ABSTRACT:
An exhaust knockdown spray includes a scoop on the underside of a boat hull which picks up water when the boat is underway, and, through a conduit, directs the water to a spray nozzle at the rear of the hull where the water falls upon any exhaust coming out of the hull. The scoop is positioned ahead of the rudder blade so that the rudder has a steering effect after the steering effect of the scoop.
