hey all, i just bought a 2007 mercury 60hp 4 stroke efi. i purchased it from a used outboard dealer and took it out for the first time today, it will start right up and idle great, but soon as i try putting it into gear, forward or reverse it will hesitate and sometimes die out. Even if i am running at low rpms trolling 1 to 5 mph it seems to hesitate some. When i open it up it will run fine and wont miss a beat. and some other times it troll and go in and out of gear fine. I know the motor sat at the shop over the winter at leat 5 months. There is a new fuel filter in it and clean gas in my tank and i tried 2 differnt tanks and lines. I am sort of thinking that it may just have some slight buildup internally. any suggestions will be greatly appreciated. i was wondering if putting some seafoam in the gas will help clean it up some and maybe solve it, but this is my first 4 stroke efi i have ever owned and dont know if this is the right thing to do or not. please help, thanks.
