Hey folks, after pulling the 460 big block out to do some maintenance, I have determined that the rubber coupling that connects the exhaust riser (starboard side) is about 1 1/2 inch offset from the exhaust hull outlet while the port side is virtually straight through. The length of the coupling is about 5 inches. When I purchased the boat, it had a makeshift coupling attached which did not fit correctly. Does anyone know if there is a coupling that is offset and designed to fit this craft? Been searching the net with no help to be found. Hope I can find the help here!
