ABSTRACT:
A manifold and cooling system for V-type marine engines utilizing two novel exhaust manifold/cooling jacket units, each unit having separate cavities and a flow-through heat exchanger whereby engine coolant circulates through the engine block pumped by a water pump first into a forward cavity of one unit in fluidic communication with an exhaust manifold channel wall then traveling adjacent to the heat exchanger into a rearward cavity and into fluidic communication with a second portion of an exhaust manifold channel wall and then out of the unit via piping to a second unit into a rear cavity with similar fluidic communication with a second exhaust manifold channel wall then along a heat exchanger into a forward cavity and further channel wall contact, out of this unit and back into a engine block to complete the coolant circuit. Raw water is pumped (segregated from the coolant) through each heat exchanger and expelled back to the sea.
