Update Yamaha to NMEA

[Bmcinc]

I have a 2005 Yamaha HPDI 250 vmaxx. I am trying to update my electronics to NMEA. Yamaha says no, but I've been told by others someone can make an adapter that works. Mine has the white 4 pin plug required, but Yamaha says the cpu isn't compatible. Apparently mine was the 1st year they were switching over and some can and some can't. Any thoughts or help would be greatly appreciated.

if yamaha says no and your motor doesnt support NMEA 2000 backbone. your only other choice is to double up the engine sensors on the engine and add a NMEA 2000 engine gateway. or not go with NMEA gauges or sell your motor and buy a newer one

Yamaha Command Link (NMEA 2000) was introduced in 2006 EFI four stroke and HPDI two stroke production year models. A 2005 model year motor was not supposed to have Command Link capability. But some still got it. Partially or in full.

What are the numbers on your ECU? What is the part number of the engine wire harness?

Why not connect the Yamaha Command Link connector to an NMEA 2000 network connected to your MFD and see what is to be seen? You might be pleasantly surprised.

If you have the correct main wire harness, but not the ECU, then you can buy and install a surplus ECU from Ebay or similar.

Is it just that simple, buy a different ECU and plug it in? Will the plugs be the same? Is far as pin location. I've been trying to get that answer also but no one seems to know. And Yamaha won't tell you anything In fear you might mess something up I guess.

What do you mean by double up the sensors?

What do you mean by double up the sensors?

if your ECU doesnt support it, you can run an add-on gateway and run separate sensors for oil pressure and water temp. many ECU's dont like to share sensor signals.

I'm an idiot when it comes to this stuff. Is there a link or something you can share to explain this? Where would these sensors connect? Where do they get power? How would they connect to gateway? Etc

however lets step back, what is the reason you want to jump to NMEA backbone, then lets go from there.

Too bad the serial number of the motor is unknown.

You don't like the answer that Yamaha gave you. Yamaha USA I presume.

All Yamaha USA can do is to tell you that motors prior to X should not have it and that motor Y, and subsequent to Y, should have it.

Yamaha USA is not the motor maker. Yamaha Japan is the motor maker. Yamaha USA is just a distributor. There are many things they don't know. Can't care to know. Should not care to know.

Then you come here and seem to question answers to your questions.

 

[boscoe99]

Find the other that told you that it will work with an adapter. Buy the adapter. Plug it all together.

I am just trying to simplify my dash, clean it up. Redoing everything and would like to go to an all in one gauge like the 4" one simrad has. Or something like it.

I'm not questioning anything, trying to learn. You guys clearly know more about this than Yamaha usa does. Those guys just make matters worse, and every tech gives a different answer.

there are analog 4 in one gauges. if that is your goal

I tried to look for that also. But I only keep finding these cheap Chinese made ones. I've called shops locally around town and no one seems to know anything. Do you know of any certain ones that are reliable?

VeeThree or Faria make most of the gauges on the market. VeeThree sells aftermarket thru Sierra brand here on iboats

Awesome. Let me ck these out

So I looked at all these and the veethree deepvee tach with fuel is what I would be looking for. Can't find where they are sold anywhere. I guess I'll call them tomorrow and see what the deal is.

I am curious about the Noland cambus link you sent me. Will that hook to my motor and allow me to go straight to nmea gauge?
