Water-Cooled Marine Exhaust Manifold / Heat Exchanger Housing 3-Cylinder Casting 170-8887-0 - Used

Cast-iron water-cooled marine exhaust manifold / heat-exchanger housing for a three-cylinder diesel, with three exhaust port flanges, integral water jacket, welded hose nipple, and a machined end-face port. Casting number 170-8887-0 with secondary casting mark 3J208.

Application: Not verified. The layout and factory cream paint are consistent with small marine generator-set and auxiliary diesel installations, but no OEM catalog match has been confirmed. Sold by photographs, casting numbers, and dimensions.

Condition: Used, untested take-out. Paint chipped and flaking, surface rust on the exhaust port faces, and green corrosion staining around the water bosses from raw-water service. No cracks visible in the photos, but the unit has not been pressure-tested, cleaned out, or internally inspected. Best suited as a rebuildable core or as a pattern/identification match. Will be drained and all ports capped before shipping.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability.
