Quicksilver Exhaust Manifold Assembly Starboard

The Quicksilver 8M0104216 Starboard Exhaust Manifold Assembly is a genuine factory OEM part manufactured by Mercury Marine under the Quicksilver brand. Designed as a direct replacement for MerCruiser sterndrive engines — specifically the 4.3L 262 CID V6 GM engine — this manifold delivers the precise fit, finish, and durability expected from an original equipment component. The assembly comes complete with expansion plugs and one gasket, providing everything needed for installation.

This part supersedes earlier Mercury Marine part numbers 8M0053876 and 8M0095467, making it the current recommended replacement for those earlier manifolds. As an OEM component, it meets all original manufacturer specifications for materials, dimensions, and performance, ensuring reliable long-term operation of the exhaust system.

Buyers should note that this is a special-order item that transfers from an alternate warehouse, typically requiring additional lead time before shipment. Due to its special-order nature, compatibility with the specific engine model should be confirmed prior to ordering, as the item may be non-returnable once processed. It is also classified as an oversize item, so limited shipping options and additional freight fees may apply.
