This bushing supports the shift shaft as it passes through the housing, reducing wear, play, and binding at the pivot point so shift engagement stays smooth and precise. Over time the factory bushing wears from repeated shift-lever movement and exposure to marine conditions, which can introduce slop into the shift linkage; installing a fresh Sierra bushing restores tight, accurate shift feel.\u003c\/p\u003e\u003cp\u003eSierra manufactures the 18-2154 as a direct cross-reference to Mercury Marine part number 23-30617A2, so it installs in the same location using the same mounting relationship as the original equipment part. It is sold as a single bushing (one unit per package) and is sized to match the shift shaft housing bore it replaces.\u003c\/p\u003e\u003cp\u003eThis part is identified by UPC 030999311580 and falls within Sierra's Mercruiser Shift Cables product line, making it easy for boat owners and marine technicians to source the correct bushing when servicing shift shaft housings rather than replacing the entire housing assembly.\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 18-2154\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type:\u003c\/strong\u003e Shift Shaft Housing Bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Mercruiser Shift Cables\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999311580\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Mercury Marine 23-30617A2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eDesigned for use in Mercruiser shift shaft housing assemblies as a direct replacement for the original bushing.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury Marine 23-30617A2\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2154 Shift Shaft Housing Bushing fit?\u003c\/strong\u003e The Sierra 18-2154 is designed for Mercruiser shift shaft housing assemblies, replacing the bushing that supports the shift shaft where it passes through the housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2154 bushing a genuine OEM part or aftermarket?\u003c\/strong\u003e Sierra 18-2154 is an aftermarket replacement bushing manufactured to cross-reference directly with Mercury Marine 23-30617A2, so it is not a Mercury Marine branded part but is built to fit the same application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes 18-2154 replace Mercury Marine part 23-30617A2?\u003c\/strong\u003e Yes, Sierra 18-2154 is the direct cross-reference for Mercury Marine 23-30617A2, so it installs in the same shift shaft housing location as that original part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the shift shaft housing bushing weigh?\u003c\/strong\u003e The Sierra 18-2154 Shift Shaft Housing Bushing weighs 0.03 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many bushings come in one package of 18-2154?\u003c\/strong\u003e One Sierra 18-2154 Shift Shaft Housing Bushing is included per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is used to verify I am ordering the correct part?\u003c\/strong\u003e Sierra 18-2154 is identified by UPC 030999311580, which can be used to confirm you are ordering the correct shift shaft housing bushing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace the shift shaft housing bushing?\u003c\/strong\u003e A worn shift shaft housing bushing allows play or looseness in the shift shaft, which can cause imprecise or sloppy shift lever feel; replacing it with the Sierra 18-2154 restores a tighter fit at that pivot point.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I replace just the bushing instead of the entire shift shaft housing?\u003c\/strong\u003e Yes, the Sierra 18-2154 lets you replace only the worn bushing within the shift shaft housing assembly rather than sourcing the complete housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of Mercruiser parts does 18-2154 belong to?\u003c\/strong\u003e Sierra lists the 18-2154 Shift Shaft Housing Bushing within its Mercruiser Shift Cables product line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2154 easy to install?\u003c\/strong\u003e The 18-2154 is a single-piece bushing sized to the shift shaft housing bore, allowing it to be installed in place of the worn original bushing during routine shift linkage service.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988092661979,"sku":"SIE-18-2154","price":20.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2154_lg__46243.1558123098.500.750.jpg?v=1785188952","url":"https:\/\/www.goodvibesmarina.com\/products\/shift-shaft-housing-bushing-18-2154-replaces-mercury-23-30617a2-for-mercruiser-sterndrive","provider":"Good Vibes Marina","version":"1.0","type":"link"}
