I have a 2007 Mercruiser 5.0MPI with a Bravo III drive. It's my understanding that these have a "sealed u-joint". Not sure what that means exactly, especially if you get a tear in the bellows or something. I've done a search and can't find much information and I don't see much in the manual either.

a "sealed u-joint". Not sure what that means exactly
while i ain't the pro here. to me it means. it's prelubed and there is no accommodation for putting new lub in.

if you have water intrusion into the bellows. i can't help but think. R&Ring of ujoints is expected. pre sealed or lubbable. rust is rust and they'd have to go..
