Gimball ring being rubbed my bravo drive without rub plates
I just got a call from my mechanic and they are telling me that my older starboard drive doesn't have rub plates on it and has rubbed down the gimball ring about 1/4 in. They are wanting to know if I want to replace it while I am in there tearing this thing apart. I don't see that this could really cause any mechanical issues. Does anyoen think I need to bite the bullet and do it?

Keeps your drive centered with the gimble bearing. Not to say how much is too much that the U-joints can't handle, but take in account that some support strength has been lost. Whats another $1k?

It's normal wear and tear, thats why Merc started putting wear plates there on later drives. Depending on prop rotation it loads one side of the drive/gimbal ring and as you trim while under power the aluminum wears.
Ron Bender (JR Marine) fixes that. Looks like it will cost you $75 to have them build up the area and machine.

Hinge pins on the low performance transom assy will loosen up and cause excessive wear. The one without the wear pads will get worn down.. If the drive can swing too much due to excessive clearance, things can break. When a gimbal ring or bellhousing break, bad things happen. Been there, done that. 14 months with double vision.
I would suggest you get it fixed. The J&R repair looks like the best best. Depending on how much wear is on the drive housing, and there is some I would suspect, that would be a subject to bring up with J&R.. I would think you could add the wear pads to an old style with some work on it. But I have never done it.
I would do something to resolve this, and not just let it go. It will turn out bad if you do.

I had same issue on my alphas...Rubbing on the gimbal ring...pins appeared to be tight. I didn't have rings out and used PC-7 epoxy to build a "temporary" wear pad.
It appears to wear better than the Aluminum and have been in place for 5 years or so.
If you have it apart welding and remachining is obviously preferred...or installing a bolted shim.
