ProCharged 502 Checkmate Prop
Hey guys,
I have a '94 253 Convincor with an M-3 procharger on it pushing around 700hp. Right now I'm running a 30p Bravo I 4 blade. I'm getting ready to drop the power down to about 650 so I can keep my outdrive under warranty. How much does anyone think the 50 less HP will affect my performance and am I gonna need a new prop?
Thanks

Yep it'll kill it ... eventually. But, I've been running 696 hp (557 NA) with a bravo drive for 4 seasons. 500 hp (ZZ502) 5 seasons before that. Both propped for +,- 5600 RPMs. Trick is (as far as I'm concerned) is no hole shots, careful re-entry during/after air, and OD fluid change every 25-30 or so hours. In a nut shell, don't beat the he!! out of it, and good maintenance. Beat on it to much, and it's bound to break.

Unfortunately I've already found this out. I bought it last season with a stock Bravo I, never beat on it hard but it was already on it's way out. I just got it back from being rebuilt by All American Drive Services in MI and it's rated for 800hp now. The whole reason I'm lowering power is because they warranty the outdrive for 2 years if it's at or below 650hp.

They completely rebuilt it from the inside out. Thicker bearings, thicker/stronger shafts with 25% twist rates, stainless steel tower, stronger u-joint, treat and polish everything, etc...
Go on their website, they do some pretty cool stuff. Spend way less than I would on a BMax for sure. George is the owner and is one of the best guys I've ever dealt with.

To your original question, I would say you will end up with a 28 Bravo.

Not trying to come off like a jerk as I know George does good work. But, how does the warranty work? I mean, they rate the drive for 800hp and warranty it up to 650hp. Many people only have "guesstimates" to the actual power they are making.

How much speed do you think I'd loose with a 28P?
