Marine Shell & Tube Heat Exchanger / Fresh Water Cooler - Used, Untested

Marine shell-and-tube heat exchanger / fresh water cooler, copper-brass construction with bolted end covers, dual large coolant hose necks, two smaller raw-water spuds, one threaded NPT boss, and side mounting tabs with studs. Approximately 20-22 in overall length and 4.5-5 in shell diameter.

Application: not verified. The identification label has been removed from the shell and no manufacturer name or part number is visible, so this unit is offered by photographs, identifiers, and dimensions only. It resembles common marine shell-and-tube cooler families but no interchange is claimed.

Condition: used, untested take-out. Chipped paint and external corrosion are present as pictured. The tube stack has not been cleaned, flow-tested, or pressure-tested. End cover gaskets and zinc should be replaced. Unit will be 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.
