Mercury Marine Exhaust Manifold Assembly Port
The Mercury Marine 8M0104214 port-side exhaust manifold assembly is a genuine factory OEM replacement part engineered specifically for MerCruiser 4.3L V6 EC (emissions-controlled) inboard/sterndrive engines. This manifold supersedes earlier part numbers 8M0053875 and 8M0095466 and comes complete with expansion plugs and a gasket, providing everything needed for a direct OEM replacement. As with all genuine Mercury Marine components, this part is manufactured to original factory specifications — not an aftermarket substitute.
Due to its size and weight, this manifold is classified as an oversize item, and limited shipping options and fees may apply. It is a special-order product that transfers from an alternate warehouse, requiring additional handling time of 1–3 business days beyond standard processing. Because it is ordered specifically for individual applications, it cannot be returned or canceled once the order has been processed. Buyers are strongly encouraged to confirm compatibility with their specific engine model using the engine serial number prior to ordering.
