Good God that's scary. How old was that hose?When we purchased our boat the surveyer recommended changing out raw water pickup hoses. They were in less than good shape. I went through and checked all of the hoses. This was the bottom side of our starboard exhaust bypass hose. It came apart while I was trying to remove it. Don’t think I would have seen it if I couldn’t fit behind the generator. Doubt any paid maintenance personal would either.View attachment 77578
