I've recently acquired an older Evinrude 9.9 that is in running condition, but could use a bit of work to get it in tip top shape. The problem I'm having is the the serial number/model plate from the port side is worn off, and I can't figure out the model number. By looking at the engine I know it's in the 1974-1976 ish range. I was able to get the number off the metal disc that is stamped in the powerhead. That number is C0065718, however I can't find anywhere (in online searches) to cross-reference that number to determine the exact model number/year of the motor.
Does anyone know how/where I can cross-reference that number to determine model and year?
