Abstract
A pump jet apparatus having a double-walled stator housing containing an annular passage through which exhaust gas can flow. Gas enters the annulus through an exhaust gas inlet or port formed in the outer stator shell at the top of the stator housing, flows in two streams around the annular passage formed between the inner and outer stator shells, and exits the stator housing through exhaust outlets or ports formed in the outer stator shell near the bottom of the stator housing. The streams of exhaust gas and impelled water flowing through the stator housing of the pump jet are kept separate by the inner stator shell.
