If your running a true 28P stock Bravo @ 5500-5600 rpm, a New Bravo FS 30P pro finish as they come from factory, should turn 5400-5500 and get you 79-80mph with nearly same acceleration and with less trim input.
If you want 5600-5700 rpm with as much if not more acceleration get a 29P, Teaque Marine has them on sale.
High slip is not good, but your out drive will last longer, if you can get on plane good and boat handles good, all will last longer.
I gained 4-5 mph going from a 30P stock to a 31P & 32P Bravo FS, these props have more blade rake, exhaust hub cut down, which should help prevent lifting rear of the boat at high speed and these props get on plane very well and a medium finish, so they hold up to the horse power without throwing a blade as some thin bladed lab props sometimes do through hard use.
Just my 2 cents and what's worked for me !
Running 96mph with stock Bravo One gear case on 2 GPS units, now ready for SC Imco lower ,Bravo One lower is at its max and ready to blow out.

Bravo 1 FS propellers are a combination of adjustments we started doing back in 1998 when I was still at Mercury Racing. So is the XS and OC. These props use adjustments/tweaks we did during Lab processes for the Bravo 1 props for years. We still do these adjustments today as is needed. Point is these props are really nothing new as far as technology but rather marketed as a specific model.
Yes, the FS has a shortened diffuser ring which decreases stern lift and can slightly help trim reaction. It can also decrease or increase planning ability depending on the boat.
No, the propeller does not have additional rake angle.
The rpm difference is aprox 100 rpm higher than a stock Bravo 1 of the same pitch.
The blades are thinned but only from the center forward and are not Labbed to exacting numbers.
BBLADES offers a propeller made from the Bravo 1 casting called our OB/F. This prop has all the features of the Bravo 1 FS, XS and OC in 1 propeller. Here is a link to the OB/F. Also, you can test our OB/F without purchasing it for a test fee of $45.

Just to clarify we have always gained 200+ rpm pitch for pitch with stock Bravo and Bravo factory FS using anything from 28-32, so 1 pitch more will match up at a minimum. I got lucky on 2 different boats and it made 11/2-2 pitch gain at same rpm and same slip (give or take).
Thanks Brett appreciate your input, its always good to compare.

r015,
Anyone who knows me knows......I just report the facts to the best of my ability. That's my job. No BS, just what I have lived and have seen and have been part of. Although some things have changed since I had the reigns of the Mercury Racing propeller Lab, not much has changed.
That being said, all identical boats are different. Been saying that for a few years...or decades too.
The point was deeper.
Labbing to match the boat is the ultimate adjustment prop wise. Bottom line is, if it works, use it.
