Engine Coolant Circulating Water Pump With Integral Outlet Neck And 4-Bolt Hub - Used

Used cast-iron engine coolant circulating (fresh-water) pump with an integral cast outlet neck, small bypass nipple, and a flat 4-bolt fan/pulley hub on a short drive shaft. Application: unverified — the casting carries no legible data plate or part number in its current condition, and the profile is consistent with several small marine and industrial diesel water pumps, so it is offered by photographs and dimensions only. Condition: used take-off, untested. Paint is chipped and flaking, there is surface rust on the hub and mounting flanges, corrosion on the outlet neck and bypass nipple, and old gasket material remains on the mounting face. Shaft, bearing, seal, and impeller condition have not been tested — treat this as an untested unit or rebuildable core. The pump will be drained and its ports capped before shipping. No pulley, hardware, gaskets, or thermostat included beyond what is pictured. 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.
