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.
 
If its not done! I would glued this bearing OD and ID whit green locktight.

Bearing , I did mine whit air first. Then brake cleaner amd Lots of Air again .
I always used Blue amsoil full synthetic .

Would Mobile 1 synthetic work or should
I use the iso flex suggested above ?
 
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.
