    That’s pretty funny. I, too, have a ’68 Evinrude 3 apart.. It has the o-ring also; and I have been down the same road. I was not really even sure if it was OEM, nor could I really figure out what it’s function even was. Nobody uses an o-ring for a crank seal like that, that I have ever seen. I can’t imagine it would last very long as an actual crank seal, when used under high rotational speed, that way. I just finished putting my power head back together with the existing o-ring. I have not run it yet; so I don’t know if that will be a mistake or not….

    Long live American manufacturing!
