Yacht Devices Engine Gateway YDEG-04N

Yacht Devices is releasing new products at breathtaking speed. Over the last year they shipped a voyage recorder, digital barometer, digital thermometer, text display, and two weeks ago an engine gateway (YDEG-04). Stop the presses! Today Yacht Devices announced another new product, the NMEA 2000 (N2K) network bridge. The bridge is for connecting two segments of a N2K network and for processing messages between them. The N2K bridge is probably available in September.

In “Maretronesk” fashion, Yacht Devices is quickly establishing themselves as the lowest priced source for N2K related solutions. So what does the engine gateway — now shipping — do exactly?

Engine Gateway Features

You might be familiar with competing N2K to J1939 gateway products such as the Maretron J2K100 ($400) or Raymarine’s ECI-100 ($300). Yacht Device’s $189 engine gateway is similar because it listens to J1939 messages from a Volvo or other J1939 protocol based diesel or gas engine. Certain messages are then translated to N2K format for viewing on a multifunction display. According to Yacht Devices this allows you to view the following information if your engine supports it:

  • RPM
  • Total engine hours
  • Coolant temperature
  • Battery voltage
  • Alternator potential
  • Warnings and alarms
  • Coolant pressure
  • Boost pressure
  • Oil pressure
  • Oil temperature
  • Fuel tank level
  • Fuel rate
  • Percent engine load
  • Percent engine torque
  • Fuel delivery pressure

One unique feature that is most noteworthy is the micro-SD slot for software updates, configuration and data logging.  You won’t find this in competitor products.


Included is a 6 pin Deutsch y-connector (male and female) to connect to a compatible engine, so no extra cables are needed. The engine gateway supposedly opto-isolates the N2K network from the J1939 engine to protect from passing high voltages.

On the N2K side you can order the gateway with a SeaTalk NG or a DeviceNet micro connector. On the J1939 side you connect the 6 pin Deutsch connector to the back of a tachometer, helm control unit or multi-link hub – on Volvo Penta engines. Other engines will need investigation as to where or if you can connect to them. There is apparently special support for Volvo D1 and D2 engines.
