Creating NMEA Network & Interface Yamaha Engine Data

That is a good idea but I am not sure that will work. The jetboats use proprietary can bus data more akin to a car instead of nmea formated data to the best of my knowledge. Your right the data is there in a long string but it would first need to read and converted. There are plently of programs that figure out the start and end of the data string as well as the deliniation. From there someone would need to figure out what each data point was and write code to output it to the nema format for the data they wanted. Problem is we are talking about a custom ic with custom connectors and custom programming for the processor.

In all honesty this is something I could do and build. In all honesty I would have to charge such an exorbitant price for the given market volume that I would probally never sell any.

Now this is one of those cases where I would love to be wrong. If it is nmea formatted already then that does open up some doors. Especially for non-connext boats wanting a nice big touch screen display.

Could you use YDS/YDIS interface for something like that?
Probably not a great idea, but you can run the engines with it plugged in.

It would be awesome if Yamaha themselves would simply add NMEA outputs to their boats! Many companies are realizing that using standards based systems and allowing aftermarket plug ins actually INCREASES their brand loyalty and doesn't diminish their sales (not all brands are like this...cough cough apple cough).

@ClemsonTiger I am not familiar with command link or yamaha outboards. In therory they could share the same data string format and position with the jet boats which would all depend who yamaha outsourced each ecu to. Denso is common for a lot of car manufacturers. Why is everone not the same? Service generates revenue for the dealers that sell their products.

Our boats likely have a pretty simple data string where they are not controlling climate and bunch of other stuff like cars. RPM, time running, total engine time, tps value, error codes, etc is common to pretty much all engines from outboards to inboards. The connext screen on the newer boats has an option where some of this can be viewed. So the question is who has some nema equipment they are willing to try on their jet boat including that cable?

If that works than opens a lot for the weekend tinkerer.

I am thinking a Signal K interface . . . which opens up a lot of possibilities.

Holy old topic revival. I thought this one was dead and buried years ago.

Nema2k is to hard for me to understand,
Is this link something that is comparable ?

This is similar. . . basically the Open Plotter handles the NMEA2000 protocol as well as other Protocols. You can get away from the NMEA2000 network a bit with the OpenPlotter - which makes some things more affordable/and extensible. You can also plug onto the RaspberryPI4 a Moitessier Hat2 Moitessier HAT 2 - Raspberry Pi OpenPlotter AIS receiver - Rooco Austria which should ease some of the connections. What I like is potentially the ability to look at information using a tablet, or phone while onboard . . . versus using more expensive plotters.

Open plotter seems nifty. I will certainly follow any project someone starts on a Yamaha with this. I still question the cost/benefit of interfacing with existing systems on a boat this size. Engine temp is the only thing that I would personally like to see displayed on a main operational display that is not already. Part of the enjoyment of getting out on the boat for me is escaping the data rich environment I live/work in.

Hope yall are well. At least the boat was right out the back door for yall with all the crazy of this year.

Replied in PM.

OK so, I haven't seen anything definitive that outright says, you can't use the Yacht Devices adapter to bring the data into your N2K compatible device yet; which begs the question, what data format do the MR1 Engines use? Is it J1939 or some other protocol?

 

[shaung]

Anyone? I'm betting there are a thousand people who would spend a thousand dollars for this solution. I know I would...

A guy's gotta have goals in life, and you are the king of digging up dead topics.

Please remind us of what anyone would put $1000 value on? really what data is so important that it would be worth $1000 to have on a screen? Engine temp and error codes? Nope, not this guy.



My Simrad connected to a Yamaha outboard powered boat.
Nice, convenient, kinda cool, sure. Worth $1000, heck no.

Easy sell for $1000 - a connext screen is pushing 3-4k. If you could pick up an interface for $1,000 and a 9" Axiom for $600 - you can ditch context and go half price.

Ahh, so like if your connext dies out of warranty? That makes sense.

I was wondering, as my boat is pre-connext, and my Fusion and Simrad can share info, but they sit right next to each other next to the gauges. And I suppose if my analog gauges took a dump, that would be nice to just see that info on the simrad. It's all working now, so no value. But I suppose my values would change it any of those went away.

 

[lazergeek]

The person (@shaung ) throwing the most stink about this lack of function has a pre connext boat, and probably has analog gauges so if he wants it bad enough can just go get analog to n2k adapters and have at it.

The only way I can see this possible working on a newer boat is either reprogramming the Connext to output engine data on the N2k interface which is still relying on the Connext convert the data or someone creates an adapter to connect to the YDS ports for each motor then convert to N2K. Or replace the Connext all together with something to convert the data to n2k. Either way your have to deal with someone creating interface to convert data from proprietary code which is not going to happen unless Yamaha wants to allow it to happen.

You don't need Yamaha - you need a can-bus decoder. Companies do this all the time for cars. I know a guy who works for a company doing this.... but getting the boat in there for my own gain isn't going to happen lol
