If you look at the attached photos, there is a fair amount of corrosion (pitting) on the exhaust pipe, but not much on the manifold.
My take on this is that the exhaust connector (the rubber bellow) was in this case installed a tad too far down on the "pipe", allowing water to pool up inside the connector and just "sitting there", slowly eating away at the exhaust pipe. I guess it would have looked a little bit different if the "bellow" and clamp would have been sitting a little bit higher.
Hence, it you have a vertical connection, or a connection where water can "sit", even after flushing, see if it can be easily correct as suggested.
BTW, this is on a freshwater boat, or a boat that has seen salt water but always has gone through at least an hour of fresh water (locks and canals) after having been in salt water.
Now I just gonna fight those four small allen bolts to see if I can get the "nose" on the manifold off.
