I have a 7 HP Eska Federal outboard. Vintage circa 1970.

Model is 1772B

SN is 200230

Asfar as I can tell this motor needs 16:1 or 24:1.

Anybody know for sure?

Thanks

The 1772B is a 1972 model. Eska called for 24:1 mixture (pint to 3
gallons) of 2-stroke(non-TCW) oil. If you are using TCW-3 oil, 32:1
should be sufficient, which is what Eska switched to for the 1974 &
later models.
