I have what I believe to be an '86 5HP Mercury Mariner branded Yamaha outboard. The transom clamp tag is gone and I am going by the cowling decals. The Engine is cast with 6E302 with the welsh plug stamped 138041. Hopefully the images show on the post. I am looking to register my dingy this spring and would need the relevant model and serial number, but I am not able to find a cross reference with the stamped number. Any guidance would be greatly appreciated.
