Popped the seal. Do I add any grease?

I would, but try to remove most of the old stuff first.
And do not put too much grease in, or it will be forced out.

What brand or kind? Looks like a dry grease unlike the the other drive bearings.

Pop it off. Takes an hour max. Can repack the bearing and clean things up while you're at it.

This is a very high-RPM, high-load ball bearing application. I'm not sure Mobil 1 is designed for such an application? I think the Doo crank bearing grease IsoFlex would be a better fit.

That bearing is high speed and high heat. I doubt normal grease would be appropriate.

I tried finding another type of bearing for the pto. I believe skf made one but once i told the guy the expected rpm and heat he indicated i better stick with the spec bearing from Yamaha/koyo.
