Thank u guys for the input! We're gonna run it again full out and see what we come up with!!

My friends TG with 725 Zuls runs 29" Hydromotives but with 1.36 ratio. You might run out of prop with a 1.5 not to mention difficult to plane with the big wheels. His setup runs 99-100 in fresh water.

My '03 with 525's has labbed 32's, ITS with sport masters, runs 84-85mph. We have the same boat at shop that has a set of 30's on it. Also have a 575 boat there it has 32's on it.

Are 30 pitch bravo 1s common on 575s with a twin step? These motors are re built by Ron potter and have the Arizona speed shop pulleys, and also have ported and polished heads- there dynoed at 700 hp, we ran the boat up to 84 and had trim and power left, also tabs were at 3, don't remember the RPMs , my question is- do 30s sound right for this set up- or would 32s seem more logical?? Thanks for your input!
