It features an improved solenoid design for maximum reliability, with a stronger connection between the solenoid and commutator brushes and an increased battery stud length that makes wiring the unit easier during installation.\u003c\/p\u003e\u003cp\u003eThe housing has been upgraded to reduce water intrusion, with seals strategically placed throughout the unit to keep moisture out. A duckbill valve and relief cuts give any water that does find its way in a path to exit before it can cause corrosion, and a reinforced clutch gear spring helps extend the life of the drive mechanism. The starter runs on a 12 volt DC system and delivers 1.4 KW of cranking power. The housing is constructed of plastic with a painted surface finish. Each unit ships as a single, complete replacement starter ready to install.\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 18-55506\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercury Outboard Starter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 Volts (DC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage:\u003c\/strong\u003e 1.4 KW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCranking Phase Type:\u003c\/strong\u003e Cranking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Painted surface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 7.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-55506 starter fit?\u003c\/strong\u003e The Sierra 18-55506 is built for Mercury outboard engines and is designed as a 12 volt cranking starter for that application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-55506 a 12 volt starter?\u003c\/strong\u003e Yes, this starter runs on a 12 volt DC electrical system and delivers 1.4 KW of cranking power.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the housing material on the 18-55506 starter?\u003c\/strong\u003e The housing is made of plastic with a painted surface finish, part of an upgraded design intended to reduce water intrusion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-55506 starter weigh?\u003c\/strong\u003e The Sierra 18-55506 starter weighs 7.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-55506 include any features to prevent corrosion?\u003c\/strong\u003e It includes a duckbill valve and relief cuts that let any moisture that enters the housing exit before corrosion can set in, along with seals placed throughout the unit to reduce water intrusion in the first place.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat comes with the Sierra 18-55506 starter?\u003c\/strong\u003e Each order includes one complete Sierra 18-55506 outboard starter, ready to install as a single unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the solenoid design matter on this starter?\u003c\/strong\u003e The 18-55506 uses an improved solenoid design that provides a stronger connection between the solenoid and the commutator brushes for more reliable starts, along with a longer battery stud for easier wiring during installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-55506 an OEM or aftermarket starter?\u003c\/strong\u003e The 18-55506 is a Sierra-brand replacement starter built with upgraded features such as an improved planetary seal and a reinforced clutch gear spring to extend service life.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of clutch gear does the 18-55506 use?\u003c\/strong\u003e This starter uses a clutch gear with a reinforced spring designed to maximize drive mechanism life span and reliability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Sierra 18-55506 be used in saltwater conditions?\u003c\/strong\u003e It is engineered for harsh marine environments, with sealing and a moisture relief valve intended to reduce corrosion from water intrusion, making it suited to marine outboard use.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988218360027,"sku":"SIE-18-55506","price":211.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/GFC__13130.1753840746.500.750.jpg?v=1785188942","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-55506-outboard-starter-for-mercury-outboards-12v-marine-starter-motor-with-upgraded-solenoid","provider":"Good Vibes Marina","version":"1.0","type":"link"}
