I greased all that well. Does anyone ever put a sealant on there instead for older bellows?

It really depends on conditions how long they last. I've had 5 yrs on one set, but replaced them 2 yrs later after the boat sat on the hard for a few months and they looked brittle.
Ive always used bellows adhesive on the driveshaft and exhaust bellows. Not so much as a sealant, but to be sure they set properly while I clamp them down.
I'd be leery of grease on any of those connections. The castings are usually tapered a bit and you really want the bellows to stay put. That's a big hole below the waterline if one fails or slips off. (Referring to driveshaft bellows)
