The YDEG-04N (NMEA 2000 Micro Male connector) is currently in high demand and experiencing production delays. We don't have a firm date for additional inventory but hope to receive them by the end of July. Please use the Notify Me button below to be notified when inventory arrives.
Need one sooner? The YDEG-04R (SeaTalk NG connector) is in stock and connects to any NMEA 2000 network with a few adapters from Raymarine.
Engine Gateway YDEG-04
A gateway that translates J1939, Mercury SmartCraft, BRP Rotax, and Volvo Penta engine data onto your NMEA 2000 network — putting engine RPM, hours, coolant temperature, battery voltage, fuel rate, and alarms right on your chartplotter.
The Engine Gateway is compatible with J1939 engines (Caterpillar, Cummins, John Deere, MAN, Yanmar, and others), BRP Rotax, Mercury SmartCraft, and most Volvo Penta engines manufactured since 2003 — and even some engines built before 2000.
✓ Known compatible engines
- BRP Rotax engines manufactured since 2005.
- Caterpillar — including C9, C18, C30, 3126B, and 3196. Other models may be compatible; send us your engine model, production year, and serial number to confirm.
- Cummins — 480CE and QSC engines. Send us your engine model, production year, and serial number to confirm.
- John Deere — J1939-equipped engines including the 6068. Often identifiable by a Murphy PowerView 101 display.
- MAN — when equipped with MMDS-CLC or MMDS-LC (CAN version) displays.
- Mercury SmartCraft — engines using SmartCraft CAN-P.
-
Volvo Penta — most engines manufactured since 2003, including:
- All versions of EVC-B, EVC-C, EVC-D, EVC-E (most engines since 2006);
- D1 and D2 series with MDI (Mechanical Diesel Interface), e.g. D2-40F;
- EDC III and EDC IV diesel engines (EMS 2.0, EMS 2.2);
- EVC-A MC and EVC-A EC;
- EFI engines with MEFI4B ECU or later (gasoline, 2004–2005), with or without EVC;
- All EGC engines (gasoline, 2005 and later), with or without EVC.
- Yanmar — common-rail engines with J1939 support: 3JH40, 4JH45, 4JH57, 4JH80, 4JH110, and the 4LV150, 4LV170, 4LV195, 4LV230, and 4LV250.
× Known incompatible engines
- All mechanically controlled / analog engines.
- Gasoline electronically controlled engines with MEFI1, 2, 3, or 4 ECUs. MEFI 4B and later are compatible.
- Mercury SmartCraft engines with ECM555 / PCM555 ECUs.
- Outboard engines from Honda, Suzuki, and Yamaha.
- Yanmar mechanically controlled engines including 3JH3, 4JH4, 4JH5, and any model ending in E, HE, THE, or TE.
A note on Yanmar: compatibility is limited to newer common-rail 3JH, 4JH, and 4LV engines. As a quick rule of thumb, any Yanmar model ending in E, HE, TE, or THE is not compatible. If you're unsure, send us your model number and we'll confirm.
Some engines need an adapter cable to connect. We stock a range of them at reasonable prices.
Browse adapter cables →Factory settings suit most vessels with one or two engines. A single YDEG-04 supports up to four networked engines. If your engines aren't linked or networked together, you'll need one gateway per engine.
Works with your NMEA 2000 network
The gateway is compatible with virtually all NMEA 2000 equipment and is certified by the National Marine Electronics Association. Raymarine SeaTalk NG, Simrad SimNet, and Furuno CAN networks are branded versions of NMEA 2000 and differ only by connector type. Garmin uses the NMEA 2000 Micro connector, which is compatible with the DeviceNet Micro connector.
Which connector do I need?
The YDEG-04R ships with a SeaTalk NG-compatible connector; the YDEG-04N ships with an NMEA 2000 Micro Male connector. For any other network, an adapter cable may be required.
