I am going through my 165 mercruisers (Chevy 250 L6, 4.1L). The manifolds and risers were rotted so I replaced them along with all the gaskets. Both shutters were missing so I am replacing those. The upper bellows are leaking around where they attach to the exhaust elbow. This is the bellows that is inside the transom. Its a rubber tube from the riser downpipe to the exhaust elbow. The rubber bellows were in very good shape so I did not replace them but the exhaust elbows are somewhat corroded. Unfortunately it does not look like the elbows can come out easily without pulling the motors. I assume this junction is leaking because I did not use any bellows adhesive and they cant seal because there is no-longer a smooth surface on the elbow due to the corrosion.
What I'm asking is should I be using bellows adhesive here (see photo)
