Hello Everyone. Had a question I was hoping someone could help me with. I have a 1978 Mercury Classic Mercury 900 90 hp that I just tuned up and got running but I'm not quite sure what the gas to oil mixture should be. It's about out of gas and I haven't got a clue.
Thanks.

Does that's also apply for a '77 Mariner 85 hp? I was just about to post a thread to ask.
