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.
