Condition
Good overall used OEM condition with normal wear from previous marine use.
The manifold shows paint loss, surface oxidation, corrosion, staining, gasket residue, and installation wear, particularly around the exhaust and water passages, mating surfaces, fittings, and mounting points.
No obvious external cracks, broken mounting points, or major physical damage are visible in the photos.
Because this is a used cast-iron marine exhaust component, the internal water jackets, exhaust passages, mating surfaces, threaded ports, and mounting areas should be thoroughly inspected before installation. The manifold has not been pressure-tested after removal.
