    Yes, 16:1 is the original oil mixing recommendation for this engine.  Ignore all the hype, even some bad info from OMC in later years, about mixing 24:1 on this engine.  This engine has “plain rod bearings”, no roller/needle bearings.  Run it light on oil and a rod usually finds its way out of the powerhead!
