I just purchased an Evinrude Speeditwin and I am trying to determine the year of manufacture, but I can’t access the model/year guide database in the Inner Sanctum. Is the database functional? Perhaps someone can point me to another source to find info on my purchase. It is an Evinrude 6039, so it dates from ’39-’50, but I’d like to find the actual year. The serial number is: 10026
