| 500D3 | 2,904:1 | 4,62 | 4,40 | 4,40 |
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.
The PRM 500 gearbox is designed for both pleasure craft and commercial marine applications.
