What is the RPM's while trying to plane?
Max RPM for that engine is around 4600.
A 13pitch prop is way wrong, as I said my 95 2400 came with a 14.5X17p, and I have no problem getting to plane. It's not a hot rod speed wise, I think I have seen 35 to 38 mph at WOT.
I can hold plane ay 22mph (GPS) with out a problem with 6 adults on board.
