It manages the outboard's charging system by converting the alternating current produced by the stator into direct current and regulating output voltage to protect the battery and onboard electronics from overcharging. As a direct-fit electrical component, it is a straightforward swap for a failed or worn factory regulator\/rectifier, restoring reliable charging performance without rewiring the ignition or charging harness.\u003c\/p\u003e\u003cp\u003eThis unit is built to handle the 20-amp charging demand common to Johnson\/Evinrude outboard charging systems, making it suitable for boaters who need dependable voltage control to keep batteries properly charged during operation. It corresponds to CDI Electronics part number 193-4847, giving buyers a clear cross-reference point when searching for the correct replacement.\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 18-99436\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Voltage Regulator\/Rectifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 20 Amp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Johnson\/Evinrude Outboard Motors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282394677\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for Johnson and Evinrude outboard motors requiring a 20-amp voltage regulator\/rectifier.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eCDI Electronics 193-4847\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-99436 used for?\u003c\/strong\u003e It is a voltage regulator\/rectifier that converts the alternating current from a Johnson or Evinrude outboard's stator into direct current and regulates charging voltage to protect the battery and electronics.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat amperage does this regulator\/rectifier support?\u003c\/strong\u003e The Sierra 18-99436 is rated for 20 amps of charging output.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-99436 fit Johnson and Evinrude outboards?\u003c\/strong\u003e Yes, this regulator\/rectifier is built for Johnson and Evinrude outboard motors that use a 20-amp charging system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-99436 the same as CDI Electronics 193-4847?\u003c\/strong\u003e Sierra 18-99436 cross-references to CDI Electronics part number 193-4847, so either number identifies a compatible unit for the same application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this part weigh?\u003c\/strong\u003e The Sierra 18-99436 voltage regulator\/rectifier weighs 1 pound.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-99436?\u003c\/strong\u003e The UPC for this Johnson\/Evinrude voltage regulator\/rectifier is 808282394677.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this replace a failed factory voltage regulator?\u003c\/strong\u003e Yes, the Sierra 18-99436 is intended as a direct replacement for a worn or failed voltage regulator\/rectifier on compatible Johnson\/Evinrude outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat happens if a voltage regulator\/rectifier fails on an outboard?\u003c\/strong\u003e A failed regulator\/rectifier like the one the Sierra 18-99436 replaces can cause overcharging or undercharging of the battery, leading to battery damage or electrical system issues.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part?\u003c\/strong\u003e Yes, part number 18-99436 is a Sierra brand voltage regulator\/rectifier.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-99436 include mounting hardware?\u003c\/strong\u003e The listing covers the voltage regulator\/rectifier unit itself, identified by Sierra part number 18-99436.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988444098779,"sku":"SIE-18-99436","price":285.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-193-4847_lg__62936.1558113122.500.750.jpg?v=1785188050","url":"https:\/\/www.goodvibesmarina.com\/products\/johnson-evinrude-voltage-regulator-rectifier-20-amp-sierra-18-99436-outboard-rectifier","provider":"Good Vibes Marina","version":"1.0","type":"link"}
