Just recently purchased a 1997 29 fountain with 454 mags in it and was wondering what props would work best on the boat for top speed ?

Dit it come with the performence sheet from Fountain? If not, you can call the factory wiht your hull ID numbers and they will fax it too you. Has all the trim settings, rpm, speed, weight info from the test drive with the props.

Yes it did come with the spec sheet it has 14.5 by 26 4 blade Mach props on it but almost all the other fountains I have seen have hydros on them and was just wondering if they would be a better selection.

Any semi-cleaver propeller typically produces great results.

I would typically recommend Hydromotive for stock props and Throttle Up for CNC Props.

Post your performance data and we can take a look.

The spec sheet says 79 mph at 4950 rpm tabs at 3.0 and drives at 5.3 . 60 mph at 3650 rpm

where are you located, i have some 24 HYDRO Quad IV's in 24" collecting dust. They seem to work good for fountains. I am in MI and if you are close I would let you give them a try. Just might have to wait a month or 3.

chkmt251,

What is your gear ratio?
What props were run at the 4950 RPM at 79 MPH?

I want to look at the propellers efficiency before recommending a propeller to you.

It has 1.5 bravos and the props used were the mach 4 blades 14.5 x 26

I would have to say a 25 hydromotive or a 24 merc 4 blade is just what the docter will say for that application. Get rid of the Machs those are Junk! My preference would be a 25 Hydro maybe even a 26. But I think with 385hp and 1.5 bravos the 25 hydro or the merc 26 is the prop. Anyone else agree?

What speed difference do you think the hydros will make over the machs? Thanks to everyone for helping me out with this .I owned a 25 ft checkmate before so this fountain thing is all new to me.
