Got it Pat. Thanks for the help! Now I just need to find someone as nuts as me to buy it!:D

We are building a 588 Merlin block motor for the avanti. Going to run the stacks. Going for somehwere in the 650-700 HP range with out a high strung motor at all. Hopefully 80 is in our sights!:D

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.

I believe that the X dim on my straight V boat is set perfectly for 3 and 4 blade props. A -1" short drive would probably work with a 5 blade prop. Like I said in an earlier post, I'd love to try a box and shorty.
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.:cool-smiley-027:

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.

We might have an answer for you in 2 weeks :D:party-smiley-048:

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!

all this crap for 80?????? Jayhawk isnt welcome back to A Dock with less than 90 :rolleyes:

So instead of a hose down at Ketchum Cove I will have to wait an extra 100 yards? :rolleyes: :Whatever:
