This gasket seals the joint between the exhaust elbow and the exhaust manifold on compatible MerCruiser inboard and sterndrive engines, preventing exhaust gas and water leaks at one of the most heat-stressed sealing points in the engine’s cooling and exhaust system.\u003c\/p\u003e\u003cp\u003eSierra Marine produces these gaskets to OEM specifications for MerCruiser applications, ensuring correct material composition, thickness, and sealing surface dimensions for a reliable, long-lasting seal. Always replace the exhaust elbow gasket any time the elbow is removed — reusing a compressed gasket is a leading cause of exhaust leaks after service.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 18-0943-2 (Sierra Marine) | SKU: SIE-18-0943-2-9\u003c\/li\u003e\n\u003cli\u003eQuantity: 2 gaskets per pack\u003c\/li\u003e\n\u003cli\u003eSeals the exhaust elbow-to-manifold joint on compatible MerCruiser engines\u003c\/li\u003e\n\u003cli\u003eOEM-quality material and dimensions — direct fit replacement\u003c\/li\u003e\n\u003cli\u003eSingle-use — replace with a new gasket every time the elbow is removed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBest Use Case\u003c\/h3\u003e\u003cp\u003eBest suited for replacing the exhaust elbow gasket on compatible MerCruiser inboard and sterndrive engines during exhaust elbow removal, riser service, or manifold replacement. The 2-pack is ideal for twin-engine vessels or for keeping a spare on hand. Always inspect the exhaust elbow and manifold mating surfaces for corrosion or warping before reinstalling — a damaged sealing surface will cause leaks even with a new gasket. Confirm engine model and year against the Sierra application guide before ordering.\u003c\/p\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eExhaust elbow gaskets are a must-sell any time a customer purchases an exhaust elbow, riser, or manifold — they should never reuse the old gasket. The 2-pack is an easy upsell for twin-engine boats.
