    Suddenly lost one cylinder

    I have an Evinrude 90hp 1990. I've been working on the boat on land for a few weeks. It has run pretty well for the most part. A pop and stutter now and then at low rpms (on land pretty much all I do) especially when not really warm. I have started it and adjusted things many times over the...

    It was running ok when I left town for week. My wife ran it at low speed for 3 minutes (across a lake). It would not start. I started it when I returned, but it runs very rough at low RPMs. Won't idle, I have to drop the fast idle and slam it into gear. I got the boat a couple of months ago...

The first three characters of the HIN are for one manufacturer and they expected characters for the actual boat are different. Still looking for the HIN on the hull. Have...
