Sounds like a great plan to me. Those 6 blade barracuda props Throttle Up is making look wild...:evilb:
On my little straight V 24' Super the prop shaft is 5" below.
She runs fastest with 3 blade props but can be a real handful to drive. With a 4 blade she is a tick or two slower but handles far better. I have tried a 5 blade and the boat runs real smooth and I'm sure would handle the rough even better than with a 4. The problem with the 5 blade on my boat is that I have to trim to the moon to get her to run fast.
I guess to go along with a 5 blade I'd need a short lower.
Would you agree?
I don't mind spending the extra $$ for a 5 blade but a short lower is not in the budget yet.

zuperboat,what size bravo prop were you running with bravo set up? I heard that boat ran close to 100 when first run,don't know how much power though.I know the konrad will be slower than the bravo,but that is why i am installing big tube headers so my engine will make a true 800hp.If i were running a bravo set up i would have not spent the extra money on the big tubes(50 hp extra on this engine)because the bravo would be short lived with 750.I feel that this boat should run about the same as a750 hp bravo set up,but with complete outdrive reliability,and low maintenance.won't be long ,she will be in water soon.

When I first met up with Zuperboat his boat was power by a 575+Hp/540cube engine hooked to an Imco Bravo drive on a 12" extension box. The boat was vary fast, 85+mph, and if I remember correctly, 26p Bravo 1, 1.36 drive ratio. The drive broke 2 or 3 times, then the speedy #4. I'll let Mike tell the rest, it is his boat after all...:D

Hey pat i think his boat originally was sold to a guy in california,i saw it in hot boat in reader rides(i think) I thought it had a blower motor 750hp or so and ran 100.Thats what john at superboat told me .I don't think he ever ran it himself so i guess a lot of second hand info.Anyone ever ride in it with the 750/ bravo setup?

From what Zuperboat told me the boat was originally rigged at MRD with a 750HP blower motor, Imco box, Bravo drive. And yes, she ran close to 100mph. Mike brought the boat back to LI from Texas without power. Interestingly enough, my dad lives on lake Conroe where the boat was.

I 'm sure with my 801hp I would be at 100 on salt water with a little prop tuning to keep her right at 6000rpm. (94 on fresh water in havasu stock Bravo1 prop)

That is flying!:eek:
How that drive holding up?
You either got a real good one or you baby it.
From what I've heard DonY2K did blow his drive chasing triple digits. I think FX wrote that JC was going to detune his motor a little.

Awesome! I think you need to coordinate a Havasu Superboat fest! When's the ideal time to head there? I want to make it there this season or next, possibly do one of the major runs, but also play a little - what can you recommend? Maybe this needs to be a new thread topic.....who's in? :drink:
