Hey Liquid,
Just curious about what the absolute lowest slip could be with a v hull running an I/O. The reason I ask is that I have used some of those calculators such as Winprop. In order to get my rpm, GPS Speed, and slip to match up I have to lower the slip down to about 7%.

My 23' Concord LS-7 ran 68.5 with a 454 mag (365) and a 23" quicksilver 3 blade @ 5200. When I went to a 2" shortened lower, I saw 72.5mph with a 24" hydromotive (when I could get it on plane). A 24" Bravo1 was just a tick slower, better to plane, but wasn't as stable. Both props also turned 5200rpms. This boat required full trim to run fast and it was very prone to chine walk. You had to pay very, very close attention and be in tune with the hull or you'd lose control. The best hole shot prop with the shortened unit was a 21" mach stern driver 4 blade. The boat was a rocket out of the hole. It also topped out at 60mph at 5600rpm (valve float). Do the slip calcs on that one!
It sounds like your speeds are good numbers.

Does anyone know what site Winprop was moved to?
