I'm looking at a 1989 Four Winns Liberator 241. It's got a 460 in it and the thru hull exhaust design has those Water bellows to help keep it quieter at Idle I believe. One of the tanks has a really small leak and I was wondering if I could delete these tanks and fab up some stainless pipes and wrap them with dei heat wrap.

These things (not the boat but same design)

What do you guys think?
