Who lab finished your 24 Bravo's.
The best way to determine what prop to go with is to try a stock set of props. You never know what has been done to the props you have now. If your props are a "standard" lab finish then stock 24 Bravo 1's would run about 4900, which is a good rpm for your motors.

Julie, Talked to Dean from SA yesterday, said the prop you repaired did fantastic. He was also amazed at how low the price you charged him to repair was. Keep up the good work.

tony,i just got a one inch drive spacer i'm going to try,prop slip is around 15%,something you didn't mention? ahhh speed,mine up over 80 mph the boat feels like the prop is the only thing in the water.right now i'm running a 28 pitch labbed by merc also @ 5800 rpm's,when i put my 27 pitch labbed by dah the boat run's alot faster and quicker to speed but i'm turning 6000 rpm's,i have a 29 p hydro 4-blade coming to try next.there alot of prop's out there and there all different.someone has a 30 p,but he won't sell it i won't mention his name.

Re: prop suggestions ?
well i put the 1" drive spacer in and the only thing it changed is that it's very hard to get on plane with either the 4-blade or 3-blade,speeds the same.bottom cavitation plate still above the drain plug hole,point of nose cone about five inches below the hull.
any thoughts??????
