Default Question on Hp vs Prop pitch
If I added 125hp per motor how much prop pitch do you think that would account for???

Probably the same prop. If you added more HP via NA and not blower then you probably need more RPM's to achieve that HP.

I added about 60hp to 454 mag and it added 400 rpms. I kept the same prop and went from 5000 to 5400rpms.

I went from 385HP to 425HP in a 24' boat and went from a 26P to a 28P bravo. Stayed around the same RPM, picked up 4 MPH.
