Im not running a Bravo so this may not be the info you need,, but if its any help Im running a 350 260 hp mercruiser with an Alpha drive with a 1.62 ratio on my 23 Tsunami, and found the best prop for my use to be a 15.5" x 17 pitch Mirage. It performs well across all rpms and speed ranges
I tried a few and this seems to be pretty close to perfect for me anyway
