{"product_id":"qbp776435","title":"Perko Garboard Drain Plug, 1 in NPT, Cast Bronze Flange, Steel Wrench","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Perko 0124000PLB is a garboard drain plug with a cast bronze flange, a brass plug, and a 1\/2 in x 1\/2 in square zinc-plated steel wrench. It is sized for a 1 in NPT drain opening, with a 1 in threaded neck, a 3-1\/8 in outside flange, and a mounting pattern that uses #10 screws.\u003c\/p\u003e\u003cp\u003eThis is the style of drain fitted on the outside surface of the hull for draining water when the boat is hauled or on the trailer. For a replacement job, the details that matter most are the 1 in NPT size, the 3-1\/8 in flange diameter, and the four-screw mounting layout, because those are the measurements that determine whether it drops into an existing installation without extra rework.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eCast bronze flange with brass plug\u003c\/li\u003e\n\u003cli\u003e1 in NPT pipe size with 1 in threaded neck\u003c\/li\u003e\n\u003cli\u003e3-1\/8 in outside flange diameter for checking footprint against the existing drain location\u003c\/li\u003e\n\u003cli\u003eOutside-surface mount that uses four #10 screws\u003c\/li\u003e\n\u003cli\u003e1\/2 in x 1\/2 in square zinc-plated steel wrench included for plug removal and installation\u003c\/li\u003e\n\u003cli\u003eSeparate service plug allows draining without removing the flange from the hull\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eCheck three points before ordering: the boat needs a 1 in NPT garboard drain, room for a 3-1\/8 in flange on the outside surface, and a four-hole pattern sized for #10 fasteners. On older hulls, matching the flange diameter and fastener layout can save time because it reduces the chance of redrilling or leaving old holes exposed.\u003c\/p\u003e\u003cp\u003eThis plug makes sense for owners replacing a worn bronze garboard drain on a trailer boat, skiff, runabout, or small cruiser that already uses this format. It also works well as a full replacement assembly when the existing plug or wrench is missing.\u003c\/p\u003e\u003ch6\u003eInstallation and use\u003c\/h6\u003e\u003cp\u003eThe included wrench engages the square recess in the plug, so routine draining and reinstallation are straightforward at haul-out, storage, or pre-launch service. In normal use, the flange stays fixed to the hull and the plug is the part you remove and reinstall as needed.\u003c\/p\u003e\u003cp\u003eBefore fitting a replacement, it is worth confirming the outside mounting surface is sound and that the existing opening matches the 1 in NPT thread size. That is usually the difference between a simple swap and a repair that turns into a larger hull job.\u003c\/p\u003e\u003ch6\u003eWhat's included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eGarboard drain plug assembly with cast bronze flange and brass plug\u003c\/li\u003e\n\u003cli\u003e1\/2 in x 1\/2 in square zinc-plated steel wrench\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Perko","offers":[{"title":"Default Title","offer_id":52023605919925,"sku":"QBP776435","price":160.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1330200_qbp776435.webp?v=1780191930","url":"https:\/\/www.qualityboatparts.com\/products\/qbp776435","provider":"Quality Boat Parts","version":"1.0","type":"link"}
