Need info for prop size
 

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:boat:

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.

I run a left hand 30 pitch bravo 1 on my 2002 29 but with a blower, not na. Little over 700hp but big torque.
A buddy of mine had a 1998 or 99 29 fever and ran a 27 hydromotive left hand clever style 6,000 rpm's (blower) around 90mph.
I read that Fountain changed the bottom or x dimension around 2000+ and the bravo 1 is the best prop for those newer hulls but the older bottoms like the clever style.
With the 2" shorty it is a crap shoot and testing is the best way.
Mine came from the factory with a 30 bravo 1.
Keep us updated on your testing. I was wondering how that setup would run.
I'm thinking about a nose cone since being above 85mph I heard they help slip alot.

Today im pulling the Stock bravo 30 prop off my baja and trying it out on the fountain. I will keep you posted.

At wot Running a stock 30 bravo maxed my rpms at 5400.

Does anyone know what a 31 Herring 6 blade prop would do on this combo? Currently im using my tabs to get on plane, Probably because of 2' shortie. Would a 6 blade add to much stern lift? How would the bout ride with a 6 blade? Thanks

any updates to this thread?
