express 265 prop question

Good morning,
I have a 2004 Grady White 265 express that I repowered with 2022 Yamaha F200s - the dealer installed 14.5 x 15 props. But I think I’m under propped. Running @ 23kts at 4000 rpm. If anyone has performance numbers for same engines with a higher pitch it would be appreciated

Thanks

14.5 x 15 seems awefully small for 3 blade. Are they 4 blade?

Are you testing with trim tabs up all the way and not doing anything? Best to nullify the trim tabs from the equation. Do testing without tabs.
IMO, using tabs on a 265 is just asking for problems. Put them up, pull the fuse and use your motor trim.

Do your testing with at least a full 130 gallons in the main tank.

I have zuke 200s that are geared differently than Yammies so I can't recommend the same as mine. I have 4x15.25x22.

As a starting point, I would have guessed at least 15.25 x 15 or 15.25 x 17,three blade, for F200 i4s
