As a new boat owner with a 48 Evenrude Special, I had it winterized at the marina last year. He now tell me I need a tuneup before I put it into the water. what does a tuneup require for this motor. I had new plugs put in the middle of August and the carb cleaned by the people who I bought the boat from. Can I just put the boat in the water and run it after it was fogged or is there something I have to do?
