1985 MR220V Prop Question

[jtaggart]

I have an 85 MR220V that I repowered with a 2018 Yamaha F115XB 2 years ago. It runs well but I don't think I'm getting everything I can and I am looking for information on changing the prop. Currently it is propped with a 3 blade aluminum 14 pitch prop. The boat runs 30-31 mph (GPS) at 5800 rpm. If I push to full throttle the engine will go to 6200 rpm+. Would

Seems your question was cut off after "would".

Well I guess I should finish my question. I am wondering if I go to a 15 pitch would that bring my WOT down below 6000?
