Yanmar 4JH-Series 4-Cylinder Marine Diesel Engine Core - Used, Incomplete

Yanmar 4JH-series inline 4-cylinder marine diesel engine, offered as an incomplete rebuildable core. **Application:** Yanmar marine propulsion; seller's records indicate a 4JH4-AE, but the engine data plate is illegible in the photos, so the exact 4JH variant must be confirmed by engine model and serial number. **Condition:** Used, untested, partially disassembled and incomplete — block with head, injection pump, injectors, fuel and oil filters, water piping, crank pulley, oil pan, bell housing and mount brackets are present; flywheel, damper plate, transmission, heat exchanger, turbo (if applicable), mixing elbow, raw-water pump, starter and alternator are absent. Surface dirt and light-to-moderate corrosion throughout. No run, compression or pressure testing has been performed and no operational claim is made. Engine will be drained and open ports capped before shipment; ships crated on a pallet, freight only. 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.
