have not ran the boat yet, It came with a 26 Bravo 4 blade. That was with old hp-500 motor set up.

My 97 had a 565ci. that dyno'd 725hp I used a hydromotive 28 and spun it 5800

Is the motor supercharged or NA? I would think you would want to keep the rpms higher for an NA motor

The motor is n/a, At what rpm should it spin at?

5500 - 5600, I would try a bravo 1 30P

I currently run a Bravo 30 on my 27 Baja Boss 509 m3 Procharged. I thought a 30 would be to big for the Fountain only puting out 700 HP.

only 1 way to find out... try it, the Fountain will have a much more efficient bottom vs 27 Baja

call Brett a BBLADES and try a few different props from their loaner program.
