I think that big orange hand would have to on the 6 to be 60mph. 
1.50 gear ratio? That be 21% slip @56mph
The old set up must have been slip thru the roof to gain 16mph , wow.

Impressive pickup on cruise.
I would rather have the boat very usable in the range from cruise up to 95mph top end, rather than chasing the 100mph mark that may be done 2 or 3 times all season. I lost cruise going back down to the 30s, but I can get on plane. Cruise with the 32s was right on, but boat wouldn't get out of the water, took about a 1/4 mile. I need to track down someone with 32 5 blades to gauge the difference.
Keep up the good work, I do enjoy seeing your progress, data, explanations, and pictures.
These boats work well in the 65-85mph range. I haven't had it above 4800 rpm yet, and I like the results so far.

It was a little better than that with the 32s, and even better the faster we went. Slip was way down into the 7-8% range so it was the right prop, just couldn't get on plane with the drives/engines mounted so high. Also, all speeds taken with drives trimmed all the way down, and using tab. Once you lifted the tabs, thing took off like a rocket. Will use this year to get all the bugs ironed out, then bump the power a little next year. All in all, pretty happy with the setup.

What ratio are those #5's? 7 percent on a straight bottom old top gun is pretty hard to acheive

OK, call it 8+% then. They are 1.5 ratio, seemed to hook up better with the 32s, or at least more efficient when cruising (no grip at all getting on plane). Showing around 10% slip with the 30s right now.
Also, the 32s were labbed by Merc. I have no evidence to support this, but maybe they were pitched up to 33s?
I've only driven the boat for 2 hours, had it out twice. I will take better notes so that I can compare.
Joe, tried to call last week and left a message, I'll try you again.

Reason i ask, is because ive seen many ssm 4 and 5 drives claiming to be 1.5 ratio, and were not. They offered a ton of ratios for these drives .

You may be right, I've never had the drives open to count teeth.
Possible they are 1.55 but not sure that then show worse slippage. They would have to be lower ratio to show faster mph, therefore giving a false reading of a lower slip (if you assumed they were 1.5 and were in fact say 1.35), correct?
