      I have 3 sizes of rings that I am having a hard time finding the applications. Came from an OMC dealer

      First PN 101267
      Right about 1.75" when fully compressed and 3/32 widens square end with no provision for a pin

      Second size,no PN
      1-5/8 x 3/32 with cutout on the back side for a pin

      Third size, no PN
      1-1/2 x 3/32 with a relief on one end for a pin.

      Left to right in the photo. If anyone knows of some application, please let me know. I have a feeling they may be pre 1950 Evinrude based on other inventory.

        Here is what I have. The 101267 is for the apposed 3.3 horse Evinrude Sportwin/ Elto Handitwin. The second might be a 278303 for the 3.3 horse alternate firing Sportwin. The third may be a 200547 for the Evinrude Zephyr.

          Thanks Garry,that is very helpful. They are more likely to get used as needed now that I know what I have.

          Thank you.
