Lots of good replies here, thank you all, you guys are awesome.
So a few things:
Yes there is a flat on the hub that corresponds to that on the crank. I do have a prop nut and prop washer, they're just not in the photos. It sounds like a suspect bearing, and I will look into ordering and replacing. There is also a thrust washer in the picture, although it is a bit dark.
Anybody have a link to the specific Boca bearing I need? Seems like there are several options...
Thanks again to all for your help.
