Stainless Steel Thru Hull Scupper 2" Hose

Product Description:

Upgrade your boat’s drainage system with our Solid Cast 316 Stainless Steel Thru Hull Scupper, expertly engineered to provide unmatched durability, corrosion resistance, and reliable performance in harsh marine environments. Constructed from premium 316 stainless steel, this scupper features a sleek, highly polished flange that not only enhances your vessel’s aesthetics but also offers superior resistance to saltwater corrosion.

The built-in internal flapper prevents water back-flow, ensuring your boat remains dry even in rough offshore conditions. Designed with practical 1-7/8" threading, this thru hull scupper fits seamlessly through transoms and pairs perfectly with 2" I.D. marine hoses for efficient drainage.

Each scupper includes a heavy-duty 316 stainless steel mounting nut for secure and easy installation, making it a trusted choice for offshore saltwater fishing boats and other marine vessels. This product is frequently used as original equipment by top boat manufacturers, affirming its quality and marine-grade reliability.

To maintain optimal performance, replace worn flappers easily with our Flapper Replacement Kit (#PRE56555KT) — a cost-effective way to keep your scupper functioning perfectly without needing a full replacement.
