Volvo Penta Marine Reverse Gear Transmission (ZF/Hurth Built) - Used

Volvo Penta marine reverse gear / transmission, built by ZF (Hurth) in Italy — the aluminum case and side cover are cast "VOLVO PENTA" with the ZF logo, and the cover carries casting number 3581603 (a casting number, not a confirmed orderable part number).

Application: commonly found behind smaller Volvo Penta marine engines using the ZF-supplied 25-series reverse gear. No data plate is present, so the exact model, gear ratio, and rating are unverified and are not claimed here.

Condition: used take-off, untested. Complete-appearing case with splined input shaft and bell-housing adapter flange; surface oxidation, light verdigris and rust on hardware, splines and ports. Shift lever/actuator and output coupling flange are not included as pictured. Internal gear, clutch, and bearing condition are unknown — offered as an untested unit / core candidate, not as a rebuilt or tested gear. Unit will be drained of gear oil and ports capped before shipping.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability. 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.
