Product Specifications and Features

MAR246 is an aftermarket cast-iron marine exhaust manifold for MerCruiser GM small-block V8 engines using the older wet-joint, center-rise, two-piece manifold and elbow exhaust system. It is a single manifold that fits either the port or starboard side and is commonly used on MerCruiser 5.0L, 5.7L and 6.2L / 377 cid applications from the 1983-2002 manifold family.

This manifold cross-references directly to the MerCruiser 860246A15 / 87114A19 family and is also commonly listed against earlier superseded numbers in the same casting pattern. It is designed for the center-rise wet-joint exhaust layout, not the later dry-joint setup. That distinction matters, especially on late 2001-2002 engines where serial-number verification is strongly recommended before ordering.

The supplied kit shown includes the manifold plus gasket and hardware items, including the manifold-to-head gasket, riser/elbow gasket, mounting bolts, and plug / drain hardware as pictured. If you are replacing both banks, order 2x quantity.

Important Fitment Notes

Check before ordering Why it matters
Wet-joint vs dry-joint exhaust This manifold is for the older wet-joint family and will not replace later dry-joint systems
Port or starboard side Same manifold casting fits either side
Single vs pair replacement This listing is for one manifold; most V8 engines use two
Riser / spacer configuration This manifold family is used with different wet-joint riser and spacer combinations
Late 2001-2002 engines Serial-number verification is recommended because changeover years can be mixed
