That's a 1975 Weedless model. From the era when Johnson model numbers made sense! By the way, that's a Johnson with an Evinrude cover. It doesn't matter though, they were exactly the same except for paint and decals.

The original fuel mix from OMC is 50:1. But many, including myself have found this insufficient for this particular outboard. I would rather use 32:1 with 87 octane gas and TC-W3 outboard oil. See the Oil Mix FAQ in the FAQ forums for details.

[Hey Admiral,
Thanks for the very helpful info.
Thought it was a 1975, but wasn't sure.
Appreciate the info on gas/oil mixture.
I'll give the 32:1 a try .
