The PRM 750 gearbox is a reliable solution for marine applications requiring high power transmission capacity and continuous operation.
Thanks to its hydraulic system, it is suitable for installations with medium and high power engines, both in pleasure craft and commercial applications.
DESCRIPTION:
PRM Newage hydraulic gearboxes are designed to ensure reliability, ease of operation and long service life.
The hydraulic multi-disc clutch system allows full power transmission in both ahead and astern, without the need for adjustment.
The PRM 750 model ensures smooth engagement and consistent operation, reducing stress and wear on components.
SPECIFICATIONS:
Type: Hydraulic
Application: Marine
Usage: Pleasure and commercial
Operation: Hydraulic transmission with progressive engagement
The PRM 750 is available in different configurations to suit installation requirements and system layout:
PRM750A: angled output version (8°) for installations requiring inclined shaft alignment
PRM750D: drop centre configuration with output flange positioned below the input shaft
For correct gearbox selection, it is recommended to always verify the technical specifications and compatibility with the installed engine.

Maximum operating speeds:
4500 rev/min (intermittent) – 4000 rev/min (continuous)
The values are expressed in kW according to the manufacturer’s specifications.
For diesel engines, generally operating at lower speeds compared to smaller units, these values can be used as a reference for gearbox selection, taking into account engine characteristics and operating conditions.
Torque (Nm) depends on engine speed and is not a fixed value.
