Stingrayaxe, thanks for your feedback.
From my post #10: May be a couple wks before I have an opportunity to run the boat to provide the RPM data.
Remain surprised that apparently mfr's don't provide prop recommendations for boats they manufacture.
ie:
For the 1994 180BR I/O 5.0L (190HP) Alpha One 1.65:1 ratio with standard 14X19 prop and 4,600RPM max, the recommended prop to maximize ski/holeshot performance is _________.
Would seem a mfr could evaluate this when testing their new boats, and include optional prop sizes in the owners manual.
Instead, apparently owners have to experiment and use RPM/pitch change relationships/etc. to guess which prop to try.
Doesn't make sense to me, but maybe I'm missing something.
