PRM 500 Gearbox

Full hydraulic operation, lightweight, compact & rugged.

The PRM 500 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.
