Between the bellow and the bell housing? Yes.

Sand clean the surface on the bell housing and wipe with acetone and YES use proper adhesive.Charlie

Lacquer thinner makes easy work of dried bellows adhesive. well worth the cost and trip to store. Acetone didn’t work for me

recommend allowing bellows adhesive to cure for 48 hours before stressing the bellows. I was able to slide exhaust bellows off one side when attaching the other, even with properly torqued clamp. After letting one end cure, it was simple. Be patient if you have the time.

I didn’t use bellows adhesive for the ring side (bell housing side of I joint. I used it on both sides of exhaust bellows, front of I joint bellows and on shift cable bellows.
the ring is easy to install with the tool. Maybe I missed it, but the manual doesn’t specify it.
Just make sure the bellows lip is pushed firmly i to the groove and notice the beveled edge on the aluminum ring. It’s just wide enough to squeeze into the bellows when drivin in with tool.

If thinners is needed to remove old adhesive that either means you didn't sand properly or didn't sand at all.Thinners will not promote adhesion however acetone will.Probably the reason that your glued on bellows slipped off. Charlie

I used lacquer thinner to remove old adhesive. then sanded bonding surfaces, then acetone to remove residue.
My point about allowing it to cure before stressing, by experience, stands

do yourself a favor and get a factory service manual (merc manual #14 for gen 2 drives)

While the answers above are correct - the manual will have all the detail on this and any other repairs, any special tools, What lubes , sealants etc are used where

my manual states to apply bellows adhesive only on the transom ride of the UJ bellows, but i did a ton of research and found that best practice is to put it on both sides now. The thought process is that the surface of these old gimbles can be porous. and the adhesive helps seal.

The issue with applying to both sides is that you will not be able to adjust the bellows before clamping .With both surfaces being coated it becomes glued on contact so you have to get it on perfectly the first shot at installing it..THAT I dont like. Using the adhesive on 1 surface will allow any adjustment needed before clamping. Charlie

Note exactly the orientation of the hose clamps, as they need to be in the proper place not to interfere with the bellows, hoses, cables, etc.
