I am a first time boat owner & purchased a 2000 starcraft 160C it has a 2000 Merc 75 HP 2 stroke outboard. The motor is very loud and it smokes a lot. I had a friend check it last year and he was of the opinion that It needs a tune up. Since then he has moved out of state. It has carborators, do you know of anyone who can help and is reasonable. I was not aware I had to winterize and hopefully no damage has occurred. Any help will be greatly appreciated.
