It functions as the high-current switch that engages the starter motor when the ignition key is turned, carrying the heavy load from the battery to the starter while isolating that current from the low-amperage ignition circuit. This solenoid is designed to pair with specific Mercruiser starter assemblies, including starter numbers 1108755, 1109484, 1109485, and 1109486 used on 1977-82 12 volt applications, as well as 12 volt starters used across 1971-78 applications.\u003c\/p\u003e\u003cp\u003eBuilt to withstand the vibration, heat, and moisture exposure typical of a marine engine compartment, the 18-5838 is a straightforward bolt-on replacement for a worn or failed OEM solenoid, restoring reliable starter engagement without requiring a full starter rebuild. It is sold as a single unit ready to install in place of the original switch.\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 18-5838\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Starter Solenoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 Volt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Mercruiser Stern Drive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Starter Model Numbers:\u003c\/strong\u003e 1108755, 1109484, 1109485, 1109486 (1977-82); ALL 12 volt starters (1971-78)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage:\u003c\/strong\u003e 1.2 kilowatts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase Type:\u003c\/strong\u003e Single Phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 7 x 3.5 x 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.18 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999320063\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Limited Warranty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Delco 1114356, Delco 1114458, Mercury Marine 33261, Mercury Marine 89902\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercruiser stern drive starters, starter numbers 1108755, 1109484, 1109485, 1109486, 12 volt, 1977-82\u003c\/li\u003e\n\u003cli\u003eMercruiser stern drive starters, 12 volt, all starter numbers, 1971-78\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDelco 1114356\u003c\/li\u003e\n\u003cli\u003eDelco 1114458\u003c\/li\u003e\n\u003cli\u003eMercury Marine 33261\u003c\/li\u003e\n\u003cli\u003eMercury Marine 89902\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5838 solenoid do?\u003c\/strong\u003e The Sierra 18-5838 is a 12 volt starter solenoid that switches high-amperage battery current to the starter motor when the ignition key is turned, letting a low-current ignition circuit control a heavy-duty starting load on Mercruiser stern drive engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-5838 fit my Mercruiser starter?\u003c\/strong\u003e It is designed for Mercruiser stern drive starters with starter numbers 1108755, 1109484, 1109485, or 1109486 on 12 volt, 1977-82 applications, and for 12 volt Mercruiser starters (all starter numbers) on 1971-78 applications.
