      Not having a parts list for my little Johnson MD38 to look up piston ring
      parts number, I found an Evinrude piston ring chart showing rings
      for pistons of the same bore and ring thickness, of the same era.

      When I went to install them today, I was disappointed to see that
      the new rings were wider in “depth, by .020.
      I cleaned the ring grooves, and tested the new ring, and they
      seated with room to spare. Also checked end gap and decided
      it was okay.
      Also different, the Evinrude rings I received were for a “pinned” ring,
      the Johnson wasn’t.
      I went ahead and installed the new rings and put the piston in the powerhead.
      So far all is well……. then again, I haven’t started it yet.
      Am I looking at disaster on it’s maiden run?
