Marine Diesel Engine Thermostat Housing / Water Outlet Cover - Used

Used marine/industrial diesel engine thermostat housing / water outlet cover with integral hose-connection stub, rectangular 8-bolt mounting flange, and a small auxiliary top port. Application: manufacturer not confirmed from the photos — the casting style and green paint are consistent with Detroit Diesel 2-stroke or Volvo Penta cooling-system housings, but this has not been verified; sold by photographs, identifiers, and dimensions only. A partially legible cast number is present on the flange edge and is a casting number, not an orderable OEM part number. Condition: used take-off, untested. Chipped paint, surface rust, gasket residue, and light corrosion on the sealing faces; no thermostat, gasket, or hardware kit included beyond what is pictured. Not pressure tested. Approx. 11 x 7 x 6 in, approx. 8 lb shipping weight. Drained and 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.
