I have a 9.9 johnson on a small fiberglas skipjack 10' 2 seater for my son. the problem is it will not plane with two people (sidebyside seating) Changing the carb seems to be too expensive verses the outcome. Can anyone suggest a prop change that will get this lil guy outta the water faster with two people?? I do not have a tach or any means to determine rpm's and I am sure this is the original prop.<br />Thanks
