It converts the alternating current produced by the outboard's stator into direct current to charge the battery and power onboard electronics, making it a core component of the engine's charging circuit. The housing has a machined exterior for a precise fit and reliable heat dissipation during operation. This rectifier is designed as a direct replacement for the original Mercury Marine unit, so it installs using the same 3 post mounting pattern without modification. Sierra manufactures this part to work in place of the OEM Mercury Marine rectifier and backs it with Sierra's industry leading customer satisfaction warranty, giving boat owners a dependable option for restoring their outboard's charging system. Compact and lightweight at just over two ounces on the water and rated in the specifications below, the 18-5707 is sized to fit within the same footprint as the original equipment part it replaces.\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 18-5707\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Rectifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 2 x 4 x 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePost Configuration:\u003c\/strong\u003e Square, 3 post rectifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999319524\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercury Outboard Voltage Regulators\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eAll outboard applications using a square, 3 post rectifier\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury Marine 62351A1\u003c\/li\u003e\n\u003cli\u003eMercury Marine 62351A2\u003c\/li\u003e\n\u003cli\u003eMercury Marine 816770T\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5707 rectifier fit?\u003c\/strong\u003e The Sierra 18-5707 fits outboard applications that use a square, 3 post rectifier configuration, and is designed as a direct replacement for the Mercury Marine rectifier it corresponds to.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich Mercury Marine part numbers does the 18-5707 replace?\u003c\/strong\u003e It replaces Mercury Marine 62351A1, 62351A2, and 816770T.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5707 an OEM part or an aftermarket replacement?\u003c\/strong\u003e The 18-5707 is a Sierra aftermarket rectifier manufactured to replace the equivalent Mercury Marine rectifier, not an OEM Mercury Marine part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-5707 rectifier weigh?\u003c\/strong\u003e The Sierra 18-5707 rectifier weighs 0.13 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-5707 rectifier?\u003c\/strong\u003e The product dimensions of the Sierra 18-5707 are 2 x 4 x 4 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the 18-5707 rectifier have?\u003c\/strong\u003e It has a machined exterior finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many mounting posts does the 18-5707 rectifier have?\u003c\/strong\u003e The 18-5707 is a square, 3 post rectifier.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-5707 come with a warranty?\u003c\/strong\u003e Yes, the Sierra 18-5707 rectifier is covered under Sierra's industry leading customer satisfaction warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the function of the 18-5707 rectifier in an outboard's charging system?\u003c\/strong\u003e The 18-5707 converts alternating current from the outboard's stator into direct current to charge the battery and run onboard electronics.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with the Sierra 18-5707?\u003c\/strong\u003e The Sierra 18-5707 rectifier carries UPC 030999319524.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988228124891,"sku":"SIE-18-5707","price":44.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5707_lg__51359.1558128710.500.750.jpg?v=1785188140","url":"https:\/\/www.goodvibesmarina.com\/products\/rectifier-for-mercury-outboard-replaces-62351a1-816770-square-3-post-sierra-18-5707","provider":"Good Vibes Marina","version":"1.0","type":"link"}
