I suggest the same, your HP I think is 425. I would try the Hydro 24 or put that Bravo 26 on there. You should be getting 70-71 also with right prop.

1996 27 Fever
HP500 carb
26P Hydro Q-4 (tweaked by Hydro a couple of times)
73.6 mph (gps) @ 5100 - 5200rpm (didn't really concentrate on watching the tach too closely, too busy driving), speedo reading 76 - 77 mph
slight chop, mid 80's temperature, no current (on a lake)
3 adults, 3/4 tank of fuel

Best I've ever seen with this boat is speedo bouncing just over 78 mph (gps not turned on) in October afternoon (upper 60's temperature), light chop with me and a friend in the boat and low on fuel. Knowing that the speedo is 2 - 3 mph high with drive trimmed up where it was, would say running just over 75 mph - boat was starting to chinewalk more than I am comfortable with, though

Reggie report for my boat says he got 75.1 mph with the stock Mach 26P at 5200 rpm, 95 degrees (July test date) 6" chop, drive at 5.8, tabs at 3.2 . I have never seen that with the Mach prop, though.

We had the boat out this past Wednesday: 5 people, full tank of fuel, light chop, low 80's temperature and got 72.8 mph on gps. Probably could have gotten a little more out of it but the women ( my wife and my friends wife) don't like the "breeze" at that speed, sitting in the back seat. It took about 2 miles of running to get it tweaked to 72.8 mph (gps) and the women were getting unhappy

Thanks for the help will,
I was misleading, the 26 bravo is on there, came with it.
Yes 425pshp, wont the 24 hydro increase my rpms?
it is suppose to run 4800-5000, I'm at 5100 now.
Of course don't want to play the prop game, It took 6
on my last boat to get it right. Any one with my combo
with different prop? thanks

Out of curosity what, does Fountain test sheet say?? I just tried to look up what Fountain says for props on their web site?? I swear a couple of weeks ago they told you what props for certain power. But I cannot find it now????

I am pretty sure your boat came with the Bravo?? The Hydros are faster top end by 1-1.5 mph but slower out of the hole.

Has anyone tried to turn a 26P Hydro with 415 horse 502? I want to try it out but am weary of it being too much prop.

BTW - I called Steve H at Fountian and he is working on getting me the test report for my boat, that should help.

we tested a 1998 27 with a hp500 5100 at 70 with a 25hydro and a 1991 29 with 525sc 5300 at 84 with 29hydro all speeds were done on gps. we are finding out that you are not going to get much more than one or two mph with what ever prop you try unless you are out in left field . but the way you can get the boats to handle with different props is unbelivable .

I run a Bravo 1 30p rh at 5200 rpms at 83.1 on gps.96 27' Fever,502 mpi, stage II Procharger at 5 lbs boost.Throttle- Up propellors of Largo, Fl is currently doing a lab/blueprint on it and they say I should see a 2-4 mph gain! I have run left and right hand props and the rh handles much better and is just as fast,Before the Procharger I ran a Hyd. Qiv 24 rh at 70 on gps and tried several more Qiv's with the Procharger ranging from a 31lh to a 29rh,the 29rh ran about 83 on gps but blew out too easy after coming on plane.Hope this helps.
