I just bought a new muffler (vernatone inline) for my Hunter 1981 36. I am astonished at what West Marine wants for exhaust hose. Any "cheaper" ideas. Jamestown Distrubutors seems to have the best prices but I am unsure of what type of hose to go with. The I.D. is 2" and the length is about 10ft. The engine is a yanmar 2qm (18hp).
