2002 31 American Offshore with twin 300X Ooutboards
Currently run QIV hydromotives 15 1/2 x 26p @6500rpm approx 86 mph. Want to try a set of Bravo 1's but I believe they are 15 1/4 diameter. What pitch should I try?
Thanks jeff

26 or 28... depends on your rev limiter!

I think my max rpm would be 6800. My question is, will I be able to spin a 28 @6500 or above considering it is a smaller diameter prop.

I would think it will be close.

1/4 diameter might equal 100rpms.
Bravo 1's are about an 1" light on actual pitch while the hydro's are more true.
