Designed specifically for commercial fishing boats and other marine vessels, this durable scupper features a recessed black internal flapper valve that prevents reverse water flow, keeping your boat dry and secure in all sea conditions.
Constructed with long threads, this marine drainage scupper passes easily through thicker transoms, providing versatile installation options across various boat builds. The hose barbs are engineered to fit standard 1-1/2" I.D. marine hoses, ensuring a tight, leak-proof connection with your boat’s plumbing system.
