It is a direct replacement for the shift shafts used in these drive units, restoring proper connection between the shift mechanism and the drive so gear engagement operates smoothly and reliably. The shaft is finished in white and machined from aluminum for corrosion resistance and long service life in a marine environment.\u003c\/p\u003e\u003cp\u003eEach package includes one shift shaft. Sierra states that this part meets or exceeds the original equipment part it replaces, making it a straightforward like-for-like swap for boat owners and marine technicians servicing Mercruiser I and Alpha I stern drive units. Because the shaft is specific to these drive models, confirming your drive type before ordering ensures correct fitment.\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 18-2322\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.34 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1 shift shaft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Mercruiser I and Alpha I stern drives\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 62104, 621041\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282257798\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercruiser I stern drive\u003c\/li\u003e\n\u003cli\u003eMercruiser Alpha I stern drive\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e62104\u003c\/li\u003e\n\u003cli\u003e621041\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2322 shift shaft fit?\u003c\/strong\u003e The 18-2322 shift shaft is built for Mercruiser I and Alpha I stern drives.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich OEM part numbers does the 18-2322 replace?\u003c\/strong\u003e It replaces Mercruiser 62104 and 621041.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the 18-2322 shift shaft made of?\u003c\/strong\u003e Aluminum, machined and finished in white, is the material used for the Sierra 18-2322 shift shaft.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2322 shift shaft weigh?\u003c\/strong\u003e 0.34 pounds is the weight of the Sierra 18-2322 shift shaft.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many shift shafts are included when I order the 18-2322?\u003c\/strong\u003e One shift shaft per package is included with the Sierra 18-2322.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2322 a genuine Mercruiser part or an aftermarket replacement?\u003c\/strong\u003e It is an aftermarket replacement; Sierra states the 18-2322 meets or exceeds the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-2322 shift shaft work on Mercruiser drives other than I and Alpha I?\u003c\/strong\u003e No, the 18-2322 is designated for Mercruiser I and Alpha I stern drives only, so it should not be assumed to fit other drive models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-2322 shift shaft carry a warranty?\u003c\/strong\u003e Yes, the Sierra 18-2322 shift shaft is covered by a limited warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2322 the same shaft as Mercruiser 62104 or 621041?\u003c\/strong\u003e Functionally yes, the Sierra 18-2322 is designed to replace both Mercruiser 62104 and 621041 shift shafts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-2322 shift shaft?\u003c\/strong\u003e White is the finish color of the Sierra 18-2322 shift shaft.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988105801947,"sku":"SIE-18-2322","price":59.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-2322__83053.1722500578.500.750.jpg?v=1785188048","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2322-shift-shaft-for-mercruiser-i-alpha-i-stern-drives-replaces-62104","provider":"Good Vibes Marina","version":"1.0","type":"link"}
