. interested in whar size everyone has. my hoses leaves at maybe 4". it has a smaller hose inside a larger. it would seem to me the elbow is 3.5 inches the hose in increase to maybe 4.5 at the muffler then reduced to 4" to leave the boat. it would seem to me a 3.5 aqualift increased to 4" would be correct.
Thanks
