Everything on the motor needs to be checked by a good mercury mechanic. My advise would be to take it to a good dealer like rockwall marine and have it checked out, boat and outboard before you spend your money. A couple hundred spent on check out could save you thousands and most important peace of mind. Great boat and outboard seller seemed to be honest about it but have it checked out first.
