    By the way, I understand that the Gateway will start at about $400 for a single engine. Also, a big thanks to AaronH for first letting us know about this development on an entry about the new Garmin 6- and 7000 series:

    Nice, Ben (and Glen). I saw this and also mounted the Bennett adapter. I think it’s now up to the MFD mfrs to give us more flexibility in what PGN we want to show on the engine screen or better yet, the corner data boxes now avail for other items.

    So, will this be backwards compatable with smartcraft from older boats/engines or just on future production models? I have a 2007 Sea Ray with smartcraft system view and two Raymarine E 120 mfd’s and would very much like to use the Raymarine units for displaying engine info and other stuff that the system view currently displays.

    The Gateway is compatible with all SmartCraft engines, I think. This PDF lists the data points various Mercury engines can send to the MercMonitor:

    I noticed on Glen’s board he has also figured out the new gauge will translate analog tabs directly from the backbone…using the Garmin adapter…

    From the diagram, it shows hooking up a NMEA compatible outboard. Does anyone know if the MercMonitor must have a Merc or will a NMEA 2000 compatible outboard work with it? I’d like to use the EcoScreen but want to use an E-tec or a Honda outboard.

    David, the Gateway PDF you can find at the MerMonitor link above indicates that the gateway will receive as well as transmit NMEA 2000 engine messages, including fuel flow, trim, rpm, etc. However, Verado engines are SmartCraft, not NMEA 2000, and getting the SmartCraft info onto the N2K backbone is the main job of this gateway.
    In other words, it wasn’t really meant to work with an ETec or other N2K motor, but it might. Also, you can get the Eco Screen info from other NMEA 2000 engines in many ways, though maybe not as clearly as the Eco Screen. Once you get fuel flow and speed together to calculate real time MPG, it’s fairly easy to see what trim and RPM combinations are the most efficient for a given load and sea state.

    I have smartcraft running through my Northstar M84 and would like to see if anybody would know if there is anything that i could set up so i could have it running through my ipad?

    have a 7.4 (454) mpi from 2000, will it work ??

    Bonjour, j’ai un 200 verado avec compteurs vitesse et compte-tours SC1000 connecté via passerelle nmea2000 sur un sondeur GPS Lowrance HDS GEN3. Mon pb est que je n’arrive pas à obtenir l’information “to waypoint” (affiche la quantité de carburant nécessaire en fonction de la vitesse pour atteindre le point de cheminement. Visiblement personne de chez Lowrance ou de Mercury ne semble avoir la réponse. D’avance merci pour votre aide

      Sorry, Daniel, I failed French class (twice) but Google translates your comment as:

      “Hello, I have a 200 verado with speed counters and SC1000 tachometer connected via nmea2000 gateway on a Lowrance HDS GEN3 GPS sonar. My pb is that I can not get the information “to waypoint” (displays the amount of fuel needed depending on the speed to reach the waypoint.) Obviously no one from Lowrance or Mercury seems to have the answer Thanks in advance for your help”

      I also don’t have an answer to your question except the generality that many gateways fail to translate some data types from one protocol to another. But maybe a reader is using the same SC1000 or similar with an NMEA 2000 display and tell you if their Go To Waypoint translates. You might also inquire here:
