i need the carbs rebuilt on my inline six, does anyone know an average cost to have this done? if i have a repair manual is it difficult to do myself?

get the kits and manual here on iboats, get new floats, don't come in kit. Do it yourself, very easy.

easy if you got the right tools and knowledge. I just finished my 1986 inline 6 and was not the easiest carb job. although after I was done yes it was easy. Just finding the right 1/4 drive socket was annoying, and adjust the butterflies was a little tricky. What does the manual say for the idle screw adjument?

idle mixture adjustment is a bit tricky, until you know the secret and have some patience and calm water to adjust it. Set the idle mixtures to 1-1/2 turns out from lightly seated. Launch, warm and run the motor in the lake/bay. Adjust the idle screws a bit at a time to achieve smoothest, fastest idle speed. Now try to accelerate. Normally the motor will stumble, due to being too lean. Open the top carb 1/8 turn and try to accelerate. Repeat with mid carb, and then lower carb, testing acceleration after each adjustment.
