I lost about -5 with a Cresent Drive. Went from about 90 to 85 and an occasional 87 very light and by myself. I proped from a labbed 30 bravo or standard 32 to a standard 28 bravo

I put xr lowers on and took the Bmax's off I lost 6 mph with the same 5 blade props. Now that I have the Bmax's fixed so they don't leak I have them back on and the speed is back.

I went from a modified 32" Bravo I to a box stock 26" Bravo I and only lost 2 mph on top and cruise speed stayed the same.

They seem to be working fine for me. ;)

Dean Now offers a 1.5 Ratio. I Ordered a new B - Max to replace my 1.5 ratio XR with a B-Max 1.5 Ratio and have no Speed Loss.:evilb:

I went from a xr to a scx and lost 0 mph. That is the way to go if you want strong and no speed loss. Just my 2 cents
