It is built to meet or exceed the quality of the original equipment part it replaces, making it a reliable choice for engine maintenance and water pump rebuilds. This gasket is supplied as a single unit and is intended for direct replacement of a specific set of Mercruiser gaskets, so it is commonly used when servicing or rebuilding a water pump assembly on compatible marine engines. Because a worn or damaged water pump gasket can allow coolant or raw water to leak past the pump housing, replacing it with a properly sized, OEM-quality gasket like the 18-0916 helps maintain a correct seal and proper cooling flow. Boat owners and marine technicians use this gasket when installing a new water pump, rebuilding an existing pump, or performing routine cooling system maintenance.\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 18-0916\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 747730043470\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e27-8052151\u003c\/li\u003e\n\u003cli\u003e27-805215\u003c\/li\u003e\n\u003cli\u003e27-94915\u003c\/li\u003e\n\u003cli\u003e27-72779\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-0916 used for?\u003c\/strong\u003e It is a water pump gasket used to seal the water pump housing on a marine engine, sealing out leaks between the pump body and the engine block or housing it mounts to.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-0916 gasket replace Mercruiser part numbers?\u003c\/strong\u003e Yes, the Sierra 18-0916 is a direct replacement for Mercruiser 27-8052151, 27-805215, 27-94915, and 27-72779.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in one order of the 18-0916?\u003c\/strong\u003e One Sierra 18-0916 Water Pump Gasket is included per unit, sold individually rather than as a multi-pack.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is the 18-0916 water pump gasket?\u003c\/strong\u003e The gasket has a round shape, matching the circular profile of the water pump housing it seals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-0916 weigh?\u003c\/strong\u003e This gasket weighs 0.02 pounds, consistent with a thin, lightweight sealing component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0916 an OEM part or an aftermarket replacement?\u003c\/strong\u003e The 18-0916 is a Sierra-manufactured replacement gasket engineered to meet or exceed the quality of the original Mercruiser gasket it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-0916 fit any water pump gasket application?\u003c\/strong\u003e It is intended specifically for applications that originally used Mercruiser 27-8052151, 27-805215, 27-94915, or 27-72779, so confirm your engine's original gasket number matches one of these before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with the Sierra 18-0916?\u003c\/strong\u003e The Sierra 18-0916 Water Pump Gasket carries UPC 747730043470.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-0916 be used when rebuilding a water pump?\u003c\/strong\u003e Yes, this gasket is commonly installed during a water pump rebuild or replacement to restore a proper seal at the pump housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-0916 water pump gasket made from?\u003c\/strong\u003e The specific gasket material is not specified for the Sierra 18-0916; buyers needing exact material composition should confirm with additional engine documentation.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988086272219,"sku":"SIE-18-0916","price":5.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0916_lg__94277.1558119254.500.750.jpg?v=1785188517","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0916-water-pump-gasket-replaces-mercruiser-27-805215-1-sterndrive-water-pump-base-gasket","provider":"Good Vibes Marina","version":"1.0","type":"link"}
