Bypass gaskets like this one seal the bypass passage on the powerhead, helping maintain proper sealing between mating surfaces during engine operation. Each pack is lightweight at just 0.01 pounds, reflecting its role as a precision-cut sealing component rather than a bulky assembly. Ordering the correct Sierra part number ensures the gasket matches the dimensions and bolt pattern of the original equipment it is designed to seal, which is important for preventing leaks and maintaining compression or fluid pathways within the powerhead. Because it ships two to a pack, boat owners and marine technicians can complete a full gasket replacement or keep a spare on the shelf without ordering twice. This gasket is cataloged under Sierra's Force Outboard Powerhead Gaskets line, making it easy to identify alongside other powerhead sealing components for the same engine family.\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 18-0141-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Force Outboard Powerhead Gaskets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 2 gaskets per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282161408\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in a Sierra 18-0141-9 pack?\u003c\/strong\u003e Two bypass gaskets ship in every pack of Sierra part number 18-0141-9, so a spare is included with each order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-0141-9 used for?\u003c\/strong\u003e It is a bypass gasket for the powerhead of Force outboard engines, used to seal the bypass passage during engine operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-0141-9 bypass gasket weigh?\u003c\/strong\u003e 0.01 pounds per pack, reflecting its size as a thin, precision-cut sealing gasket rather than a bulky part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category does this gasket fall under?\u003c\/strong\u003e Sierra catalogs the 18-0141-9 under its Force Outboard Powerhead Gaskets line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0141-9 sold individually or in a pack?\u003c\/strong\u003e It is sold per 2-pack, not as a single gasket, under Sierra part number 18-0141-9.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-0141-9 gasket?\u003c\/strong\u003e 808282161408 is the UPC associated with the Sierra 18-0141-9 bypass gasket 2-pack.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-0141-9 a genuine Sierra Marine part number?\u003c\/strong\u003e Yes, 18-0141-9 is the Sierra part number for this bypass gasket, identifying it within Sierra's Force outboard powerhead gasket lineup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShould I replace both gaskets at once when servicing the powerhead?\u003c\/strong\u003e Since the Sierra 18-0141-9 ships as a 2-pack, both gaskets are available in a single order, making it convenient to replace them together during a service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-0141-9 include installation hardware?\u003c\/strong\u003e The pack contains the bypass gaskets themselves (two per pack); no additional hardware is specified for this part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy order a spare Sierra 18-0141-9 gasket?\u003c\/strong\u003e Because bypass gaskets are used during powerhead service and can be damaged during removal, having the second gasket from the 2-pack on hand avoids a delay in completing the job.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988026732763,"sku":"SIE-18-0141-9","price":1.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0141_lg__13581.1558119741.500.750.jpg?v=1785329152","url":"https:\/\/www.goodvibesmarina.com\/products\/bypass-gasket-for-chrysler-force-outboard-100-140-hp-replaces-oem-27-f85762-2-pack-mpn-118-0141-9","provider":"Good Vibes Marina","version":"1.0","type":"link"}
