Well the problem that I have had with my previous props is maintaining that speed. I can run 70 mph with a 26p bravo 1 xs but those props are very thin & you will wear the cupping off of them very quickly running in skinny water (marsh). The hole shot is amazing as well as acceleration & top end but I put a brand new bravo 1 xs on my boat last year & wore the cupping off in 4 days. Dropped from 70 to 64. I did a little research & found out that the 27p bravo 1 xs is actually the same exact prop as the 26p, it just has more cupping. They both come out of the same mold. So I got a 27p & I get the same top end speed but less hole shot.
I did more digging & ended up buying a Turbo TXP OT4 24p prop. Much thicker blades, holds up way better in the marsh. Running 68 with it & hole shot is great but i still lost top end over the bravo xs.
Mercury has been working on this pro max prop for the last 18 months & it's supposed to be a much beefier prop that will not tear up when running in skinny water & still have the performance of the bravo 1 xs.
Looking forward to running mid 70's with this thing.
