Abstract
Method and arrangement for a marine combustion engine exhaust system. The arrangement includes at least two substantially upstanding exhaust pipe arms that are coupled together in common closed fluid communication with a stem exhaust pipe. A pressure equalizer is fluidly connected between the upstanding exhaust pipe arms. The pressure equalizer is configured to provide sufficient fluid passage from each exhaust pipe arm to another to prevent flow back of sea water to a marine combustion engine associated therewith.
