It is engineered to work with Volvo Penta, Mercruiser, and Marine Power engine platforms that share this flywheel and engine configuration, providing the high-current switching needed to engage the starter motor reliably in a marine environment.\u003c\/p\u003e\u003cp\u003eAs a starter solenoid, it acts as the electrical relay between the ignition switch and the starter motor, handling the heavy current draw required to crank the engine while allowing a low-current switch circuit to trigger it. This keeps the ignition switch and wiring protected from the high amperage the starter motor demands. Choosing a solenoid matched to your engine's flywheel size and engine family helps ensure correct fit and dependable starting performance.\u003c\/p\u003e\u003cp\u003eThe unit ships in package dimensions of 7.8 x 3.9 x 3.7 inches and weighs 1.73 pounds, consistent with a standard marine starter solenoid housing.\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 18-5811-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Starter Solenoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Volvo Penta, Mercruiser, Marine Power - Late Model 3.0L Engines with 14 inch Flywheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.73 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 7.8 x 3.9 x 3.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282378943\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eVolvo Penta, Mercruiser, and Marine Power late model 3.0L engines with a 14 inch flywheel\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-5811-1 solenoid fit?\u003c\/strong\u003e This solenoid is built for late model 3.0L engines with a 14 inch flywheel, covering Volvo Penta, Mercruiser, and Marine Power engine platforms that use this configuration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5811-1 a starter solenoid or an ignition solenoid?\u003c\/strong\u003e The 18-5811-1 is a starter solenoid, which switches the high-current circuit needed to engage the starter motor when the ignition is turned to start.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-5811-1 weigh?\u003c\/strong\u003e The Sierra 18-5811-1 solenoid weighs 1.73 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions for this solenoid?\u003c\/strong\u003e The Sierra 18-5811-1 ships in a package measuring 7.8 x 3.9 x 3.7 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-5811-1 work on any 3.0L marine engine?\u003c\/strong\u003e It is designed for late model 3.0L engines with a 14 inch flywheel, so confirm your engine has this flywheel size before ordering the 18-5811-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-5811-1 fit Volvo Penta engines specifically?\u003c\/strong\u003e Yes, Volvo Penta is one of the three engine platforms this solenoid is built to fit, alongside Mercruiser and Marine Power, on late model 3.0L engines with a 14 inch flywheel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5811-1 a genuine Sierra part?\u003c\/strong\u003e Yes, the 18-5811-1 is a Sierra branded starter solenoid, identified by Sierra part number 18-5811-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this solenoid?\u003c\/strong\u003e The UPC for the Sierra 18-5811-1 starter solenoid is 808282378943.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does a starter solenoid do on a marine engine?\u003c\/strong\u003e A starter solenoid like the 18-5811-1 relays high current from the battery to the starter motor when triggered by the ignition switch, allowing the engine to crank without routing full starter current through the ignition wiring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the flywheel size matter when choosing this solenoid?\u003c\/strong\u003e Yes, the Sierra 18-5811-1 is matched to engines with a 14 inch flywheel, so flywheel size is a key fitment factor for this part.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988323741915,"sku":"SIE-18-5811-1","price":49.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-5811-1__34035.1737892102.500.750.jpg?v=1785188048","url":"https:\/\/www.goodvibesmarina.com\/products\/starter-solenoid-for-mercury-mariner-verado-dfi-outboards-replaces-809463a1-fits-pg260-series-starters-sierra-18-5811-1","provider":"Good Vibes Marina","version":"1.0","type":"link"}
