Abstract
An exhaust system for a marine exhaust system includes two riser conduits, each being connected to a Y-pipe at an outlet end. An inner tube of each riser conduit directs exhaust gases through a catalytic converter assembly and into the Y-pipe. An outer tube surrounds each inner tube to define a cooling liquid passage between the inner and outer tubes to direct cooling liquid into one of the inlets of the Y-pipe. A bellows couples one of the riser conduits to one of the inlets of the Y-pipe. Each bellows surrounds one of the inlets of the Y-pipe and one of the riser conduits. To minimize reversion, the inner tube of each of the riser conduits extends into one of the bellows further than the outer tube of the respective riser conduit.
