Challenger Exhaust Hose

[moreschi]

Hello. I can't seem to find the exact part number for the exhaust hose that I need. The schematic drawings for my model jetboat look different than the engine assembly that I have. The boat is a 2004 Seadoo Challenger 2000 with Mercury Optimax 250 hp jetdrive. The hose is one of the 2 that come from the engine and go to the exhaust that exits in the back of the boat. It is about a foot long with a metal tube about 6 inches long inserted into the hose. Thanks
