Marine Transmission Case / Housing with Shift Lever and Cooler Port - Used

Application: Marine transmission / marine gear main housing (bell case) with integral oil cooler port, cooler line fitting, and external shift lever assembly. Appearance is most consistent with a Twin Disc MG-500 series marine gear; ZF Hurth and Velvet Drive are alternate possibilities. Suitable as a replacement case or rebuild core for inboard diesel pleasure and commercial marine applications. Condition: Used take-off, sold as-is as a core / rebuildable housing. External oil film, dirt, and light surface corrosion present; machined surfaces appear serviceable. Data tag present but not legible in photos; positive ID requires stamped/cast numbers on the case. Any residual fluid will be drained and 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.
