Yamaha 220hp problems

[bigrodthebasspro]

I am having out of my yamaha 220..Well, it has a real hard time comming out of the hole and when it is up on pad running, it has a miss in it.....Well I took in to have it worked on. Today makes a month since the shop has had it....I have talked with the owner about 2 times a week. He has no clue...He did tell me that he ruled out all electrical problems. What do you think? What would you check? Recheck?Could it be something in the fule system? etc.... I would really like to have my boat back before the summer is over....

Thanks for your time....
