It is designed to restore a proper combustion seal between the cylinder head and engine block, preventing compression loss, coolant intrusion, and exhaust gas leakage that can result from a worn or failed factory gasket. Sierra builds this gasket to meet or exceed the specification of the original equipment part it replaces, using materials suited to withstand the heat cycling, pressure, and harsh marine environment outboard engines operate in. Each gasket is finished in white and sold as a package of 2, giving the installer the correct quantity on hand for a complete head gasket job without ordering twice. This part is intended for outboard engine rebuilds, head removal service, and repairs where the head gasket is being replaced as a matter of course due to age, overheating, or a failed seal. Because it carries the same cross-reference numbers as several original Chrysler\/Force part numbers, it is a straightforward swap for technicians and DIY boaters working from OEM parts diagrams or service manuals that list those numbers.\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 18-3857\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Head Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e Pack of 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Outboard - Chrysler\/Force\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower Range:\u003c\/strong\u003e 100 thru 140 H.P.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eChrysler\/Force outboard engines, 100 thru 140 H.P.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e27-824615\u003c\/li\u003e\n\u003cli\u003e27-824615-2\u003c\/li\u003e\n\u003cli\u003eF476529\u003c\/li\u003e\n\u003cli\u003eF476529-1\u003c\/li\u003e\n\u003cli\u003eF476529-2\u003c\/li\u003e\n\u003cli\u003e27-F476529-4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines is the Sierra 18-3857 head gasket designed for?\u003c\/strong\u003e The 18-3857 head gasket is built for Chrysler\/Force outboard engines rated 100 thru 140 H.P.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in a package?\u003c\/strong\u003e The 18-3857 is sold as a package of 2 head gaskets, enough for a single head gasket replacement job on most applications it covers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does this gasket replace?\u003c\/strong\u003e It replaces OEM numbers 27-824615, 27-824615-2, F476529, F476529-1, F476529-2, and 27-F476529-4.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine OEM gasket or an aftermarket part?\u003c\/strong\u003e The 18-3857 is a Sierra-manufactured aftermarket gasket built to meet or exceed the original equipment part it replaces, not a Chrysler\/Force branded OEM gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-3857 head gasket?\u003c\/strong\u003e This head gasket is finished in white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3857 head gasket weigh?\u003c\/strong\u003e The Sierra 18-3857 head gasket weighs 0.3 pounds per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this gasket fit a Force 125 HP outboard?\u003c\/strong\u003e Yes, the 18-3857 head gasket is designed for the 100 thru 140 H.P.
