Shorty??????
I have two test report brochures from 1996, so it was the non-step hull.
Test one was with a 502 MPI with a blackhawk drive. 76 MPH, 27P props@4900.
Test two, 502 MPI, bravo drive, 79 MPH, 27P Mirage@4850 rpms.
I'm not sure if these two tests where with the exact same hull and motor. It looks like a bravo might be faster. But, who knows how much time was spent dialing in either setup.

Dave,
What do you think about a -1 shorty on your boat? I do remember that the prop shaft is about 1" farther below on your boat with the semi pad.
By the way, my boat ran 76 with a stock 27p M+@4850 and 77+ with a Throttle Up labbed 27p M+@5000. We shall see how she runs with the 27p M+ BBlade is labbing for me.

Hey question for you all.
Anyone know of a 24' step bottom Super cracking 80?
Superbash and Dave M. have both run real close.
We heard of lots of older 24s with big power turning big numbers.

JayHawk,
I am currently running around just under 500hp with an out of the box 26 bravo. Haven't done much prop testing other than switching from the 25-3blade that came with the boat. I would think you would want to start with a 26 and go from there. What rpm's are you looking to turn. With my 454 it is reving pretty high which is why I running the 26 instead of the 28.

If you are looking for a 26 B1 I have one for sale.

Hi guys,
I had been having an idle surging problem so I replaced the IAC and ECT of the fuel injection today.
Fueled her up and snuck out for a test ride. I ran solo down to Old Saybrook to meet up with a bud.
My gps read 77.2mph @ 4950rpm running south with a tail wind. Running north with 2 on board 74.8mph @ 4850rpm.
I think I've got an outside shot at 80 running solo, spinning a labbed 3 blade, and running on fumes.

Had a 96 that would hit over 80mph.
Man I sure miss that boat. The wife hatted it and if I had been able to keep from pulling that throttle back it might still be in the garage.
I will say that when you got over 70mph you had to "drive" the boat and give it all of your attention.
I will always be a fan of the 24 Superboat!
