      Hi,

      Does anyone have the specs for the crankshaft that goes in the ’62-’64 OMC 5.5 motors and the 6 HP that followed? My manual just says “bearing type” in the specifications for the big end of the rod. I have one motor that was pretty loose on the big end and would like to know if my crank is still in spec and I can just replace the bearings and liner. I have a new rod to compare the big end ID.

      Thanks in advance,

      Adam
