PRM1750

Full hydraulic operation, drop centre output shaft with two stage reduction gearing.

PRM1750 series marine transmissions are the ideal choice for pleasure and commercial craft applications with engines rated at up to 620 hp (463 kW).

They are available in both shallow and deep case form - corresponding to reduction ratios ranging from 1.22:1 to 3.0:1 and 3.12:1 to 4.9:1 respectively - and are supplied with integral SAE housings as standard.

All PRM1750 series transmissions feature a twin countershaft design compatible with left or right hand propeller rotations - making them equally suitable for both single or twin engine installations. In addition, the PRM1750's two-stage reduction gearing enables maximum input torque of 1750 Nm to be transmitted continuously in either direction at engine speeds of up to 2500 rev/min.

Operation is by a single lever compatible with proprietary remote control operating systems.

The need for special purpose automatic transmission fluid is eliminated by the use of engine oil specification lubricant.

PRM1750 utilises a maintenance-free oil-operated, self-adjusting multi-disc clutches for consistent reliability and in-service performance.

The gearcase is manufactured from high grade cast iron and is internally ribbed for extra rigidity and strength.

The oil pump, oil filter and hydraulic control valve on all PRM1750 models are mounted externally for easy access and servicing.

Two optional clutched power take-offs - compatible with SAE classification hydraulic pumps - are available to drive on-board machinery. Further ancillary equipment for PRM1750 gearboxes includes an oil pressure gauge, oil cooler kit and trolling valve.
