That's sounds about right - my prop calculations say a 27 is perfect, so a labbed 28 is the way to go. I think your engine is the problem on the lower 100 RPM. What where the waves like when you tested?

Ok got to test yesterday. Two differant sets of props. 26 four blade bravo ones. The boat it harder to get on plan ( but I expected that). 3500 rmp I was doing 47 48mph. WOT was 5800 rpm doin 79.3mph on the gps. Then I switched to a set of 28 four blade bravo ones. Boat was harder to get on plane. 3500rpm was doing 50 51mph. WOT was 5300 rpm on one prop and 5200 rpm on the othe prop. I think this set of props need some work. Boat was doing 80.2mph. I think there is alot more to be had with the right set of props. Still trying I'll keep you updated!!!!

Well run some 28 bravo that have been changed to 27. I could turn them 5400 rpm boat was doing 80.4 mph. 3500 rpm was 49.2mph

Well I've think I've come to the conclusion. That for the money the shorties cost and the little gains I've seen. It better to stay with your standard lenght drive. I think I'm going to take the shorties off the Cafe and sell them. Anyone interested????

i went through the same thing i put the shorties on then put it back to standard hieght one inch at a time but still harder to get on plane because of the sport master lower.
