It regulates the charging voltage produced by the outboard's stator to keep the battery charging system operating within a safe range, protecting onboard electronics and the battery from damage caused by overcharging.\u003c\/p\u003e\u003cp\u003eThe regulator includes a built-in capacitor that provides high voltage spike protection, helping guard connected electrical components against transient voltage surges during engine operation. It is a compact, direct-fit unit designed to mount in place of the original Mercury\/Mariner regulator, and it cross-references directly to OEM part number 893640T01, so it installs using the existing mounting points and wiring connections on applicable EFI 4-Stroke outboards.\u003c\/p\u003e\u003cp\u003eSierra manufactures this regulator to serve as a reliable replacement for outboard owners and marine technicians who need to restore proper charging system function on Mercury\/Mariner 30, 40, 50, and 60 HP EFI 4-Stroke models.\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 18-5732-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Voltage Regulator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.64 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282398286\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeature:\u003c\/strong\u003e Built-in capacitor for high voltage spike protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Mercury\/Mariner 30\/40\/50\/60 EFI 4-Stroke\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury\/Mariner 30\/40\/50\/60 EFI 4-Stroke outboards\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e893640T01\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5732-1 voltage regulator fit?\u003c\/strong\u003e The Sierra 18-5732-1 voltage regulator fits Mercury\/Mariner 30\/40\/50\/60 EFI 4-Stroke outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5732-1 a direct replacement for the Mercury 893640T01 regulator?\u003c\/strong\u003e Yes, Sierra part 18-5732-1 replaces Mercury\/Mariner OEM voltage regulator 893640T01 and installs in the same location using the original mounting and wiring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this voltage regulator include surge protection?\u003c\/strong\u003e Yes, the Sierra 18-5732-1 has a built-in capacitor that provides high voltage spike protection for the outboard's electrical system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-5732-1 voltage regulator?\u003c\/strong\u003e It measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-5732-1 voltage regulator weigh?\u003c\/strong\u003e This voltage regulator weighs 0.64 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the function of a voltage regulator on an outboard motor?\u003c\/strong\u003e A voltage regulator like the Sierra 18-5732-1 controls the charging voltage sent from the stator to the battery, preventing overcharging and protecting the battery and onboard electronics.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-5732-1 work on any Mercury outboard?\u003c\/strong\u003e No, the Sierra 18-5732-1 is designed specifically for Mercury\/Mariner 30\/40\/50\/60 EFI 4-Stroke outboard models, not the full Mercury outboard lineup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-5732-1 an OEM or aftermarket part?\u003c\/strong\u003e The 18-5732-1 is a Sierra-manufactured aftermarket voltage regulator engineered to replace Mercury\/Mariner OEM part 893640T01.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-5732-1 come with mounting hardware?\u003c\/strong\u003e The dossier for the Sierra 18-5732-1 voltage regulator does not list included mounting hardware; it is sold as the regulator unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the Sierra 18-5732-1 cross-reference to?\u003c\/strong\u003e It cross-references to Mercury\/Mariner OEM part number 893640T01.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988229828827,"sku":"SIE-18-5732-1","price":156.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5732__54831.1558185449.500.750.jpg?v=1785188103","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5732-1-voltage-regulator-for-mercury-mariner-30-40-50-60-efi-4-stroke-outboards-replaces-893640t01","provider":"Good Vibes Marina","version":"1.0","type":"link"}
