This assembly uses a.065 bore needle and seat, the precision-fit pairing that controls fuel flow into the carburetor bowl and is a common wear point that causes flooding, rough idle, or hard starting when it wears out or sticks. It is constructed from marine-grade material for durability in the fuel and moisture environment typical of outboard and personal watercraft carburetors.\u003c\/p\u003e\u003cp\u003eThis needle and seat is used as a rebuild component within Sierra carburetor kits WMK-2, WMK-3, WMK-4, WMK-5, WMK-7, and WMK-8, alongside companion part 18-7021, making it a key replacement item when servicing carburetors covered by those kits. It is intended for personal watercraft applications and is built to match the fit and function of the original Mercury Marine needle and seat 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 18-7061\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size:\u003c\/strong\u003e.065 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Needle \u0026amp; Seat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle Service Type:\u003c\/strong\u003e Personal Watercraft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999320957\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Mercury Marine 1395-8318\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUsed in Sierra carburetor rebuild kits WMK-2, WMK-3, WMK-4, WMK-5, WMK-7, and WMK-8 (paired with companion part 18-7021)\u003c\/li\u003e\n\u003cli\u003ePersonal watercraft applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury Marine 1395-8318\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7061 needle and seat assembly replace?\u003c\/strong\u003e It is a direct cross reference to Mercury Marine part number 1395-8318, so it fits applications that originally used that Mercury Marine needle and seat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat bore size is the 18-7061 needle and seat?\u003c\/strong\u003e This assembly uses a.065 inch bore, the size that controls fuel flow into the carburetor bowl.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat carburetor kits use part 18-7061?\u003c\/strong\u003e The 18-7061 needle and seat is used as a rebuild component in Sierra carburetor kits WMK-2, WMK-3, WMK-4, WMK-5, WMK-7, and WMK-8, alongside companion part 18-7021.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-7061 is a Sierra International part, manufactured as a direct replacement equivalent to the Mercury Marine 1395-8318 original.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with the 18-7061?\u003c\/strong\u003e The package includes one needle and seat assembly, matching the unit count and components of the original part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7061 needle and seat weigh?\u003c\/strong\u003e It weighs 0.01 pounds, consistent with a small precision carburetor component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the needle and seat made of?\u003c\/strong\u003e The 18-7061 assembly is constructed with marine-grade material for durability in fuel and moisture exposure typical of carburetor environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat vehicle types is the 18-7061 intended for?\u003c\/strong\u003e This needle and seat assembly is designated for personal watercraft applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if I need a new needle and seat?\u003c\/strong\u003e Symptoms like carburetor flooding, rough idle, or hard starting often point to a worn or stuck needle and seat, which the 18-7061 assembly is designed to correct when replaced.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the 18-7061 have?\u003c\/strong\u003e The assembly has a machined exterior finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7061 come with a warranty?\u003c\/strong\u003e Yes, the Sierra 18-7061 needle and seat is covered under Sierra's standard limited warranty.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988360835291,"sku":"SIE-18-7061","price":8.94,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7061_lg__95449.1558128806.500.750.jpg?v=1785188076","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-7061-marine-carburetor-needle-seat-replaces-mercury-1395-8318-065-bore-mercury-outboard","provider":"Good Vibes Marina","version":"1.0","type":"link"}
