Abstract
Contained within a splash water impervious housing and secured to a shock-mounted equipment support plate are an internal combustion engine, a water pump and a generator, each with a vertically-oriented shaft. Also disposed on the support plate immediately adjacent the engine's exhaust manifold is a water-cooled muffler. Combustion air for the engine and cooling air for the generator is drawn into the housing through a labyrinthian passage, which is effective to block the entry of splash water into the enclosure defined by the housing. The water pump and generator are driven by the engine with the water pump delivering cooling water to the engine's oil pan and cylinder block as well as to the muffler. The heated water is then discharged with the engine's exhaust through the muffler. Because of the cooling system employed, the engine, generator, water pump, muffler and the controls therefor can be compactly positioned relative to one another within the water-tight shroud, allowing the motor/generator set to be mounted exterior to the hull of the marine carft on its swim platform or, alternatively, in a bilge area where space is at a premium.
