The kit contains the fasteners needed to properly secure the motor mount during service or replacement, supplying a machined motor mount bolt along with its matching washer so the mount can be reassembled with the correct hardware rather than substituting mismatched bolts and washers from a hardware store bin. Each kit includes one 18-3729 Motor Mount Bolt and one 18-0681 Washer, giving installers a complete, matched set in a single part number.\u003c\/p\u003e\u003cp\u003eThis kit is designed for Mercruiser I engine applications and is built as a direct interchange for GLM 21811, so shops and owners who have sourced that reference number in the past can order the Sierra 18-2140 as an equivalent replacement. The hardware has a machined finish and is finished in white. Because the kit is compact and sold as a complete set, it simplifies ordering for engine mount service work where matching bolt and washer hardware is required.\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 18-2140\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Engine Mount Bolt Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Mercruiser I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e 1 Motor Mount Bolt (18-3729), 1 Washer (18-0681)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterchange Reference:\u003c\/strong\u003e GLM 21811\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.41 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercruiser I\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eGLM 21811\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2140 Engine Mount Bolt Kit include?\u003c\/strong\u003e The kit includes one 18-3729 Motor Mount Bolt and one 18-0681 Washer, providing the matched hardware needed to reinstall an engine mount in a single part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the 18-2140 fit?\u003c\/strong\u003e This bolt kit is designed for Mercruiser I engine applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2140 kit interchangeable with any other part number?\u003c\/strong\u003e Yes, the Sierra 18-2140 Engine Mount Bolt Kit is interchangeable with GLM 21811.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the engine mount bolt kit weigh?\u003c\/strong\u003e The Sierra 18-2140 Engine Mount Bolt Kit weighs 0.41 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-2140 kit?\u003c\/strong\u003e The kit measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the 18-2140 hardware have?\u003c\/strong\u003e The hardware in the 18-2140 kit has a machined finish and is colored white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many bolts come in one 18-2140 kit?\u003c\/strong\u003e One kit contains a single 18-3729 Motor Mount Bolt paired with one 18-0681 Washer, sold as one complete set per part number 18-2140.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part?\u003c\/strong\u003e Yes, part number 18-2140 is a genuine Sierra Engine Mount Bolt Kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need more than one 18-2140 kit for a full engine mount replacement?\u003c\/strong\u003e That depends on how many mounts are being serviced; each 18-2140 kit supplies one motor mount bolt and one washer, so the quantity needed scales with the number of mount positions being replaced.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the manufacturer part number for this engine mount bolt kit?\u003c\/strong\u003e The manufacturer part number is Sierra 18-2140.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988092498139,"sku":"SIE-18-2140","price":31.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2140_lg__53793.1558122354.500.750.jpg?v=1785187987","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2140-engine-mount-bolt-kit-for-mercruiser-i-replaces-10-97934-glm-21811-motor-mount-bolt-washer","provider":"Good Vibes Marina","version":"1.0","type":"link"}
