It seats and secures the bellows against the drive housing, maintaining a proper seal at the connection point between the bellows and the drive. As a direct replacement part, it is built to meet or exceed the specifications of the original equipment it replaces, making it a reliable choice when servicing or rebuilding the bellows assembly on a Bravo drive.\u003c\/p\u003e\u003cp\u003eThis flange ring is a small but essential component in the bellows system, and using the correct ring helps ensure the bellows seats correctly and holds its seal, which is critical for keeping water out of the boat and exhaust gases properly routed. It is sold as an individual replacement ring for technicians and boat owners performing bellows maintenance or full bellows replacement on Bravo-equipped MerCruiser 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 18-1710\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Bellow Flange Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282295097\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e 862209, 86814\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eAll Bravo sterndrive models\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e862209\u003c\/li\u003e\n\u003cli\u003e86814\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-1710 Bellow Flange Ring fit?\u003c\/strong\u003e The 18-1710 flange ring fits all Bravo sterndrive models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-1710 replace?\u003c\/strong\u003e This flange ring replaces OEM part numbers 862209 and 86814.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-1710 a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e It is a genuine Sierra part, manufactured to meet or exceed the specifications of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the weight of the 18-1710 Bellow Flange Ring?\u003c\/strong\u003e The Sierra 18-1710 Bellow Flange Ring weighs 0.05 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Bellow Flange Ring?\u003c\/strong\u003e The 18-1710 measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the finish on the 18-1710 flange ring?\u003c\/strong\u003e The flange ring has a machined exterior finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need to replace the flange ring when replacing the bellows on a Bravo drive?\u003c\/strong\u003e Yes, the 18-1710 flange ring seats and seals the bellows against the drive housing, so it should be inspected and replaced along with the bellows to maintain a proper seal on Bravo units.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-1710 fit an Alpha One drive?\u003c\/strong\u003e No, the 18-1710 is designated for all Bravo models; a separate flange ring, part number 18-1728, is used for Alpha One (GenII) applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-1710?\u003c\/strong\u003e The order includes one Sierra 18-1710 Bellow Flange Ring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-1710 come in a display package?\u003c\/strong\u003e The 18-1710 is the standard non-display packaged number; a corresponding display-packaged version exists as a separate item.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-1710 Bellow Flange Ring?\u003c\/strong\u003e The UPC for the Sierra 18-1710 Bellow Flange Ring is 808282295097.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988088860891,"sku":"SIE-18-1710","price":6.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-1710__86676.1729021691.500.750.jpg?v=1785189148","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-1710-bellow-flange-ring-for-mercruiser-bravo-replaces-oem-862209-86814","provider":"Good Vibes Marina","version":"1.0","type":"link"}
