It is manufactured to meet or exceed the quality of the original equipment part it replaces, giving boat owners a direct, OEM-fit seal without the premium price of a dealer part.\u003c\/p\u003e\u003cp\u003eThis gasket is used as part of the mounting hardware for exhaust manifold elbow risers. In Sierra's mounting kit configuration, the 18-0897 elbow gasket is included alongside the 18-2849-1 elbow gasket for use with Manifold Spacer 18-1906 paired with Riser 18-1971 or Riser 18-1978, so it is a key seal when installing or servicing that manifold spacer and riser combination. Because it is sold individually here, it is also a convenient replacement-only purchase for anyone who already owns the elbows, spacer, and studs and simply needs a fresh, properly sized gasket to reseal the joint during a routine service or leak repair.\u003c\/p\u003e\u003cp\u003eEach gasket is a single round unit designed to be replaced any time the exhaust elbow or manifold spacer is removed, since a used gasket should not be reused once disturbed. It is interchangeable with several other aftermarket and OEM cross-reference part numbers, making it easy to source as a match for an existing Mercruiser exhaust system regardless of which brand originally supplied the gasket.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
