I just bought a boat and the outboard is missing the tag with the serial#. The guy said he thinks its somewhere around a 1990 Evinrude 35HP 2 stroke. I found this number on the little disc on the engine block also- G3233314
Might need to see a photo with the cover off and another of the cover.
Sometimes there is a plate on the side of the transom fitting, ie the bit which joins the motor to the boat. Removed in many stolen ones:hat:
