what tabs do you have, what prop a 27 or 28 p? sounds good 80 at 5500 but I bet if you can use a 1050 carb you may find more I change my 850BG to a nickerson 1050 had a good gain I used the same intake with a 1050 spacer. were your tabs even with the bottom of your hull mine are 380s Kplanes set 1/2 or 3/4 '' from bottom ran fine at wfo if you look at pics there not real touching water at 75 to 85 tabs or k planes are good in rough water well keep us posted not sure whats up with my 24 working on the 28.

That sounds normal, it is really hard to make them run fast. Next time you are at the Kaskaskia let me know. I will not be back for a few weeks.
