Aw jeez...I bet this question has been asked 1000 times, but I couldn't find it: I have an older (it's painted white, does that help?!) 9.9 4-stroke/high thrust. Where do I a) look for the serial #; b) find the year, when I find (a), and, c) find an owner's manual? Clymer's, etc., don't seem to address the 4 strokes.
