What are your current wide open rpms w/ 2 people on board and full of fuel
(or what condition do you know the wide open rpms).
What is the current 20 pitch 4 blade prop. Is it SS, aluminum, plastic.
What brand/model.

Usually a 4 blade is the best all around prop. Especially if your turning
the right amount of rpms. I doubt you are though.

My guess is a good 18 4 blade SS would be about right for this boat not
knowing the info above.

From the engine manufacturer... AND/OR, if you give us all information
about your boat & engine, there are people in the NG who can pull their
attention away from politics & back to boating long enough to impart
some good advice, even some expert knowledge...!

Thanks.

found out that the engine is rated for 4200-4600 rpm at WOT. It left the
factory with a 14.5x19 prop (3 blade) it currently has a 20pitch 4 blade.
it
tops out at like 35; but the data I've found said the boat should reach
45-50.
