The yoke connects the drive shaft to the u-joint coupler in the stern drive gimbal assembly, transmitting engine torque through the drive train. It is finished in black and constructed for reliable, repeated use in a marine environment where corrosion resistance and dimensional accuracy matter.\u003c\/p\u003e\u003cp\u003eThis yoke is sold as a single component (one yoke per package) and is intended as a replacement part when the original yoke shows wear, cracking, or play at the u-joint connection. Because it is manufactured to match the original Mercury Marine 46020T equivalent, it installs using the same fasteners and mating parts as the original part it replaces, without modification.\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 18-2125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Yoke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\/Finish:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions (L x W x H):\u003c\/strong\u003e 7.4 x 3.4 x 3.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999311436\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits applications that originally used Mercury Marine part number 46020T.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury Marine 46020T\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2125 yoke replace?\u003c\/strong\u003e It is a direct equivalent for Mercury Marine part number 46020T, so it installs anywhere that original part was used.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2125 an OEM Mercury Marine part or aftermarket?\u003c\/strong\u003e The 18-2125 is manufactured by Sierra as an aftermarket equivalent to the Mercury Marine 46020T yoke, not an original Mercury Marine part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-2125 yoke?\u003c\/strong\u003e It has a black finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-2125 weigh?\u003c\/strong\u003e This yoke weighs 2.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-2125 yoke?\u003c\/strong\u003e The item measures 7.4 x 3.4 x 3.3 inches (length x width x height).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many yokes come in the package?\u003c\/strong\u003e The 18-2125 is sold as a single yoke, one item per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat signals that a drive shaft yoke needs replacement?\u003c\/strong\u003e Cracking, wear, or excess play at the u-joint connection point on the existing yoke indicates it is time to replace it with a part like the Sierra 18-2125.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes installing the 18-2125 require modification to the drive shaft housing?\u003c\/strong\u003e No. Since the Sierra 18-2125 is built to match the Mercury Marine 46020T it replaces, it uses the same mounting points and mating parts without modification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2125 yoke?\u003c\/strong\u003e The UPC for the Sierra 18-2125 drive shaft yoke is 030999311436.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere does the yoke fit in the drive train?\u003c\/strong\u003e The 18-2125 yoke connects the drive shaft to the u-joint coupler in the gimbal assembly, transmitting torque from the engine through the drive shaft.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988092170459,"sku":"SIE-18-2125","price":81.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2125_lg__39226.1558121959.500.750.jpg?v=1785187970","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2125-yoke-assembly-short-replaces-mercury-46020t-for-mercruiser-alpha-one-gen-ii-i-o-drives","provider":"Good Vibes Marina","version":"1.0","type":"link"}
