Drop your props off at a 1st class prop shop.. He’ll scan them to really see what they are..

Tell him this, and this only..

1) Engines are rated at 315 BHP @ 2925-2950 RPM

2) Tell him the accurate RPM you get now loaded as you use the boat, in gear. He may also ask for a vessel type, weight, and speeds.. Just be accurate in your response

Let him make the decision are to what to do..Personally I would not even suggest what to do. Remember, this is what they do and they should be making the calls.. You are their to provide accurate information, not express opinions. He could even come back and tell you your current props are trash–don’t know.
