ABSTRACT:
Apparatus for preventing exhaust gases emitted from an exhaust pipe outlet at a boat transom from soiling the boat surfaces. The apparatus includes a normally flaccid tube encircling the exhaust pipe outlet. The tube becomes rigid and extends rearwardly from the transom upon receiving exhaust gases from the exhaust pipe outlet. The tube, when rigid, discharges the exhaust gases far enough away from the transom to reduce contact of the gases with the boat surfaces. In one embodiment, the tube is clamped directly to the exhaust pipe outlet. In a second embodiment, the tube is clamped directly to the boat transom via a flange encircling the exhaust pipe outlet.
