Howdy, b hunter.

Welcome to iboats.

All OMC outboards from 1964 up use a 50:1 mix. Yours is a 1977, so it will use the 50:1.

Good luck.

Re: fuel oil mix

If you find that the motor is too smoky, you can also use the Synthetic Amsoil Saber at 100:1 in any 50: motor. One half-pint bottle per 6-gal tank, instead of a 1-pint bottle of "regular" oil per 6 gallons. Less oil means less smoke. I have done that for years in my 1974 Evinrude 15. Since it's half the oil, running the Amsoil was actually cheaper in the long run.

Re: fuel oil mix

Back in the seventies McCullough also had a 100:1 mix oil (red oil) and they were shortly out of business ... LOL

Many say they have been using this Amsoil Saber for some time ... I only used it for a tankfull (maybe less) and I hated the stinking smell (tiller)
