As a direct replacement component, it restores proper connection between the battery and starter motor, addressing the common failure point where a worn or corroded solenoid prevents an outboard engine from cranking. The solenoid is built to the same fit and function as the original equipment it replaces, so it installs using the existing mounting points and wiring terminals without modification.\u003c\/p\u003e\u003cp\u003eThis solenoid is designed as a cross-reference match for OMC and Mercury Marine part numbers, making it a straightforward swap when the original unit fails or shows signs of pitting, sticking contacts, or intermittent starting. Keeping a correctly matched solenoid on hand helps avoid downtime caused by a no-crank condition, which is one of the most frequent electrical issues on outboard-powered boats.\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 18-5808\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Solenoid, Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.65 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Evinrude Outboard Starter Solenoids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eCross-referenced to OMC and Mercury Marine starter solenoid applications; confirm your existing part number against the replaces list below before ordering.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOMC 395419\u003c\/li\u003e\n\u003cli\u003eOMC 582708\u003c\/li\u003e\n\u003cli\u003eMercury 47886T\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5808 solenoid replace?\u003c\/strong\u003e It is cross-referenced to OMC 395419, OMC 582708, and Mercury Marine 47886T, so any of those original part numbers can be replaced with the Sierra 18-5808.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5808 an OEM or aftermarket solenoid?\u003c\/strong\u003e The 18-5808 is a Sierra-brand replacement solenoid built to match the fit and function of the OMC and Mercury Marine originals it cross-references, rather than being sourced from OMC or Mercury Marine directly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-5808 solenoid weigh?\u003c\/strong\u003e The Sierra 18-5808 solenoid weighs 0.65 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-5808 fit my Evinrude or OMC outboard?\u003c\/strong\u003e Yes, if your outboard's original solenoid carries one of the cross-referenced numbers OMC 395419 or OMC 582708, the Sierra 18-5808 is the matching replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this solenoid work as a Mercury Marine 47886T replacement?\u003c\/strong\u003e Yes, the Sierra 18-5808 cross-references directly to Mercury Marine part number 47886T.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order part 18-5808?\u003c\/strong\u003e Ordering 18-5808 gets you a single Sierra medium starter solenoid; no additional wiring or mounting hardware is included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy is my outboard failing to crank, and could the solenoid be the cause?\u003c\/strong\u003e A worn or corroded starter solenoid is a common cause of no-crank conditions on outboard engines, and replacing it with the Sierra 18-5808 is a standard first step when the starter itself tests good.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5808 solenoid described as 'medium' a different size than other Sierra solenoids?\u003c\/strong\u003e Yes, the 18-5808 is designated by Sierra as a medium solenoid, distinguishing it from other solenoid sizes in the Sierra lineup that use different part numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I cross-check the 18-5808 against my old solenoid's part number before ordering?\u003c\/strong\u003e Yes, check your old solenoid for OMC 395419, OMC 582708, or Mercury Marine 47886T; any of these confirms the Sierra 18-5808 is the correct replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of part is the Sierra 18-5808?\u003c\/strong\u003e The Sierra 18-5808 is listed under Evinrude Outboard Starter Solenoids.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988323545307,"sku":"SIE-18-5808","price":29.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5808_lg__99839.1558130119.500.750.jpg?v=1785188423","url":"https:\/\/www.goodvibesmarina.com\/products\/starter-solenoid-for-omc-johnson-evinrude-mercury-outboards-replaces-395419-582708-47886-sierra-18-5808","provider":"Good Vibes Marina","version":"1.0","type":"link"}
