Hi Cron. Regarding the O ring missing on the drive shaft, it is most important that you have put in a replacement!!!!
It stops water getting in and ruining the crankshaft spline. I have a 1964 3hp Johnson that had a ruined crankshaft spline, all because someone failed to make sure one was installed
during servicing!
Make sure too, that the drive shaft spline is well greased when reassembling. As for remnants of an O ring being still up on the crankshaft spline, I think that would be fairly remote.
Shine a torch up and may be use a piece of wire to check.
I got a replacement from my local auto supply store for just a few cents…….,..take the drive shaft with you to get one that fits well.

Hope this helps.
