1996 27sr1
 

I have a 27 sr1 I am putting about 625 hp in it I have a bravo with 1:50 gear ratio what pitch prop do you'll think would be best I was figuring a 26p bravo what is you'll a opinion

Many moons ago I had a 2000/271 Fastech with about the same HP and gear ratio and that's the prop I ran.

Thanks

What mph do you think my boat will run with it having no steps

Hi

I am far from shure what kind of speed you will get...
I have a friend at Lake Norman with the same boat as you 496 special version 600 + hp Arround 72 mph...
I have a 271 Sr1 with a 496 HO Bravo XR 62 mph GPS so far with a Mirage plus 23 :-)

And then you have this article :

Please let us know your results ;-)

at what Wide open throttle rpm range is that motor?

5400 to 5600 rpm

I have a friend that has that setup. Running 26p Revolution getting 71mph.

The last post in this thread were my results... And noticing your location, on the same stretch of water you'll be using.

I think under perfect conditions and with the correct prop, and 625 hp 74/75 mph should be possible.
You have 200 hp more then me, my 62 mph was with 2 persons and 3/4 fuel tank and kind of flat water.
I am sure I will reach 63 mph under perfect conditions ....
