To guarantee reliability and safety during navigation. The ZF 25 A is a marine gearbox with hydraulically operated multi-plate clutches.

Its particularly robust design allows it to be installed on high-performance applications such as:

  • luxury sailing boats;
  • motor yachts;
  • fishing boats.

It is compatible with all types of engines and propulsion systems, including waterjets and propellers.

It resists sea water thanks to a light and robust aluminium alloy case that covers it.

The presence of case-hardened and precision ground gear teeth ensure long life and smooth operation.

It has an output shaft thrust bearing that allows it to absorb the maximum thrust of the propeller both forward and backward.

One of its main advantages is represented by the presence of a fluid and reliable hydraulic cable, with control lever for attaching the push-pull cable.

The oil filter cartridge is replaceable.

Its safety is guaranteed as all its design, manufacturing and quality control standards comply with ISO 9001.
