Cast Bronze Marine Water Outlet / Pump Housing - Casting No. 30524-1027 ANW - Used

Cast bronze marine water-passage housing — most likely a thermostat housing / water outlet cover or a pump volute cover. Cast into the part: 30524-1027 and the mark ANW, plus a partially legible raised number on the outer flange rim. These are CASTING numbers, not confirmed orderable OEM part numbers, and the manufacturer and engine application have not been verified.

Configuration: domed bronze body with one large tapered hose neck (approx. 1.5 in nominal bore, to be confirmed), a flat gasket face with four mounting ears (two studs present, two holes open), and one small threaded port inside the dome.

Condition: USED, UNTESTED take-out. Heavy surface corrosion and verdigris, flaking paint, crusted gasket face, corroded studs with two missing. No pressure test or crack inspection performed. Sold as a bare casting — no thermostat, gasket, hardware, or internal pump components included. Recommend cleaning and pressure testing before installation.

Application not verified — sold by photographs, identifiers, and dimensions. Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability.

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.
