Anyone know what I should be running with 500-540hp on 96OL SST
 

Had an engine built.. 500 to 540 hp in a 96 outlaw SST.

Bravo x drive. Sport tubes and open headers. does anyone know what speed I should be getting with this engine.. running Full MSD ignition. stock 96 454 thunderbolt fuel pump.

with a 26 4 blade was running 4500 to 4600 rpm.. max opperating range is 5200 rpms. was up around 70 mph.....

would a 25 3 blade mirage plus give me more speed and stability?

Three blades are going to be the fastest
on that boat.....the drive is fairly deep on
those.


I would think that you want to get your
rpm's over 5k too.

Can you give us more details. What length & weight is the boat? What did you have done to the engine? What is your propshaft depth? If it is stock outdrive setup it is probably deep 7 to 8 inches, then use a 25 Mirage.

I had a 489 w/ around 500hp in my 89 226 sport, 4000# boat. I was in the same rpm and speed range with a B1 26, after putting a 25 mirage on it I was runnig 74-75 around 5100rpm.

24 Outlaw? Sounds like you need to drop down to at least a 25 Bravo if you stick with 4 blades, maybe even a 24. If you go three blade probably a 25 Mirage plus. And trim that baby to the moon!

I have a 25p mirage plus on ebay now. It is in the swap shop now but had no contacts on it for 2 weeks so put on ebay. anyways here is the link. http://cgi.ebay.com/ebaymotors/ws/eB...%3AMESELX%3AIT

Didn't I sell you that prop, why cant you use it. Sorry it didn't work out

hey no prob. this stuff happens. Prop is great. Had so many questions on the ebay page that i had to say i owned it since new. people are a different breed on ebay. they want a damn birth certificate for a prop.

oops, I didn't even look at the ad. a prop, is a prop.
