Abstract: A heat shield includes an outer jacket including a fluid inlet port and a fluid outlet port, and an inner jacket nested within the outer jacket and spaced apart therefrom to define a fluid passageway therebetween. The fluid passageway is in fluid communication with the fluid inlet port and the fluid outlet port for directing a cooling fluid from the fluid inlet port to the fluid outlet port through the fluid passageway. The inner jacket at least partially defines a main cavity configured to at least partially protect a turbocharger of the marine engine.

Abstract: A jet pump includes a propulsion system including an impeller coupled to a rotatable shaft configured to receive torque from an engine and an exhaust system including an exhaust flow path configured to direct exhaust from the engine to an exterior of the watercraft, wherein the exhaust system is integrated with the propulsion system. In another embodiment, a jet pump includes a propulsion system including a water intake configured to take in water from a body of water, the water intake including an intake grate and an intake base, and an exhaust system including an exhaust flow path configured to direct exhaust from the engine to an exterior of the watercraft, wherein the intake base of the water intake is configured to be coupled to an exterior surface of a hull of the watercraft.

Abstract: An air intake and exhaust system for a marine engine having an intake manifold and an exhaust manifold includes an air compressor configured to compress ambient air into compressed air and a catalytic converter assembly configured to convert pollutants in an exhaust gas stream received from the exhaust manifold. The air compressor is configured to be fluidly coupled to the intake manifold of the engine for directing at least a first portion of the compressed air to the intake manifold of the engine. The air compressor is also selectively fluidly coupled to the catalytic converter assembly for selectively directing a second portion of the compressed air into the exhaust gas stream at a secondary air injection location at or upstream of the catalytic converter assembly.

Abstract: An exhaust system for a marine exhaust system includes two identical liquid-cooled exhaust manifolds. Each exhaust manifold has an outlet portion adapted to receive and retain a catalytic converter. Liquid cooled first and second risers are secured to the first and second exhaust manifolds. Bypass hoses enable fluid to pass from each exhaust manifold to its coupled riser. At the outlet of each riser, the cooling fluid and exhaust gas mix in a Y-pipe to create a combined flow. An exhaust outlet conduit downstream of the Y-pipe receives the combined flow and discharges the combined flow.

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.

Abstract: A heat exchange system for use on an engine-powered watercraft includes a liquid cooling system for cooling the engine using a first heat exchanger and a water heating system using a second heat exchanger for heating water. Raw water from an external water source is passed through each heat exchanger. Water used to cool the engine coolant inside the first heat exchanger exits the watercraft. Water heated by the second heat exchanger is passed to either an intake conduit or at least one onboard accessory system for flushing thereof to kill aquatic invasive species. A valve inside the second heat exchanger opens to release heated water when the heated water reaches a temperature of at least 140° F. Heated coolant from the first heat exchanger passes through the second heat exchanger to transfer heat to the water inside the second heat exchanger.

Abstract: A strainer assembly for a marine engine has a housing with an internal cavity. The housing has a threaded inlet end, an outlet and a flush port. A removable cover assembly covers the threaded inlet end and may be removed to allow a strainer to be removed from inside the housing and cleaned. The flush port may be closed with a plug and opened to allow a threaded end of a garden hose to be attached to the flush port for cleaning the engine.
