I have just
got a '89 Canadian Edition Vista (V hull) with a Nissan 90 HP. I am
running with a stock 18" Nissan prop. The anti-cav plate is
about level with the pad and I have a power trim. I am getting WOT
of 5500RPM and a speedometer reading of 45 MPH, I also have tried a stock
20" but the RPM will only get to 5000 so the end result is about the
same. Is this about the best I can expect? Although I've been
around boats for a while I'm new to performance tuning so any suggestions
for improvement would be welcomed.
