Abstract
An exhaust system for an outboard motor wherein the exhaust pipe which depends into the expansion chamber formed in the drive shaft housing is provided with a separate cooling jacket. Water from this separate cooling jacket is discharged into the expansion chamber at a point well below the discharge end of the exhaust pipe in a direction away from the exhaust pipe so as to avoid water ingestion into the engine through the exhaust system. A second expansion chamber communicates with an above the water exhaust gas discharge. This second expansion chamber communicates with the first expansion chamber through a restricted path formed in part by a flange of the exhaust pipe.
