Finished in white with a machined exterior, this small but critical part is engineered to meet or exceed original equipment quality, ensuring smooth and reliable shift engagement. It is designed as a direct interchange for a wide range of Mallory and Mercruiser OEM part numbers, making it easy to source a correct replacement when the original slide and screw show wear or damage. The compact dimensions and machined construction allow it to fit into the shift mechanism assembly exactly as the original part did, restoring proper shift feel and function without requiring modification to surrounding components. As with all Sierra parts, this shift slide and screw is manufactured to consistent quality standards so boat owners and marine technicians can install it with confidence that fit and performance will match or exceed the factory original.\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 18-2162\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Machined\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 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit Type:\u003c\/strong\u003e Universal Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282257729\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Mallory 9-72151; Mercruiser 8507522, 8507521, 33981T1, 33981T, 33981\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFit specific; verify against the OEM part numbers listed below to ensure correct fit for your MerCruiser shift mechanism.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMallory 9-72151\u003c\/li\u003e\n\u003cli\u003eMercruiser 8507522\u003c\/li\u003e\n\u003cli\u003eMercruiser 8507521\u003c\/li\u003e\n\u003cli\u003eMercruiser 33981T1\u003c\/li\u003e\n\u003cli\u003eMercruiser 33981T\u003c\/li\u003e\n\u003cli\u003eMercruiser 33981\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-2162 Shift Slide and Screw used for?\u003c\/strong\u003e The Sierra 18-2162 is a shift slide and screw component used within a MerCruiser stern drive shift mechanism to help transfer shift lever movement into gear engagement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-2162 replace Mercruiser part number 33981?\u003c\/strong\u003e Yes, the Sierra 18-2162 Shift Slide and Screw is designed to interchange with Mercruiser 33981, along with 33981T, 33981T1, 8507522, and 8507521.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2162 compatible with Mallory shift components?\u003c\/strong\u003e It is designed as a direct interchange for Mallory part number 9-72151, in addition to several Mercruiser OEM numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-2162 shift slide and screw?\u003c\/strong\u003e It is finished in white with a machined exterior surface.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-2162 weigh?\u003c\/strong\u003e The Sierra 18-2162 Shift Slide and Screw weighs 0.14 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of this part?\u003c\/strong\u003e The Sierra 18-2162 measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e The 18-2162 is a genuine Sierra-manufactured part, built to meet or exceed the quality of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-2162 fit any MerCruiser shift mechanism?\u003c\/strong\u003e Fit is part-number specific, so buyers should confirm their existing Mallory or Mercruiser part number matches one of the OEM cross-references for the 18-2162 before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-2162?\u003c\/strong\u003e The 18-2162 ships as the single shift slide and screw component, ready to install into the shift mechanism assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2162 still in production?\u003c\/strong\u003e Yes, the 18-2162 Shift Slide and Screw is not discontinued and remains available as a current Sierra part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the Sierra 18-2162 different from the original Mercruiser slide and screw?\u003c\/strong\u003e The Sierra 18-2162 is manufactured to the same fit and function as the original Mercruiser 33981\/8507522 series parts, so it installs as a drop-in equivalent.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988105015515,"sku":"SIE-18-2162","price":16.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-2162.2__51517.1729909513.500.750.jpg?v=1785187970","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2162-shift-slide-screw-for-mercruiser-sterndrive-shift-cable-replaces-33981t-8507522","provider":"Good Vibes Marina","version":"1.0","type":"link"}
