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. I run an HVAC contracting business (when I'm not fixing the boat He he)Jim

If your hose is original you might want to replace it now while one end is off. BTW, fiber optic camera? Very cool!

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).

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.
