I have a 15'3" foot flats hull made by angler boat mfg. the boat is relatively light and I have a 82' 75hp vein rude pushing it . I have no idea what pitch or diameter prop it has on it now but it's an aluminum 3 blade prop. Right now the boat will run 30-35 mph but over revving at that point I loose the prop at about 2/3rds throttle and then it just revs higher while really not gaining much more speed. The boat is a nice deep v in the front and shallows out to a shallow v in the stern pretty hydrodynamic looking. Any one have a similar boat and can give me an idea on to where to start with a prop For this motor? Looking for more speed

Your prop size should be near the base of the blades or under the prop nut.
The motor may be mounted too high. We will need accurate rpm and gps speed.
at wot(wide open throttle) if possible.
