It is designated for use with Extreme Cables only, making it a specific replacement component rather than a universal fit for every shift cable setup. This screw plays a role in the shift slide assembly, where correct fit and secure engagement are essential for reliable gear selection and smooth shift operation. Given its small size and precise dimensions of 0.39 x 0.39 x 0.39 inches, it is manufactured to close tolerances so it seats properly within the shift slide hardware it is designed for. At 0.04 pounds, it is a lightweight hardware item intended to be installed as part of a shift cable or shift slide service, repair, or rebuild rather than sold as a standalone visible component. Because shift linkage hardware directly affects whether a drive shifts cleanly between gears, using the correct screw for an Extreme Cables application helps avoid improper engagement or premature wear at the shift slide interface. This part is identified under the Sierra brand and is cross-referenced to equivalent industry part numbers, helping buyers confirm they are ordering the correct hardware for their Mercruiser I\/O shift system repair.\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 18-2163\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Shift Slide Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e For Extreme Cables Only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive System:\u003c\/strong\u003e I\/O - Mercruiser Drive System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 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\u003eUPC:\u003c\/strong\u003e 808282257736\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGLM Cross Reference:\u003c\/strong\u003e 21090\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMallory Cross Reference:\u003c\/strong\u003e 9-72152\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercruiser I\/O Drive System, for Extreme Cables Only\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e10-31700\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-2163 Shift Slide Screw used for?\u003c\/strong\u003e The Sierra 18-2163 is a shift slide screw used in the shift mechanism of Mercruiser I\/O drive systems, specifically for applications using Extreme Cables.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-2163 shift slide screw fit any Mercruiser shift cable setup?\u003c\/strong\u003e No, the 18-2163 is designated for Extreme Cables only, so it should not be assumed to fit standard or other cable types used on Mercruiser I\/O drive systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-2163 shift slide screw?\u003c\/strong\u003e The 18-2163 measures 0.39 x 0.39 x 0.39 inches, reflecting its small size as a precision shift mechanism fastener.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-2163 shift slide screw weigh?\u003c\/strong\u003e This screw weighs 0.04 pounds, consistent with its role as a small hardware component rather than a full assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2163 equivalent to an OEM part number?\u003c\/strong\u003e Yes, the 18-2163 cross-references to OEM part number 10-31700 for buyers matching against original equipment numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre there other brand cross-reference numbers for the Sierra 18-2163?\u003c\/strong\u003e Yes, the 18-2163 cross-references to GLM number 21090 and Mallory number 9-72152.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra Shift Slide Screw 18-2163 genuine Sierra or aftermarket?\u003c\/strong\u003e The 18-2163 is a Sierra-branded part manufactured as a replacement component for Mercruiser I\/O drive system shift hardware.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat drive system does the 18-2163 shift slide screw belong to?\u003c\/strong\u003e It is used within the I\/O (inboard\/outboard) Mercruiser drive system, specifically within the shift slide hardware for Extreme Cables.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra 18-2163 shift slide screw made from?\u003c\/strong\u003e The sources for the 18-2163 do not specify a material for this screw.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if I need the 18-2163 versus a different shift slide screw?\u003c\/strong\u003e The 18-2163 is specifically for Extreme Cables applications on Mercruiser I\/O drive systems, so confirming your cable type before ordering ensures the correct fit.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988105081051,"sku":"SIE-18-2163","price":1.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2163_lg__66469.1558123720.500.750.jpg?v=1785188291","url":"https:\/\/www.goodvibesmarina.com\/products\/shift-slide-screw-for-mercruiser-i-o-drives-replaces-oem-10-31700-package-of-5-sierra-18-2163","provider":"Good Vibes Marina","version":"1.0","type":"link"}
