This kit supplies the studs used to secure the flywheel coupler assembly, a connection point that must stay tight and properly torqued to transmit engine power to the drive unit without slipping or working loose under load. Sierra manufactures the kit to match the fit and thread engagement of the original coupler-to-flywheel hardware it is designed to replace, making it a straightforward drop-in for routine maintenance, coupler service, or flywheel replacement work.\u003c\/p\u003e\u003cp\u003eBecause this is a small, precision hardware kit, it ships compact and lightweight, and is intended to be installed with standard hand tools during coupler or flywheel service. Boat owners and marine technicians use it to restore the coupler-to-flywheel joint to proper specification rather than reusing worn or corroded studs.\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 18-72510\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Mercruiser Coupler to Flywheel\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\u003eWeight:\u003c\/strong\u003e 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282342746\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Engine Parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercruiser Coupler to Flywheel\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-72510 stud kit fit?\u003c\/strong\u003e The Sierra 18-72510 stud kit is designed to fit Mercruiser coupler-to-flywheel applications, supplying the hardware needed to secure that connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Sierra 18-72510 kit?\u003c\/strong\u003e This kit is a stud kit, meaning it supplies the studs used to attach the coupler to the flywheel on applicable Mercruiser setups.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-72510 stud kit weigh?\u003c\/strong\u003e The Sierra 18-72510 stud kit weighs 0.12 pounds, reflecting its compact size as a small hardware kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-72510 stud kit?\u003c\/strong\u003e The product measures 0.39 x 0.39 x 0.39 inches, consistent with a small, compact hardware kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-72510 stud kit genuine Sierra hardware?\u003c\/strong\u003e Yes, part number 18-72510 is manufactured and sold under the Sierra brand as a coupler-to-flywheel stud kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the 18-72510 stud kit have?\u003c\/strong\u003e The studs in this kit have a machined finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need to replace the coupler-to-flywheel studs?\u003c\/strong\u003e Studs like those in the Sierra 18-72510 kit typically need replacement during coupler or flywheel service, particularly if the existing hardware is worn, corroded, or has lost proper torque retention.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Sierra 18-72510 be installed with standard hand tools?\u003c\/strong\u003e Yes, this stud kit is intended for installation using standard hand tools during routine coupler or flywheel service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of part is the Sierra 18-72510?\u003c\/strong\u003e The 18-72510 is listed under Engine Parts as a stud kit for the coupler-to-flywheel connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-72510 kit fit all Mercruiser models?\u003c\/strong\u003e The Sierra 18-72510 stud kit is specified to fit Mercruiser coupler-to-flywheel applications; check that your unit uses this coupler-to-flywheel configuration before ordering.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988371419355,"sku":"SIE-18-72510","price":13.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-72510__46237.1722511592.500.750.jpg?v=1785188327","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-72510-stud-kit-for-mercruiser-coupler-to-flywheel-marine-engine-fastener-set","provider":"Good Vibes Marina","version":"1.0","type":"link"}
