Stainless capped resin angled thru hull scupper 1 1/2" XL

Product Description

Upgrade your boat's drainage system with our high-performance 15-degree angled thru hull scupper, engineered for durability, style, and superior function. Crafted from tough fiberglass reinforced resin, this scupper is built to withstand the demanding saltwater environment while offering a lightweight alternative to full stainless steel fittings.

The polished 304 stainless steel cap, ultrasonically welded to the outer flange, not only adds a sleek, upscale look to your vessel but also offers enhanced resistance against sun and salt damage—common challenges with plastic thru hulls. Trusted by saltwater boat builders worldwide, this scupper combines reliability with marine-grade aesthetics.

Designed to fit transoms up to 3-5/8" thick, it features hose barbs compatible with standard 1-1/2" ID marine hoses, ensuring versatility for a variety of boat configurations. The included mounting nut makes installation quick and straightforward, saving you valuable time.

A recessed 1-5/8" diameter flapper ensures efficient drainage while preventing backflow into your boat, protecting your vessel from unwanted water intrusion. If you only need to replace the flapper, check out our convenient Scupper Flapper Kit 56677KT.
