Fury 3 24p to bravo fs pitch 26 or 26.5? Are the Bravo cast as even or odd pitch with cup added to increase pitch? Thanks for answers.

I believe it is even
Half sizes are just same pitch with additional cupping I believe

Bravo are cast as even pitches. A 24P casting has cup added to make a 24.5, 25, and 25.5, then the 26 is a new casting, and so on. I had a 24P FS and now I own a 25P FS both are the same casting and the the boat comes on the plane just as fast with the 25P as the 24P but the rpm is about 200 rpm lower at WOT.Originally Posted by Phoenix 5

It's my understanding, and was said by Scott Reichow who was the head of Mercury Racing at the time, that yes, Bravo props are cast in even pitches, but cup is not added but actually ground out. So a 24" Bravo prop is actually cast as a 25.5" version, with progressively amounts of cup ground out all the way to the 24" version. They all are 24" pitch, but with different amounts of cup subtracted.
He also explained they take the cup out in varying degrees of the tip and trailing edges depending on what pitch # they want to hit. So, all in all essentially the same, but ground back not added.
Another thought, not sure if I'm really right on this point though, but makes sense to me, is that it would be much easier and more consistent to take cup out than add.
