I did go with the RPMs.

But today I just ran the engine, the drive is currently off.

I was going to pop the drive cap, but I've not had that off before and I'm not sure I could accomplish anything! The drive shaft and U joints look good, and turning it by hand there are no weird noises/clunks/grinds/ to be heard. I'm thinking of putting the drive back on in a tub and seeing what happens.
Ayuh,...... Is there any metal in it's oil,..??
