Abstract
An air supply system for a marine engine includes an air duct, or sound attenuator cavity, that receives air through a plurality of inlets and directs air to an outlet of the air duct disposed over a throttle body of an air intake manifold. An air filter assembly is shaped to be attached to a wall of the air duct with a filter medium portion extending into the cavity of the air duct and an outlet port or nipple, extending out of the air duct. A compressor is connected in fluid communication with the outlet port of the air filter assembly through the use of a flexible tube, such as a rubber hose, in order to provide filtered air to the compressor. The air filter assembly is easily removed for inspection and/or replacement and is located with its filter medium within the protective housing of the air duct.
