We use the fiber optic camera to inspect home heating system heat exchangers
for cracks.Actually they are pretty cheap, I've seen them for about $125 -
$150. very handy for many hard to see places, inside walls, etc.

If the break is on the top side of the hose exhaust could be leaking into the
bilge. If your hose is original you might want to replace it now while one end
is off.
BTW, fiber optic camera? Very cool!

Joel,Wouldn't I see leakage(water) at the clamp? Hoses are dry. Are you

Jim,
You might check the exhaust hose carefully. A small break around the clamp
might give the same symptoms, and I bet it is a cheaper repair (if you can
crawl in there).

Follow up to my loud hissing sounding exhaust. Raw water system good, flow at
end of heat exchanger going into the mixing elbow strong. Looked inside of
mixing elbow, no blockage(aided by flexible fiber optic scope). I didn't want
to run the engine with exhaust hose off of the elbow. figured it would make a
sooty kind of mess in the engine compartment. So I've decided the lift muffler
must be the culprit. Outside jacket showing some spots that look like its
rusting thru from the inside out. Perhaps inside baffling is deteriorating and
causing blockage? In any event looks like a potential fill the boat with water
issue. As I stated earlier the engine runs ok, no overheat condition, didn't
really notice lack of power.
Any other thoughts? Looks like Defender has some good prices on veralift units.
They also have a Vetus model twice the price looks like its a composite
material.Listers any experience with either?Thanks as always.
