Yanmar 3GM30F Marine Diesel Engine Block / Short Block Assembly – Incomplete Rebuildable Core

Yanmar 3GM30F three-cylinder marine diesel engine offered as a partially disassembled block / short-block core. Application: Yanmar GM-series marine propulsion engine as fitted to a wide range of sailboats and small inboard craft — exact vessel application not verified. Data plate reads MODEL 3GM30F with engine number 32179 (partially obscured). Cylinder head is removed; block, pistons, crank pulley, flywheel and housing, injection pump housing and assorted fuel and cooling fittings are present as pictured. Cylinder head, manifold, heat exchanger, starter, alternator, and transmission are not included unless separately pictured. Condition: used, untested, incomplete rebuildable core. It has not been turned, run, or tested in any way, and no operational claim is made. Expect heavy surface rust, carbon and staining in the bores, and a badly corroded fuel lift pump. Ideal as a core exchange, a rebuild candidate for a machine shop, or a donor for GM-series components. Engine will be drained and all open 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.
