    I will try and contribute if my message doesn’f go poof

    In the July 2009 “Outboarder” I wrote an article about these O rings, showing sizes of the various options available and a suggestion for modification for a better fit. I pulled the old issue and see that I added a sticky note about the #107 ( McMaster #9453K – 169) rings These measured .412 OD X .206 ID X .103 W   an original OEM ( pre 1960 ) that I had measured .404 X .172 X .125 . If you have the old issue , check it out
