With the 26P Bravo it is really strong getting on plane. Almost instant.
Tops out at 4800 RPM = 70 MPH
I tried a 28P Bravo but lost RPM and speed remained the same.
I think I should be able to give up a little on the low end to gain more RPM and Speed.

Do I need to have a discussion with Bret before ordering a prop from his site?

Bret is the man to ask for sure. I'm a 3 blade user, and I have tried them all on a lot of boats. each blade on a 3 is way bigger and pushes a lot of water. I think they carry the boats I have better. and they stay hooked up in the fast turns way better. I tried 4 and 5 Blades. each has its place.
