Cast Iron Marine Cover Plate With Mounting Flange - Used, Unidentified

Used cast-iron cover plate salvaged from a marine diesel installation. Rectangular flanged cover with approximately ten perimeter bolt holes, a shallow domed center pocket, and one small cast boss bored through on the end. Application: not verified — the casting carries no legible manufacturer name, part number, or casting number, and the green verdigris and salt scale on the inside face indicate it served on a raw-water/seawater side (possible heat exchanger, aftercooler, or engine access cover). Condition: used, untested, uncleaned take-off; paint chipping, surface rust on the outer face, gasket residue, and corrosion pitting inside the pocket. Flange flatness and material thickness have not been measured, and no pressure test has been performed. Offered for identification by dimensions and bolt pattern, or as a pattern/core piece. 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.
