Claim Text:
1. An apparatus, comprising: a marine genset including an internal combustion engine and an electric power generator mechanically driven by the engine; an intake system connected to the engine for providing a charge flow to the engine; an exhaust manifold connected to the engine for receiving exhaust from the engine; and an exhaust gas recirculation (EGR) system configured to receive exhaust from the exhaust manifold through an EGR inlet and an EGR outlet to provide exhaust flow from the EGR system to the intake system, the EGR system including a housing defining a plurality of exhaust flow passages in fluid communication with the EGR inlet and the EGR outlet, wherein the housing further defines an outer cooling passage portion around the plurality of exhaust flow passages and at least one inner cooling passage portion between the plurality of exhaust flow passages, wherein a cooling fluid circulates through the outer cooling passage portion to reduce an outer temperature of the EGR system while reducing a temperature of the recirculated exhaust in the plurality of exhaust flow passages during operation of the engine.
