which prop bravo 1 ???

I have a SR 21ft advantage. previous motor was a 425hp 454 with a 23p mirage and a 22p bravo 1 prop. Will be replacing motor with a 625hp 540 ci motor and need some suggesions for prop sizes. the 23 topped at 70mph and the 22p topped at 62mph. looking for mid 80's to low 90"s.

Try this as a starting point, put in your old numbers and them start changing to new power and prop pitches
