I can't find a nameplate on this motor and have scoured the whole motor looking for a model no. and ser. no. but I can't find anything.. believe somebody in the past has spray painted over this info?..or the nameplate has been removed? I think possibly it is a pre-war 5.5 hp. Lightwin? but would like to verify w/ some of you more knowledgable than me outboard specialists..if you can help, it would be greatly appreciated.. tia
