Perko 0343DP Adjustable Thru-Hull Scupper for 1-1/2 Inch Hose, White

The Perko 0343DP is a transom mount thru-hull scupper designed for use with 1-1/2 inch hose. It is molded from durable white polymer and fitted with a recessed soft black flapper that opens to let water drain overboard while helping block backflow into the boat. The fitting body is designed with sections of ribs that can be cut out to adjust the fit for various surface thicknesses, allowing installation on transoms up to 2-1/8 inch thick. This makes the 0343DP a practical solution for routing bilge, livewell, or deck drain hose through the transom in a clean, finished way. Its recessed flapper design sits flush with the housing to reduce snagging and resist debris buildup compared to exposed-flap designs. A replacement flapper is available separately (Perko part number 0333DP099A) if the original flapper wears out or is damaged, letting boat owners refresh the scupper without replacing the entire fitting. With an inside diameter of 1-11/32 inch, a hole diameter of 1-13/16 inch, and a flange diameter of 2-15/16 inch, the 0343DP is sized to accept standard 1-1/2 inch hose while presenting a compact, low-profile flange on the transom face. It is built for through-hull hose drainage applications on boats where a molded white finish is preferred to blend with the hull.
