This solid cast 316 Stainless Steel thru hull scupper has an internal flapper to keep water from back-flowing and a highly polished flange that makes your boat look great! The long threads allow it to pass through thicker transoms and the hose barbs fit 1-1/2" I.D marine hose. 316 stainless mounting nut included.
These SS boat scuppers are the original equipment fittings used on many offshore saltwater fishing boats! This is the best replacement for the plastic scuppers on Yamaha jt boats!
