OK.  Got the Yamaha F9.9 20" shaft motor, with 8 1/2 inch x 6 1/2 pitch, properly mounted into well on my 7.6 Kelt.  The boat bottom has 3 years of growth on it.  But I feel like there is too much ventilation happening at any RPM. High revs don't give boat any more speed, thrust is poor.
If there weren't so many other 7.6 Kelts out there with 20" shaft motors I would say the shaft is too short.....now what??
What pitch are other owners using, is pitch the problem, 8 1/2 is what the motor came with, past owner changed it not sure why?
