AS per Mercury, if you are wanting to replace a 21P prop with a Bravo 1 FS, you need to increase pitch 2". Anyone here do this on a 150 merc 4S? If so , how did the 23p compare to the 21p? did it effect your RPMs? did it give better or worse performance?
I Have been thinking about a Bravo 1 FS 23P, but no sure if it would work and as you know they are expensive.

The advice Mercury was giving when I bought my Bravo 1 FS was to go one pitch higher than a properly pitched Tempest Plus. My 22p Tempest and 23p Bravo 1 FS hit almost the exact same WOT rpm 5800 ish on my Merc 150 fourstroke.
The Tempest was a dog of a prop for me, though. I sold it even after Croxton worked it for me. It would blow out at break over badly.
I run a 21p Enertia Eco which has a 16" diameter and is made of the X7 allow. It is the best prop in almost every category of the many I tried. My Bravo 1 FS is my backup.

Go up 1 pitch when switching to a Bravo XS. The Bravo's are a terrific prop in every area. They like to run higher than a Tempest at WOT.
