Hi All,
I’m attempting to determine if the very limited engine data displayed on my 2022 Garmin 94SV and 93SV is what it is “should” be.
In summary, I am getting some data, but not what I expected - doesn’t even show engine oil pressure!
My Key West 179 FS/Yamaha 115 was rigged with Yamaha Command Link (115 is not CL+ capable) components - there are no gauges, just the two displays:
- Yamaha engine cable to Yamaha Hub (6Y8-81920-01 - photo)
- Yamaha cable to Yamaha Gateway
- Yamaha gateway (6YG-8A200-11 6YGA1064270 - photo) to NMEA 2000 backbone - photo).
I get graphic presentations on both Garmin displays (see photos) in two screens (must select the second):
- Screen One - rpm, fuel available, fuel flow, engine tilt
- Screen Two - battery voltage, engine water temperature
I get numbers offerings of about two dozen parameters in the presentation of rpm, engine fuel rate, as well, but the only data that shows with engine running is the same temp and fuel flow (see photos).
I have reviewed the Garmin manual and it shows that engine and fuel parameters “should” be displayed (engine PGNs 127488, 127489, 127493, 127498 and fuel level PGN 127505). I updated the 94SV and 93SV software, JIC, but no change.
I asked Garmin if the 94SV and 93SV “should” show more data - they have been responsive and asked me to send in microSD with download data set for them to review, but I have not been able to get them to tell me what “should” show - I provided photos of displays to them.
So:
- SOME data shows and is accurate, so the data cable from the engine to the hub must be working and is plugged into the correct connector
- my understanding is the hub is just a hub to allow other devices to be connected
- the pigtail from hub to the gateway should be just a pigtail to get data to the gateway
- the gateway’s function is supposedly to allow, “certain engine and boat data to be displaced on NMEA-2000 compatible displays that are external to the Yamaha system …”
In 2017 I rigged dual Garmin MFDs, with a Lowrance data cable direct to the N2K backbone I had installed (no hub, no gateway) - I had a lot more data showing. These MFDs were a bit more capable, but also called for the same PGNs to be displayed as the 94SV and 93SV.
Questions:
1. Is the hub and gateway necessary to get engine data to the MFDs?
- I think the answer is no
- should I get a Lowrance cable and try it from engine direct to the N2K without the hub and gateway?
- should I get a connector - TBD - from the hub to the N2K, taking the gateway out of the data path? (this would seem the same as a Lowrance direct cable)
2. Is it possible the Gateway that was installed from the factory in the boat is the wrong gateway?
- I don’t know the answer to this, but some indicate this may be for CL+ systems, only?
3. Is there anything in my current configuration that would preclude getting more data and/or more comprehensive displays?
- I don’t know.
4. Are these Garmins - 94SV and 93SV limited to what is shown in the photos, even though more data is being delivered?
- I don’t know. I was hoping someone would have a like engine-MFD configuration and could comment or provide photos?
- Garmin, thus far, has not answered as to what I “should” be getting on these specific MFDs
I really need some help - I can still boat since the motor/key has built in temp and oil pressure notification - aural, not visual, but ...
Thanks!
