NMEA 2000 Engine Gateway for J1939 and Smartcraft

Transfer engine data to NMEA 2000 network and share it on a chartplotter and other displays.

Monitor engine performance: RPM, motor hours, coolant temperature, battery voltage, warnings and alarms, fuel rate, and much more.

Designed for Volvo Penta, BRP Rotax, SmartCraft (Mercury, Mercruiser), J1939 and other engines.

  • NMEA 2000 Engine Gateway

What engines can be connected? 

First, the vessel must be equipped with a NMEA 2000 network, including Raymarine SeaTalk NG, Simrad SimNet, Furuno CAN, and Garmin NMEA 2000.

Yacht Devices Engine Gateway YDEG-04 is compatible with most modern digital CAN-bus based protocols used on marine engines and outboards motors: J1939, Smartcraft, BRP Rotax, MEFI4B, EGC, EDC III, EDC IV, MDI, Volcano.

The list of compatible engines is constantly expanding:

  • Most Volvo Penta engines manufactured since 2003:
    • All engines with EVC system installed (EVC-A, EVC-B, EVC-C, EVC-D, EVC-E, EVC-2.0)
    •  D1 and D2 series with MDI (Mechanical Diesel Interface), for example D2-40F, D2-55D/E/F, etc.
    •  EDC III and EDC IV diesel engines (EMS 2.0, EMS 2.2)
    • EFI engines with MEFI4B ECU or later (gasoline, 2004-2005), with or without an EVC system installed
    • all EGC engines (gasoline, 2005 and later), with or without an EVC system installed
  • All BRP Rotax engines since 2005
  • All Yanmar engines with J1939 protocol support: 4JH45, 4JH57, 4JH80, 4JH110 and 3JH40, 4LV150, 4LV170, 4LV195, 4LV230, 4LV250, etc.
  • Some Caterpillar engines (like C9, C18, C30, 3126B). Other models also can be compatible (depends on model, production year, serial number)
  • All MAN engines equipped with MMDS-CLC display
  • Some Iveco engines
  • Nanni engines equipped with display panels like SI4 or similar
  • Some of Steyr Motors (equipped with SCC display)
  • Some Cummins engines (depends on model, production year, serial number)
  • Cummins ONAN gensets equipped with NIM module
  • Any other J1939-compatible engine

Which models are definitely NOT compatible?

  • All analog engines (including listed below)
  • All gasoline carbureted engines
  •  Yanmar 3JH3, 4JH3, 4JH4, 4JH5, 4JH-TE, 4JHE and similar models are NOT compatible!
  • Mercury engines with ECM555/PCM555 controller (with ECU part numbers ECM5550204, PCMBE0101, PCM0801, PCM0701, and ECM0501)
  • Yamaha, Suzuki, Honda outboards
  •  Beta Marine engines
  •  MEFI1/MEFI2/MEFI3/MEFI4 engines

What displays and gauges can be connected?

Any multifunctional display which supports NMEA2000 PGNs 127488, 127489, 127505 (and other engine-related messages) is compatible. Monitor your engine performance on: 

  • chartplotter, 
  • multi-function display (MDF), 
  • dedicated instrument display, 
  • digital gauge, 
  • CAN bus display

This output from the engine can be displayed on NMEA 2000-compatible display devices from:

  • Raymarine
  • GARMIN
  • Lowrance
  • Furuno
  • Humminbird
  • Simrad
  • Icom
  • etc.

To access engine performance data on a tablet, phone, PC, MAC, or iPad you need to set up a Wi-Fi network using an additional device NMEA 2000 Wi-Fi Gateway.

What engine data can be displayed?

  • RPM (engine revolutions)
  • Total engine hours
  • Coolant temperature
  • Battery voltage and current
  • Alternator potential and current
  • Engine and transmission warnings and alarms
  • Coolant pressure
  • Boost pressure
  • Engine oil pressure
  • Engine oil temperature
  • Fuel tank level and tank capacity
  • Fuel rate
  • Fuel delivery pressure
  • Percent engine load
  • Percent engine torque
