Full hydraulic operation, lightweight, compact & rugged.
The PRM 260C gearbox has been replaced by the PRM 280D gearbox. The PRM 260C in-line gearbox is still available.
The PRM 280 gearbox is purposely built for use in both pleasure craft and commercial boats; its twin countershaft design provides separate oil-operated multi-disc clutches (which need no adjustment) for ahead and astern drive allowing full rated power to be transmitted continuously in either direction.
The PRM 280 is offered in two different configurations; power take off (PTO) and with offset output shaft (PRM280).
