It is used to seal the gear lube fill or vent opening on lower units and gearcases, allowing technicians and boat owners to service gear lube without leaving the port open to water intrusion or debris. The plug is available in brass or stainless steel construction, both materials chosen for their resistance to corrosion in saltwater and freshwater marine environments.\u003c\/p\u003e\u003cp\u003eThis drain plug is sized to fit MerCruiser I, R, MR, Alpha One, TR, and TRS sterndrive units, as well as all outboards that use a 3\/8-16 non-magnetic gear lube fill or vent screw. It ships as a single plug (package quantity of 1), making it a straightforward replacement when an existing fill or vent screw is stripped, corroded, or missing. At 0.03 pounds, it is a small, lightweight hardware component intended to be kept on hand as spare gearcase service hardware.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-2244\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Drain Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 3\/8-16 inch (9.5mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Multi-coloured\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 747730043487\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMerCruiser I, R, MR, Alpha One, TR, TRS\u003c\/li\u003e\n\u003cli\u003eAll outboards with 3\/8-16 non-magnetic gear lube fill or vent screws\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the thread size of the Sierra 18-2244 drain plug?\u003c\/strong\u003e It uses a 3\/8-16 inch (9.5mm) thread, matching standard gear lube fill and vent screw ports on covered MerCruiser and outboard lower units.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-2244 fit my MerCruiser sterndrive?\u003c\/strong\u003e Sierra 18-2244 fits MerCruiser I, R, MR, Alpha One, TR, and TRS drive units.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this plug work on outboard motors?\u003c\/strong\u003e Yes, the 18-2244 fits all outboards that use a 3\/8-16 non-magnetic gear lube fill or vent screw.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this part made of?\u003c\/strong\u003e The Sierra 18-2244 drain plug is constructed from brass or stainless steel, both corrosion-resistant materials suited to marine gearcase service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many plugs come in a package?\u003c\/strong\u003e The 18-2244 is sold with a package quantity of 1 item.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2244 weigh?\u003c\/strong\u003e It weighs 0.03 pounds, a small, lightweight gearcase hardware component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2244 magnetic?\u003c\/strong\u003e No, it is designed as a non-magnetic gear lube fill or vent screw, per its stated fitment for non-magnetic ports.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this plug used for?\u003c\/strong\u003e The Sierra 18-2244 seals a gear lube fill or vent opening on a lower unit or gearcase during gear lube service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2244 an OEM or aftermarket part?\u003c\/strong\u003e The 18-2244 is a Sierra-branded replacement plug sized to fit the OEM 3\/8-16 gear lube fill and vent ports listed for MerCruiser and outboard applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use this plug on both the fill and vent ports?\u003c\/strong\u003e Yes, the 18-2244 is sized for 3\/8-16 non-magnetic gear lube fill or vent screw locations.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988106457307,"sku":"SIE-18-2244","price":3.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-2244__35690.1722519114.500.750.jpg?v=1785188297","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2244-marine-drain-plug-with-gasket-3-8-16-thread-for-mercruiser-alpha-one-sterndrives-mercury-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
