OK. I am so slow. Was looking for a serial number series for each Johnson model. I am understanding now that a given
serial number is only used once no matter the model. Just didn’t get that in my head. I do have the Old Outboard book but
thought that the total number of serial numbers did not represent specific models. Thank you all for your patience. But now
I can go back to my Johnson collection and figure their year. Have been wondering that for long time.
