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.
