Shorties on a cafe?
#66
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!!!!

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?
