Best prop for a 75 hp Johnson on an 18' bass buggie pontoon boat. Would like to know size pitch and 3 or 4 blade. Thanks in advance

Won't get a proper answer for that. Test current prop as usually loaded, on flat calm, no wind water cond, once knowing max wot rpm achieved can go for a prop maximization, not before that...

Happy Boating

The year of engine or model # can help. You might have a V4 or one of the various 3 cylinder engines.

Long or short shaft? Have you run this combo yet? if so, what prop is currently on it and what was the WOT rpm?
