It is built as a direct-fit replacement for the original equipment yoke and is designed to restore proper alignment and torque transfer between the engine and drive unit. This yoke fits All #1, R, MR, Alpha I, and Alpha I Gen II drives, as well as Bravo and Blackhawk drives, and it also fits Cobra sterndrives from 1986 and up. It is constructed of metal and finished in white, with compact dimensions of 0.39 x 0.39 x 0.39 inches, making it a small but critical connecting component in the drive train. The yoke is sold as a single piece and is intended as a like-for-like swap for the original part it replaces, meeting or exceeding the performance of the OEM component. Because this yoke crosses over multiple engine and drive brands, it is commonly used as a direct replacement for OEM and aftermarket yokes sold under GLM, Evinrude\/Johnson, Mallory, Mercruiser, OMC, and Volvo Penta part numbers. Confirm your drive model against the fitment list below before ordering to ensure correct compatibility.\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 18-2146\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Yoke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions (L x W x H):\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 4.43 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999752635\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAll #1, R, MR, Alpha I, Alpha I Gen II, Bravo \u0026amp; Blackhawk drives\u003c\/li\u003e\n\u003cli\u003eCobra drives, 1986 and up\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGLM 28315\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 912212\u003c\/li\u003e\n\u003cli\u003eMallory 9-72401\u003c\/li\u003e\n\u003cli\u003eMercruiser 59830A7\u003c\/li\u003e\n\u003cli\u003eMercruiser 59830A1\u003c\/li\u003e\n\u003cli\u003eOMC 912212\u003c\/li\u003e\n\u003cli\u003eOMC 3850815\u003c\/li\u003e\n\u003cli\u003eVolvo Penta 3850815\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat drives does the Sierra 18-2146 Yoke fit?\u003c\/strong\u003e This yoke fits All #1, R, MR, Alpha I, and Alpha I Gen II drives, as well as Bravo and Blackhawk drives, and it also fits Cobra drives from 1986 and up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2146 a genuine OEM part or an aftermarket replacement?\u003c\/strong\u003e The 18-2146 is a Sierra-manufactured replacement part designed to meet or exceed the performance of the original equipment yoke it replaces, rather than a part sourced from the original engine or drive manufacturer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the Sierra 18-2146 Yoke cross-reference to?\u003c\/strong\u003e It is interchangeable with GLM 28315, Evinrude\/Johnson 912212, Mallory 9-72401, Mercruiser 59830A7 and 59830A1, OMC 912212 and 3850815, and Volvo Penta 3850815.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-2146 Yoke made of?\u003c\/strong\u003e The Sierra 18-2146 Yoke is made of metal, finished in white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-2146 Yoke weigh?\u003c\/strong\u003e The Sierra 18-2146 Yoke weighs 4.43 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-2146 Yoke?\u003c\/strong\u003e The yoke measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-2146 Yoke come as a single piece?\u003c\/strong\u003e Yes, the Sierra 18-2146 Yoke is sold individually as one piece.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the Sierra 18-2146 fit a Cobra drive built before 1986?\u003c\/strong\u003e The 18-2146 Yoke is listed as a fit for Cobra drives from 1986 and up; fitment for earlier Cobra drives is not specified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Sierra 18-2146 Yoke be used on both Alpha One and Bravo drives?\u003c\/strong\u003e Yes, this same yoke, part number 18-2146, fits Alpha I, Alpha I Gen II, and Bravo drives, along with All #1, R, MR, and Blackhawk drives.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I identify the correct yoke for my Mercruiser drive?\u003c\/strong\u003e If your Mercruiser drive originally used part number 59830A7 or 59830A1, the Sierra 18-2146 Yoke is the correct cross-reference replacement.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988092858587,"sku":"SIE-18-2146","price":149.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2146_lg__68086.1558122774.500.750.jpg?v=1785188445","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2146-u-joint-shaft-coupler-yoke-replaces-mercury-59830a1-mercruiser-alpha-one-gen-ii-r-mr-bravo-blackhawk-omc-cobra","provider":"Good Vibes Marina","version":"1.0","type":"link"}
