ABSTRACT:
A flow conditioning member is attached to a distal end, or lip, of an air conduit within a space formed by inner and outer walls of a cowl for an outboard motor. The flow conditioning member is shaped to decrease the likelihood that a thickened boundary layer will form within the conduit as air flows from an air passage formed through the cowl to an air intake system of an internal combustion engine. The flow conditioning member is shaped to block the passage of water from the air passage to the air conduit while improving the efficiency of air flow from the air passage, into a space between the inner and outer walls, and into the air conduit.
