Jim,
I went with a very small Vernalift muffler. It is fiberglass and should last the life of the boat. It is quiet, but has a nice warm note to it as well. It's a mellow sound that is pleasing to my ear. I've run my engine without the muffler attached. It may smoke a little bit, but what's worse is the salt spray that it throws everywhere. I don't recommend it.

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.
