Instead of a hinged flapper that wears down and leaks over time, the Flow-Max design uses a neutral-buoyancy ball that seats securely in the scupper body, preventing the ball from floating up and breaking the seal. The larger exit hole moves up to 70% more water than competing flapper scuppers, which means faster self-bailing and a drier cockpit or deck.\u003c\/p\u003e\u003cp\u003eInstallation is built around convenience: the housing includes multiple mounting holes so it can retrofit common existing hole patterns without filling old holes or re-drilling new ones. The seal is slotted to fit over 1-1\/4 inch motorwell tubes. A stainless steel security pin is provided for added safety, and the unit ships with one #4 x 1\/4 inch Phillips pan head stainless steel screw; the additional screws used to fasten the scupper to the hull are not included, since the correct screw length depends on each boat's hull thickness, so a tapered-head screw sized to your hull is required. For maintenance, the ball cavity twists off counterclockwise for quick access, allowing debris to be cleared out in seconds before twisting the unit back into place. The Flow-Max Ball Scupper is molded in clear plastic and meets ABYC standards.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e T-H Marine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e FMS-1-0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Flow-Max Ball Scupper - Clear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Clear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 3 inch diameter x 2-1\/2 inch height\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotorwell Tube Fit:\u003c\/strong\u003e 1-1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type:\u003c\/strong\u003e Ball Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrainage Performance:\u003c\/strong\u003e Up to 70% more drainage than competitive flapper-style scuppers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hardware Included:\u003c\/strong\u003e One #4 x 1\/4 inch Phillips Pan Head Stainless Steel Screw and one stainless steel security pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Compliance:\u003c\/strong\u003e Meets ABYC standards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 733572042610\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 3 x 4.75 x 8.75 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size motorwell tube does the FMS-1-0 Flow-Max Ball Scupper fit?\u003c\/strong\u003e The seal on the T-H Marine Flow-Max Ball Scupper is slotted to fit over 1-1\/4 inch motorwell tubes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Flow-Max Ball Scupper come with all the mounting screws I need?\u003c\/strong\u003e Only one #4 x 1\/4 inch Phillips pan head stainless steel screw is included with the FMS-1-0 scupper.
