Can a labbed 25 run 80 on a 311

I would say its possible but you would have to be turning them over 5600rpms (guess of top of my head) and have pretty low slip #. What rpm you turning? I get 75-76 at 52-5300 rpms non labbed 25's in a smaller boat.

If you can spin the 25's at 6000, have a real slip factor of 15%, you would in theory run 80.492423 MPH !!! It's all in the math.

13% slip (a good # for that hull when set up well) would require 5826rpm to get 80mph
