The kit is finished in white and includes the transom seal kit components needed for a proper seal at this critical connection point. Keeping the transom seal in good condition is essential to protecting the bilge from water entry and maintaining the integrity of the stern drive housing. This kit carries the Sierra brand name that boat owners and marine technicians rely on for stern drive and outboard replacement parts. At 4.6 pounds, it ships as a complete, ready-to-install kit under Sierra part number 18-8213.\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 18-8213\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Mercruiser Bellows\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Transom Seal Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 4.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282305277\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-8213 transom seal kit used for?\u003c\/strong\u003e It is a transom seal kit that seals the transom assembly on Mercruiser bellows systems, helping prevent water from entering the boat where the drive unit passes through the hull.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-8213 seal kit?\u003c\/strong\u003e The kit is white in color and round in shape.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-8213 transom seal kit weigh?\u003c\/strong\u003e This transom seal kit weighs 4.6 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-8213 a complete kit or a single part?\u003c\/strong\u003e Sierra part 18-8213 is sold as a transom seal kit, meaning it includes the components needed for the transom seal as a set rather than a single individual piece.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat brand makes part number 18-8213?\u003c\/strong\u003e Part number 18-8213 is manufactured by Sierra, a brand known for marine engine and stern drive replacement parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-8213 genuine Sierra or aftermarket?\u003c\/strong\u003e It is a genuine Sierra-branded transom seal kit, not a generic third-party part, carrying Sierra's own part number 18-8213.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of boat parts does the 18-8213 seal kit belong to?\u003c\/strong\u003e This Sierra seal kit falls under Mercruiser bellows related products, since transom seals work alongside the bellows system on stern drive boats.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-8213 transom seal kit?\u003c\/strong\u003e The UPC for this Sierra transom seal kit is 808282305277.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is the Sierra transom seal in kit 18-8213?\u003c\/strong\u003e The seal included in Sierra kit 18-8213 is round in shape.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy is replacing the transom seal important on a stern drive boat?\u003c\/strong\u003e A worn or damaged transom seal, such as the one included in Sierra kit 18-8213, can allow water to enter the bilge through the drive unit opening in the transom, so replacing it helps maintain a proper watertight seal.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988433023195,"sku":"SIE-18-8213","price":195.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/Untitled-1__32907.1753840720.500.750.jpg?v=1785189057","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-8213-transom-seal-kit-for-mercruiser-r-mr-alpha-one-1983-90-sterndrives-replaces-30-803097t1","provider":"Good Vibes Marina","version":"1.0","type":"link"}
