My 85 272 would run 60 at 4800 RPM with cleavers. You have too much prop or your motors are tired. Also Formula had a performance option that had a higher than normal X height. The early 83-84 models had a fairly big rocker in the hull. Check on the Formula forum.

Like F311 said.
Run cleavers. I have them on my 85 Formula 272 LS. 60 MPH.
23" pitch.

I would also try A pair of 21 Mirages Or 23 Mirage. My 87 272 would spin the 21's 5000 but i lost 4 mph I ran the 23's Spun them 4500 @59.99999 my cruse was 40 at 3200.

My cleavers were 21 pitch. The bravos need to be 3 blade.

23 is too much pitch. You need 21 pitch. Contact Julie at Throttle Up. They advertize on here.
