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. <br />OMC changed all their engines from 24:1 to 50:1 in 1964.<br />And welcome to Iboats! :)
