Its primary use is sealing the cylinder head to the engine block, maintaining compression and preventing leaks between the combustion chamber and the cooling passages. This gasket is finished in white and is supplied as a single unit, making it a straightforward, direct-fit replacement for a worn or damaged factory gasket during a head gasket service or top-end rebuild.\u003c\/p\u003e\u003cp\u003eThis part is designed for Chrysler\/Force 40 HP outboards covering model year 1992C and 1992-99 with serial number E000001 and up, as well as 50 HP outboards covering model years 1990A, 1989-92, B, C, D, and Z. It is interchangeable with Chrysler part number 27-F691529-1 and Mallory part number 9-63805, so it can be used as a direct cross-reference replacement for either of those numbers. At 0.08 pounds, it is a lightweight, low-profile gasket sized specifically for these outboard applications.\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 18-3853\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Outboard Head Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 (sold individually)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 707390466071\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e Chrysler 27-F691529-1, Mallory 9-63805\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eChrysler\/Force 40 HP outboards, model year 1992C and 1992-99, serial number E000001 and up\u003c\/li\u003e\n\u003cli\u003eChrysler\/Force 50 HP outboards, model years 1990A, 1989-92, B, C, D, Z\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eChrysler 27-F691529-1\u003c\/li\u003e\n\u003cli\u003eMallory 9-63805\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-3853 head gasket fit?\u003c\/strong\u003e This gasket fits Chrysler\/Force 40 HP outboards from model year 1992C and 1992-99 with serial number E000001 and up, and 50 HP outboards from model years 1990A, 1989-92, B, C, D, and Z.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-3853 head gasket the same as the Chrysler 27-F691529-1 gasket?\u003c\/strong\u003e Yes, Sierra 18-3853 is interchangeable with Chrysler part number 27-F691529-1, so it can be installed as a direct replacement for that OEM number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this gasket cross-reference to a Mallory part number?\u003c\/strong\u003e Yes, the 18-3853 head gasket is also interchangeable with Mallory part number 9-63805.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3853 head gasket weigh?\u003c\/strong\u003e It weighs 0.08 pounds, consistent with a single-layer gasket sized for a small outboard cylinder head.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-3853 head gasket?\u003c\/strong\u003e It is finished in white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in the package?\u003c\/strong\u003e The 18-3853 is sold as a single head gasket, one unit per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3853 an OEM or aftermarket part?\u003c\/strong\u003e It is an aftermarket Sierra replacement part built to meet or exceed the quality of the original Chrysler\/Force equipment it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-3853 head gasket work on a 1985 50 HP Chrysler outboard?\u003c\/strong\u003e The 18-3853 covers 50 HP model years 1990A and 1989-92, B, C, D, Z; earlier 50 HP model years use a different Sierra part number, so check your engine's model year and serial number before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-3853 be used on a 90 HP Chrysler\/Force outboard?\u003c\/strong\u003e No, the 18-3853 is designated for 40 HP and 50 HP Chrysler\/Force outboards only; other horsepower ratings use different Sierra head gasket part numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-3853?\u003c\/strong\u003e Each order includes one Sierra 18-3853 head gasket, ready to install between the cylinder head and engine block.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988168257755,"sku":"SIE-18-3853","price":35.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3853_lg__31072.1675867458.500.750.jpg?v=1785188172","url":"https:\/\/www.goodvibesmarina.com\/products\/head-gasket-for-chrysler-force-45-50-hp-outboard-replaces-oem-27-f691529-1-sierra-18-3853","provider":"Good Vibes Marina","version":"1.0","type":"link"}
