The built-in magnet helps trap fine metal shavings that can otherwise recirculate through the lubrication system, giving a quick visual indicator of internal wear when the plug is removed for inspection. It is engineered to meet the demands of high horsepower marine engines and to hold up in the harsh marine environment, meeting or exceeding the performance of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003eThis drain screw directly replaces OEM numbers 688-45341-00-00 and 688-45341-10-00, and it is designed to be used together with Sierra gasket 18-4698 for a proper sealing surface at installation. Its compact size and standard M8-1.25 thread make it a straightforward swap during routine oil changes or gearcase service on applicable marine engines and drives.\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 18-2374\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e M8 - 1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Magnetic Drain Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompanion Gasket:\u003c\/strong\u003e Sierra 18-4698\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e Also available as 18-23741-9 (package of 50)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eFits applications using an M8-1.25 thread magnetic drain screw\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e688-45341-00-00\u003c\/li\u003e\n\u003cli\u003e688-45341-10-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does the Sierra 18-2374 magnetic drain screw use?\u003c\/strong\u003e The Sierra 18-2374 uses an M8 - 1.25 thread, so it is sized for drain openings that take that metric thread pitch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-2374 drain screw replace any OEM part numbers?\u003c\/strong\u003e Yes, it directly replaces OEM numbers 688-45341-00-00 and 688-45341-10-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2374 drain screw actually magnetic?\u003c\/strong\u003e Yes, it is a magnetic drain screw designed to attract and hold ferrous metal particles as fluid drains, helping you spot internal wear during oil changes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra 18-2374 made from?\u003c\/strong\u003e It is made from stainless steel, chosen for corrosion resistance in the marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need a gasket with the 18-2374 drain screw?\u003c\/strong\u003e Yes, Sierra 18-2374 is designed to be used with Sierra gasket 18-4698 to seal properly at the drain opening.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2374 drain screw weigh?\u003c\/strong\u003e The Sierra 18-2374 magnetic drain screw weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2374 available in bulk quantities?\u003c\/strong\u003e Yes, the same part is offered as 18-23741-9 in a package of 50 for shops that need multiple units.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the Sierra 18-2374 fit the same as the original equipment plug?\u003c\/strong\u003e It is engineered to meet or exceed the performance of the original equipment part it replaces, so it installs and seals the same way as the OEM plug it is designed to replace.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-2374 drain screw?\u003c\/strong\u003e The Sierra 18-2374 magnetic drain screw has a white finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a gasket included with the 18-2374 drain screw?\u003c\/strong\u003e No, the Sierra 18-2374 is the drain screw itself; the companion gasket, Sierra 18-4698, is a separate part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-2374 be used on both an engine and a gearcase?\u003c\/strong\u003e Any drain opening using an M8 - 1.25 thread magnetic drain screw, whether on the engine block or gearcase, can use the Sierra 18-2374.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988106031323,"sku":"SIE-18-2374","price":16.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2374_lg__58027.1558122591.500.750.jpg?v=1785188113","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2374-magnetic-drain-screw-m8-1-25-thread-replaces-yamaha-688-45341-00-00-outboard","provider":"Good Vibes Marina","version":"1.0","type":"link"}
