Hey y'all! I have read almost this entire forum looking for an answer and I cannot find anything. I need your help. I have a Johnson 115 and I cannot find a model number. The plate on the transom bracket is missing and I found a freeze plug on the block, but it looks like it was painted over and then scratched off. So, no numbers there either. I've looked for brochure pictures and cannot find a match to what I have. The previous owner "thinks" it's an 81, but I would like to know for sure so I can get a service manual. Is there any other way to find out the model number? Any other place I can look? Thanks in advance for your help.
