If you are in the Louisville/Shephardsville area and want a mechanic to check it out, take it to Reynold's Performance Marine. Tony, the owner/mechanic is awesome. He is a Mercury guru but just about as good on Yamahas as well. I am not in no way associated with this business just a happy customer. I am very particular about how and what is done to all my mechanical devices (car, boat, lawnmower, etc.). So I am sure you will be satisfied with his work. It WILL run right when he gets done with it.
