Correct fuel mix?

[Scooterdude19]

Hello all. I just picked up a 1965 Evinrude Sport Twin 9.5 horse, model #: 9522C. Can anyone tell me what the correct fuel ratio is, and if NMMA Approved TC-W3 is the correct oil to use. Thanks.

Re: Correct fuel mix?

you are correct on the oil, the ratio is 50-1 spark plug should be Champion J4C gapped at .030 if you are going to be doiing a lot of trolling you can open the gap to .040.
