The original stainless steel muffler failed on my 1980 Hunter 33. The original muffler is 18 inches long by 5 1/4 inches diameter with a 1 1/2 in OD set of ports. The muffler just fits under the 20 gal fuel tank. Does anyone know an equivalent replacement for this size muffler? Note, the exhaust elbow for the 2QM15 engine is 2 in OD. It appeared that a small piece of 1 1/2 in ID hose was fitted over the orginal 1 1/2 in muffler port to make for the difference between the 2 inch ID hose that connects the engine to the inlet port of the muffler.
