[50boat]

Hi, like some input about prop Dia. Pitch, cup # 1993- 33 open 350 hp gas ,, loaded light fuel full, I think I have way to much bow rise and full down tabs most of the time. Maybe 50percent down at 4400 rpm, thinking x number of prop cup will give some stern lift and reduce down tab drag. # 2 does any one know the the thread pitch on the prop shaft and the shaft Dia. Thinking of changing props to larger Dia. And 3 blade to 4 blade no shire close to the hull the prop blades can be thanks to all
