Just purchased a 16ft boat with a 50hp Merc 500 on it. Judging from the serial number (1600913) I'm guessing it's from '63 or '64. Anyway, I was just curious as to what fuel/oil mixture was recommended for this motor. I am also looking for an O&M manual for it. Unfortunately, I do not have any marinas or boating supply stores nearby, so I am stuck searching online. Thanks in advance for any help!
