So far I have seen three different fuel ratio mixtures for our 1970 Evinrude OB 9.5HP 9122r motor. Someone with an owners manual please tell us which one is right 50/1,32/1 or 25/1?? Thanks

50:1 87 octane gas to TCW-3 rated outboard oil.

OMC changed all their engines from 24:1 to 50:1 in 1964.

And welcome to Iboats!
