Sealing Tunnel boots is always a tough job.
repairs done to metal are tough and seeing it clamped properly is difficult
I like to take 2 days to install. Day 1 put bellows on with some silicone and let seal, day 2 put on clamps. use mirror to check
Water test with no seat in after any bellows work to make sure job is 100%
Many years ago I took a car in without checking, in a gator infested river in FL.As we came out I hear the water sloshing and looked underneath to see it pouring out of the shafts.. Boy was I lucky!
Volvo Penta makes a slightly larger bellow(part # in my Parts List)
that is very flexable and easy to install.
