Product Description:
Upgrade your boat’s drainage system with the SEAW1143, a premium marine-grade scupper designed as a direct replacement for the standard round plastic frame scuppers with rubber flappers. This high-performance scupper features a free-swinging rigid door ("flapper") combined with a hidden black marine-grade silicone seal, enabling faster drainage and superior one-way valve efficiency compared to traditional rubber flapper designs.
Crafted entirely from marine-grade 316 stainless steel, including all fasteners, the SEAW1143 offers unmatched corrosion resistance and durability in harsh marine environments. The 17-degree wedge design allows the scupper to “rest” in a closed position, accommodating most boat transoms angled between 10-15 degrees for optimal sealing and water flow control.
The scupper’s larger 1.625” thru-hole fits most brass drain tubes with a typical 1.5” flare, providing wider compatibility than many standard plastic scuppers with 1.375” openings. Installation is simplified with a wedge that can be mounted directly to the transom or a plastic thru-hull fitting, while the scupper itself attaches to the wedge using strong 3M VHB adhesive for a clean, screwless finish that enhances the aesthetics of your vessel.
