PRM 150
Full hydraulic operation, lightweight, compact & rugged.
The PRM150 marine gearbox is purposely built for use with both pleasure craft and commercial boats; its twin countershaft design provides separate oil-operated multi-disc clutches (which need no adjustment) for ahead or astern drive allowing full rated power to be transmitted continuously in either direction.
