It uses an acetal body, measures 2-7\/8 inches in diameter, and fits the Attwood 3875B thru-transom thru-hull connector.\u003c\/p\u003e\u003cp\u003eIt replaces the valve used with the 3881 thru-transom scupper and is intended for above-the-waterline installation only. In use, the flapper opens to let cockpit water drain overboard and closes back to help reduce water coming in through the outlet.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e2-7\/8 inch scupper valve sized for self-bailing cockpit drains\u003c\/li\u003e\n\u003cli\u003eFits the Attwood 3875B thru-transom thru-hull connector\u003c\/li\u003e\n\u003cli\u003eReplacement valve for the Attwood 3881 thru-transom scupper\u003c\/li\u003e\n\u003cli\u003eAcetal construction\u003c\/li\u003e\n\u003cli\u003eFlapper-style valve that opens for drainage and closes back at the outlet\u003c\/li\u003e\n\u003cli\u003eScrew holes are drilled during installation\u003c\/li\u003e\n\u003cli\u003eFor above-the-waterline installation only\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis valve is for transom drain setups built around the 3875B connector or older 3881 scupper assemblies. It is a direct match when the existing drain uses the same 2-7\/8 inch Attwood valve format.\u003c\/p\u003e\u003cp\u003eIt is a sensible replacement when the original scupper valve has become worn, no longer swings freely, or no longer closes cleanly at the cockpit drain outlet.\u003c\/p\u003e\u003ch6\u003eInstallation and use\u003c\/h6\u003e\u003cp\u003eInstallation requires drilling the screw holes for the valve. Because this part is used above the waterline, it belongs on self-bailing cockpit drains and similar transom drainage points, not on below-the-waterline thru-hull openings.\u003c\/p\u003e\u003cp\u003eThis suits boats that rely on gravity drainage from the cockpit, including many center consoles, fishing boats, and other layouts with self-bailing deck areas.\u003c\/p\u003e","brand":"Attwood Marine","offers":[{"title":"Default Title","offer_id":52023508500661,"sku":"QBP537119","price":12.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1329506_qbp537119.jpg?v=1780191835","url":"https:\/\/www.qualityboatparts.com\/products\/qbp537119","provider":"Quality Boat Parts","version":"1.0","type":"link"}
