Replace your old worn-out flapper scupper with our new Flow-Max™ positive sealing ball scupper. Larger exit hole allows 70% more water drainage than its nearest competitor. Multiple mounting holes make retrofits quick and easy - no filling holes or re-drilling. Neutral buoyancy ball ensures ball won't float up and break seal. Meets all ABYC standards. New easy twist-off design makes cleaning debris a snap. Simply twist counterclockwise to remove ball cavity, clean out and twist back on. Stainless steel security pin provided for added safety. The Flow Max Scupper only comes with the one screw. The screws that screw it to the boat do not come with it. They will be different for every boat depending on the hull thickness but you will need a tapered head screw. Screw included is a #4 x 1/4" Phillips Pan Head Stainless Steel Screw.

Installation - scupper seal is slotted to fit over 1-1/4" motorwell tubes and includes a safety screw to keep valve in place - installation will require tapered head screws. Easy Cleaning - self-draining scupper features a new twist-off design that makes cleaning out excess debris a snap. Keep Your Cockpit and Deck Dry - boat scupper ball uses neutral buoyancy to ensure a tight seal and eliminate the possibility of water flowing back into the drainage lines.
