    The Parts Reference Guide from 1965 has an oil chart that lists all QD models at 24:1.

    Generally pre 1964 24:1, pre 59 20:1. 1964 onwards 50:1

    See http://www.evinrude.com/en-US/Owners...FAQ/OilAndFuel

    There are motors later than '64 that do not have needle bearings that are best run on 24:1 and there are earlier motors that do have needle bearings that could safely be run on 50:1
