Shop for our full range directly at https://www.yachtagencies.ie/ The PRM500 marine gearbox is purpose 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. To cater for the widest possible variety of boats the PRM500 is offered with a choice of reduction ratios,1.459:1, 1.935:1, 2.565:1 and 2.904:1. All can provide either left-hand or right-hand propeller rotation in "ahead", making the PRM500 particularly well suited to twin engine installations. The gearcase is constructed of high grade cast iron, internally ribbed for rigidity and strength, and consists of two separate halves to facilitate servicing, the oil pump and hydraulic control valves being externally mounted for easy accessibility. The hydraulic operating system functions on normal lubricating oil of the same viscosity as that used in the engine, avoiding the need to use automatic transmission fluid, and ensures rapid response to movements of the operating lever for good boat handling. The operating lever has a positive neutral detent and is suitable for use with proprietary single lever remote control operating systems. Robust and reliable, the hydraulic system is nevertheless provided with a mechanical lock-up device for added security, so that in the unlikely event of hydraulic failure the boat can be brought safely back to port. Access to this device is via a detachable cover located on top of the main gearcase Contact YACHT AGENCIES - by phone 0404 32294 or 087 253 9003 - by email or check out our website with our full product range.
