Could anyone tell me what the correct fuel/oil mixture is for this motor

thanks

It probably calls for 50:1 like most outboards. I had a 1993 Evinrude that tended to oil-foul the spark plugs when I mixed it at 50:1 so I cut it back just a little bit to 55:1 or 60:1 depending on how I felt on a given day. It had oil injection, but the previous owner didn't trust it and disconnected it (likely for good reason), so I had to mix the oil.

definitely 50:1 should be the right place to start with your motor.
