Older Models
Over the years the PRM marine gearbox range has been improved and the model numbers have been changed. If you have an older PRM model still in service please refer to the appropriate new model number for more information.
Live PTO
Modern boats, not just fishing craft and workboats but also pleasure craft, increasingly demand auxiliary power for driving on-board machinery such as winches, pumps or compressors. The traditional method of meeting these requirements has been to take an auxiliary drive from the front of the main propulsion engine, which involves expensive and space consuming vee-belt installations.
PRM500, PRM750 and PRM1000 marine transmissions now offer you compact, low cost and efficient alternatives: a choice of clutched or direct drive power take-off units which bolt directly to the rear face of the gearbox, either as factory fitted options or as assemblies for retro-fitting to existing gearbox installations. Both versions are specifically designed to drive hydraulic pumps, whether of the gear, vane or piston type; they are not intended to be adapted for driving an outrigger pulley since the mounting.
