I have recently acquired an 9.9 hp Evinrude with a boat I purchased. The guy said it was a mid-'70s model. The problem is the ID plate has a big gouge in the model #. The Serial Number is clear. I'm having trouble getting it to start, and I'm afraid I'm going to need parts. Problem is, I don't know what model it is. Any way I can get the Model number using my Serial number? Any help would be appreciated!
