Hey Zup, you are being way too modest. You've got the Zuperboat dialed in and she's probably the best running Superboat in existence today. It only took you about 8 years...:lolhit:

Superbabi vs. MDG is not only Bravo vs. Konrad but older hull vs. newer hull... :drink:

Mike, yes 5500 rpm's. on the Ron Potter Motor. Pat, I would guess an 800 on the newer bottom would be in 95-96 range with the XR.

Gary spinning a 32p at 5500 with a 1.5 gear and 94mph gives you a slip of 15% Spinning a 30p at 5500 gives you a slip of 10%

Mike, we played with a merc. maxiums 5 blade 32 cut down, more like a 31. That hull likes the odd sized props, with the 600 sci it was a maximus 5 blade
28 cut to a 27. So I guess the slip is at 13%.

My set up spins a 29 p5x hydromotive lab finish,94 at 6000rpm,i have also run a bravo 1 31 labbed 92 at around 5700-5800,one thing that i have noticed is that boat picks up rpm and speed with a lot of trim,doesn't seam to lift the bow much more but seems to losen up prop,most step hull v bottoms reach top speed at very little positive trim,was thinking if drive was a little higher might losen up prop a little.Was also thinking a 5blade herring might be nice prop on this set-up.Also another big factor is weight,mine has the race lay-up not sure if any lighter,not sure on garys hull,zuperboat hull i heard was built super light and has always run real fast

Slip with the 29 is 14 % and the 31 is 17% . Good slip numbers mite not be the fastest top end. Go figure.

And from the other post:

Hey Zup,
How's my slow boat doing?
68mph at 4600rpm with a 26p...:lolhit:

Well, my last run in Oct was 84 mph. 775 hp, 29 L hydro, 5600 rpm. 3 guys, less than 1/2 fuel

Last year we hit 90, same prop @ 5900 rpm, no fuel and 2 guys

Same water conditions

Pat Velocity hulls usually have good slip numbers. Its the pad. You numbers for 4600/26p/1.5gear/68mph give you a slip of 9.9% . Great number. PE ,s 5600/29p/1.5/84mph = 18% 5900/29p/1.5/90mph=16% Gary,s boat going from 15% to 10% at the same rpm with less pitch could be from different prop designs/ diameters and number of blades. My boat with a 5 blade had great slip great grip but slower top end. Like Pat said earlier Ive been messing with my boat for 8 years. Ive give all the credit to Skip over at MRD. I should have just dropped off the boat their 7 years ago and I could have saved alot of time.

Mike, remember Rick Blueprinted the Superbabi bottom, how do you think slip numbers play into that ???
