The drive features a machined exterior finish in white and is built to Sierra's standard fit, form, and function specifications so it installs and operates the same as the original equipment part it replaces. As the engagement point between the starter motor and the flywheel, the drive assembly is a wear item that spins and retracts with each start cycle, so its threads, springs, and pinion gear teeth need to be in good condition for reliable cranking. This drive assembly directly replaces OEM part number 68575, making it a straightforward like-for-like swap when the original drive is worn, chipped, or no longer engaging smoothly. Sierra parts are backed by Sierra's customer satisfaction warranty, giving buyers confidence in fit and durability. Always confirm the 10 tooth pinion count and part number 18-5656 match your existing starter drive before ordering, since drive assemblies are built in different tooth counts for different starter applications and are not interchangeable across tooth counts.\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 18-5656\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Starter Drive Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTooth Count:\u003c\/strong\u003e 10 Tooth\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\u003eWeight:\u003c\/strong\u003e 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 747730044279\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 68575\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eSee the application chart for the specific engine models that use the 10 tooth 18-5656 drive assembly.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e68575\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5656 starter drive assembly do?\u003c\/strong\u003e It is the drive assembly that engages the starter motor with the engine flywheel ring gear, transmitting cranking torque to start the engine and then retracting once the engine fires.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many teeth does the 18-5656 drive have?\u003c\/strong\u003e The 18-5656 is a 10 tooth pinion drive assembly, and the tooth count must match your starter's original drive since tooth counts are not interchangeable between different starter applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-5656 replace?\u003c\/strong\u003e Part number 18-5656 replaces OEM number 68575, so it can be installed as a direct swap for that original drive assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-5656 drive assembly?\u003c\/strong\u003e The 18-5656 drive assembly has a white finish over its machined construction.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-5656 weigh?\u003c\/strong\u003e The Sierra 18-5656 starter drive assembly weighs 0.3 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-5656?\u003c\/strong\u003e Product dimensions for the 18-5656 are 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5656 an OEM or aftermarket part?\u003c\/strong\u003e The 18-5656 is a Sierra aftermarket replacement drive assembly designed to match the fit and function of the original 68575 drive it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if the 18-5656 fits my starter?\u003c\/strong\u003e Confirm both the part number 18-5656 and the 10 tooth pinion count against your existing starter drive assembly before ordering, since different starters use drives with different tooth counts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the finish on the 18-5656 drive?\u003c\/strong\u003e The 18-5656 has a machined exterior finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-5656 come with a warranty?\u003c\/strong\u003e Yes, the 18-5656 starter drive assembly is covered under Sierra's customer satisfaction warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with the 18-5656?\u003c\/strong\u003e The Sierra 18-5656 starter drive assembly carries UPC 747730044279.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988227043547,"sku":"SIE-18-5656","price":30.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5656_lg__25364.1558127840.500.750.jpg?v=1785188474","url":"https:\/\/www.goodvibesmarina.com\/products\/starter-drive-assembly-10-tooth-for-mercury-outboard-replaces-oem-68575-sierra-18-5656","provider":"Good Vibes Marina","version":"1.0","type":"link"}
