Quicksilver Gasket Exhaust Manifold to Elbow

The Mercury Quicksilver 27-8M0054712 Exhaust Manifold to Elbow Gasket is a genuine OEM replacement part manufactured by Mercury Marine. Designed to provide a precise, leak-free seal between the exhaust manifold and the exhaust elbow on MerCruiser 8.2L inboard and sterndrive engines, this gasket ensures reliable exhaust system performance and longevity. As a factory-original component, it meets all Mercury Marine specifications and tolerances—guaranteeing proper fitment without the guesswork associated with aftermarket alternatives.

This gasket is compatible with a broad range of 8.2L engine applications, including the 520 (0M970122 & Up), 540 (0M970866 & Up), 8.2L Inboard Base EC (2A041665 & Up), 8.2L Inboard H.O. EC (2A041665 & Up), 8.2L Mag Base Model (1A351597 & Up), 8.2L Mag H.O. Model (1A351597 & Up), and multiple 8.2L Mag EC variants. Replacing the exhaust elbow gasket at regular service intervals or whenever exhaust leaks are detected is essential to maintaining engine health and preventing water or exhaust gas intrusion into the engine bay.
