A handful of tugs have reported problems associated with the muffler. Today I got to see a failure firsthand when Pet Tug #60's muffler split apart while the tug was underway. The split occurred along the fiberglassed joint between the unit's top and bottom halves. According to Lou Steplock, there was a loud bang and oily water went everywhere in the engine room. After the muffler was removed only a little bit of fiberglass held its two halves together--resembling something like the hinge on a clam shell. Not much effort was required to get the halves apart. Once apart several things became clearer. The fiberglass tubes, which the exhaust hoses attach to, we're formed around what appears to be PVC. As the picture shows, Pet Tugs' PVC was deforming and small pieces of burnt PVC were found in freely floating inside the muffler.
On Pet Tug #60, where the normal sink and stove positions are swapped, i.e. stove inboard and sink outboard, the galley width is 1" and the Tommy door is 1" deeper.
