Is this how you measure prop shaft runout??

I measured at the very end of the shaft and that reading would be higher.

Ayuh,... Your link says "Photo not found"...

Propshaft run out is measured at the very End of the shaft, aft of the Nut...

Try the link again. Should work this time. Video shows near the seal.

I would measure both locations, you could have a bend right at the spline that may not show measured at the seal location? I don't know for sure if it could happen just err on the safe side.
If you had excessive runout like .020 I'm wondering if a guy could slip something over the splines for protection and whack the shaft with a deablow hammer and bring it back to within spec. Not condoning it but that's the stupid stuff I do sometimes and I learn from my mistakes. I mean a good whack on a rock or something is what bent it in the first place so why not a whack in the opposing direction?

You know that not a bad idea. I couldn't make it any worse. I have a heavy rubber mallet I could use.

I gave it a couple of smacks with a rubber mallet and a 2 lb sledge and doesn't move. If I hit it harder to get it to move I would surely destroy the lower unit.
