Product Specifications and Features

MAR746 is a Recmar replacement wet-joint exhaust manifold for MerCruiser GM-based V6 marine engines. It replaces the original MerCruiser 99746A17 manifold family used on 3.8L and 4.3L V6 applications.

This cast iron centre-rise manifold is used on either the port or starboard side of compatible MerCruiser 229 CID and 262 CID V6 stern drive and inboard engines. It is built for the older two-piece wet-joint exhaust system, where the exhaust elbow/riser seals to the manifold using the wet-joint gasket layout.

This listing is for the V6 wet-joint manifold family only. It is not for later MerCruiser dry-joint exhaust systems.
