Marine Diesel Keyed Drive Coupling Hub / Jaw Coupling Half - Used

Application: Keyed drive coupling hub / jaw coupling half suitable for driving engine-mounted raw-water pumps, circulating pumps, or small accessory PTO drives on marine diesel engines. Condition: Used — surface rust and light corrosion, drive lugs and keyway intact, no visible cracks. No OEM part number is legible on the piece, so exact brand and engine fitment cannot be verified from photos. 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.
