This old boat (C&C 27 MK II) has an Onan water lift muffler that is 12" diameter and 12" high. It has a side entry and center vertical exit. The base of the muffler is just above the base of the engine, so the manifold outlet and muffler inlet are almost on the same level (the pipe has to have a vertical loop built in).
The MMI SS muffler is only 6"x7" -- half the size. The hose run from muffler to transom is about 8 feet I think, including a 2-foot vertical rise before sloping back to the transom. So, would the smaller MMI muffler work?
