It is part of the charging circuit on the outboard, where it manages the electrical output from the stator so the motor's battery and onboard electronics receive properly regulated direct current at a safe, consistent amperage. A regulator\/rectifier of this type performs two jobs in one housing: it converts the alternating current generated by the outboard's stator into direct current, and it regulates that output so voltage stays within a safe range as engine RPM changes, protecting the battery and connected electrical components from overcharging.\u003c\/p\u003e\u003cp\u003eSierra produces this part as a replacement charging-system component for Johnson and Evinrude outboard applications, sized to handle a 35-amp charging load. It is cataloged under Sierra's Evinrude outboard rectifier regulator line and is built to the physical and electrical specifications needed for a direct fit in that charging system role. At 1.1 pounds, it is a compact, self-contained unit intended to mount within the outboard's electrical compartment.\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 18-99409\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Evinrude Outboard Rectifier Regulator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Johnson Evinrude outboard motors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 35 Amp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282394400\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJohnson outboard motors\u003c\/li\u003e\n\u003cli\u003eEvinrude outboard motors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-99409 used for?\u003c\/strong\u003e It is a voltage regulator\/rectifier for the charging system on Johnson and Evinrude outboard motors, converting the stator's AC output to regulated DC current.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat amperage does the Sierra 18-99409 regulator\/rectifier handle?\u003c\/strong\u003e The Sierra 18-99409 is rated for a 35-amp charging load.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich outboard brands is the Sierra 18-99409 designed for?\u003c\/strong\u003e It is built for Johnson and Evinrude outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWho manufactures part number 18-99409?\u003c\/strong\u003e Sierra manufactures this regulator\/rectifier under part number 18-99409.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-99409 weigh?\u003c\/strong\u003e This regulator\/rectifier weighs 1.1 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does a regulator\/rectifier like the Sierra 18-99409 actually do?\u003c\/strong\u003e It converts the alternating current produced by the outboard's stator into direct current and regulates the voltage so the battery and electrical system are not overcharged as engine RPM varies.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-99409?\u003c\/strong\u003e The UPC for this Sierra part is 808282394400.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category does the Sierra 18-99409 fall under?\u003c\/strong\u003e Sierra lists 18-99409 in its Evinrude outboard rectifier regulator category, covering charging-system components for Johnson and Evinrude outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99409 an OEM Johnson or Evinrude part?\u003c\/strong\u003e No, 18-99409 is a Sierra-branded replacement part made for Johnson and Evinrude outboard charging systems.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988442951899,"sku":"SIE-18-99409","price":354.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-193-4641_lg__02823.1558113028.500.750.jpg?v=1785329181","url":"https:\/\/www.goodvibesmarina.com\/products\/johnson-evinrude-35-amp-rectifier-regulator-for-outboards-sierra-18-99409","provider":"Good Vibes Marina","version":"1.0","type":"link"}
