            I’m impressed Tubs;  the OMC number did not come up in the interchange that often works.  Did you use the measurements to determine the DASH number or do you have charts that actually show the OMC numbers?

              You got me to look in my files, and I found this GLM
              Seal / O-Ring database, that may help someone.

                My O-ring kit has “R” numbers. Not sure if there’s a cross
                reference to “dash” numbers on McMaster, etc.?

                    Its winter service time here where the temp gets below freezing. This is my back up motor. When ever running a motor for the first few times its in the boat if needed. It gets run some every year weather its need or not and this year it was needed. I may post that motors issue at another time. Checking the lower this year I had some water. Being somewhat frugal I downloading a chart in fractions, and a chart in decimals, which was confusing as 1/8″ is 0.139  on the decimal chart. After a considerable amount of measuring and studying I made an investment of $.79 to confirm that the Dash # 223 – O ring is a match for # 301917 IMO. Tubs

                      The As 568 is the dash # for the O rings in your assortment. Tubs
