MattinOK Posted August 13, 2010 Posted August 13, 2010 I just bought a 14ft. aluminum vee-bottom, with a trailer and 9.9hp Johnson Seahorse for $500. I got the motor in a barrel today, and it started on the first pull. It runs like a champ, but I can't figure out how old it is. We don't have to title any motor under 10hp in OK, so the only thing I have is the model number. 10R74S. Quote

Best guess 1974 Mine as well, since it is a johnson I believe they usually put the year it was made in the serial number. That's how mine is. You can also take that serial number and put into google and it should pull up some info just to verify. Quote

Thanks for all the replies! Quote

Super User Way2slow Posted August 13, 2010 Super User Posted August 13, 2010 Try this http://epc.brp.com/Index.aspx?lang=E&s1=c8f6ffad-d847-46d7-ac0f-5f62fd592abf Go to the pull down, click on Johnson Go to 1974 9.90 and click on it. I think you will find you're motor there Quote
