Marine engine controls & instrumentsMurphy displays, instruments and control panels are used in marine applications from leisure cruisers and sailing yachts through to commercial vessels and workboats.

Our product range includes:

  • Marine displays, gauges and control panels for the latest ECU-driven, J1939 and NMEA2000 CANbus compatible engines and devices.
  • Environmentally sealed, mechanical and electric gauges and Swichgages for non-ECU/CAN (mechanical) engines.
  • Single sender, dual gauge instruments for engine room and bridge.
  • Marine engine monitoring systems, including gauges, controllers and custom panels.

For the vessels with the latest CAN (SAE J1939 and NMEA2000) engines and control systems, Murphy offer:

  • HelmView and PowerView® displays. Environmentally sealed front and back, with bonded screens for ultra-clear day and night visibility. Choose from standard plug-and-go models, or use our PowerVision Configuration Studio for total OEM control of display graphics and integration with your vessel's CAN, engine and control systems.
  • PowerView® analogue gauges, in a range of lens/bezel styles and colours, give additional 'at-a-glance' indication where needed. Fit to the bridge and/or engine room using a simple 4-wire CAN or RS485 network.
  • Input/ouput modules: integrate your vessel's CAN and Power Distribution systems with switches, sensors, controls and loads.

Our J1939 and NMEA 2000 compatible components are also available in full integrated panels for sailboat, motor cruiser or workboat builders. Murphy can supply both standard, 'plug-and-go' models or OEM-specified custom panel solutions.

For traditional (non-ECU/CAN) engine technologies, Murphy provide electric and mechanical instruments and components for the monitoring, control and fault protection of engine 'vital-signs': pressure, temperature, fluid level, speed and vibration.
