Picking one up this week, it hasn't been run in 10 years or so, but has been stored indoors.<br /><br />What are the first things I should do, aside from getting a manual? Owner said he changed lube before storage and drained carb because it was in his basement. Impeller kit and new lube??? What else?<br /><br />Forgot to mention, 1973 serial #3667961, this number does not appear on the Mercury Web Page. Could it be wrong?
