It is sold as a package of 5 O-rings, giving boat owners and technicians enough units on hand to complete a full gearcase service or to keep spares available for future maintenance without needing to reorder right away.\u003c\/p\u003e\u003cp\u003eO-rings like the 18-7133-9 are used to create a tight seal at gearcase and drive component joints, helping prevent water intrusion and lubricant leaks that can lead to internal corrosion or gear damage if left unaddressed. Replacing worn or hardened O-rings during routine gearcase service is a standard maintenance step for outboard drive systems, and having a multi-pack on hand makes it easier to replace every seal in a service rather than reusing an old one that may no longer hold a proper seal.\u003c\/p\u003e\u003cp\u003eThis part is identified by Sierra part number 18-7133-9 and is categorized for Evinrude outboard gearcase and drive parts, making it a straightforward choice when servicing compatible Evinrude lower unit and drive components.\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 18-7133-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 5 O-rings per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Evinrude Outboard Gearcase and Drive Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282165147\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis O-ring is designated for Evinrude outboard gearcase and drive applications.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-7133-9 O-ring used for?\u003c\/strong\u003e It is a sealing O-ring used in Evinrude outboard gearcase and drive service, helping maintain a watertight and lubricant-tight seal at gearcase and drive component joints.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many O-rings come in a package?\u003c\/strong\u003e The 18-7133-9 is sold in a package of 5 O-rings, enough for a full gearcase service or to keep spares on hand for future maintenance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-7133-9 fit all Evinrude outboards?\u003c\/strong\u003e This O-ring is categorized for Evinrude outboard gearcase and drive parts; specific model and gearcase compatibility should be confirmed against the gearcase or drive component being serviced.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7133-9 O-ring weigh?\u003c\/strong\u003e Each package of the Sierra 18-7133-9 O-rings weighs 0.06 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-7133-9 a genuine Sierra part?\u003c\/strong\u003e Yes, 18-7133-9 is a Sierra brand part number, sold as a replacement O-ring for Evinrude gearcase and drive applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShould I replace all the O-rings during a gearcase service?\u003c\/strong\u003e It is common practice to replace every O-ring during a gearcase or drive service rather than reuse old ones, which is why the Sierra 18-7133-9 is sold as a pack of 5.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy do gearcase O-rings need to be replaced?\u003c\/strong\u003e O-rings like the 18-7133-9 can harden or wear over time, and a failed seal can allow water intrusion or lubricant leaks that damage internal gearcase components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the part number for this O-ring?\u003c\/strong\u003e The part number is 18-7133-9, a Sierra brand replacement O-ring for Evinrude outboard gearcase and drive parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I buy a single 18-7133-9 O-ring instead of a pack?\u003c\/strong\u003e The 18-7133-9 is sold as a package of 5 O-rings, not as an individual unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of parts does the 18-7133-9 belong to?\u003c\/strong\u003e It falls under Evinrude Outboard Gearcase and Drive Parts, used specifically for sealing applications in that system.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988364275931,"sku":"SIE-18-7133-9","price":12.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7133-9__62908.1737885079.500.750.jpg?v=1785329171","url":"https:\/\/www.goodvibesmarina.com\/products\/outboard-water-pump-o-ring-replaces-oem-91301-zg3-000-sierra-18-7133-9-pack-of-5","provider":"Good Vibes Marina","version":"1.0","type":"link"}
