As a part of our annual engine maintenance tasks (new zinc in the heat exchanger, new oil, new oil filter), everything gets a general inspection/lookover. Behind the engine, in a nearly inaccessible space, is the exhaust hose and the waterlift muffler. Note the white salt deposit on the outside of the exhaust hose... Close inspection reveals that the hose is bubbled up at that spot.
So what's happening? The hose has failed. Ply separation has allowed the seawater in the exhaust to penetrate the hose, all the way to the outside. And since the hose is reinforced with steel wire, that has undoubtedly turned to rust.
It looks like I have some boat yoga in my future...

Better to find it now than while you're 100 miles from anywhere in 60 feet of water...
