That to me is a weld repair...it looks like it cracked on the weld. You just need a good guy that can weld thin material...First repair needed on my 2008 48. Port side "Connection, Exhaust Outlet" (Cummins part # 3978849) which is the elbow coming out of the turbo. It developed a crack and is leaking. Does anyone know of an aftermarket supplier for these? Cummins wants $4600, DeAngelo is half that but I was wondering if the Sea Ray community new of place for replacement or used parts. It's aluminum so can it be tig welded? Thank you.
