So I just picked up a new to me boat. It has a raymarine axiom and a yamaha f150 engine. I believe the nema cable is already ran . It goes to the back of the axiom and I can read a few things of the engine with it. What else would I need to hook up the rest ?
I guess you have already added the Yamaha app to the Axiom. My 150 doesn't send all the information that the Yamaha app can display either. I get fuel level and basic engine information like RPM, temperature, pressure, etc. I did expect more than I got but from the research I did, you need the senders to put the extra information on the bus, which are add on extras. I didn't bother, I just turned on the alarms for the information I have.
@@weFishAU I haven't added the app. Will have to look into it. What kind of temps do you see on your Yamaha ? I was monitoring my temps this weekend through what it says is coolant temperature on the axiom but I guess it doesn't read coolant temp? It's actually cylinder temp . If ran hard for good distances it would get up around 230 °f
I had the app on for a while but to be honest I really didn't like it. Nothing wrong with its performance, it was more the aesthetics of the screen layout that I found unbearable. Yes, it reads temperature from a sensor on the head, not the actual coolant temperature. I don't remember what the figures I saw were, its been a while since I removed the app and now I just rely on the alarms to alert me if anything is out of range. So far none have gone off.
@@weFishAU I hear ya. I was a bit worried because it reads hotter with the cylinder temp instead of water temp. Everyone says it should be like 150 max but believe that's water not engine temp
You're not the only one that was worried about that. There was a bit of comment on one of the forums on that very subject recently. My guess is that Yamaha tag the value as coolant temperature when the put it on the NMEA bus.
Hey Mate, Did you end up using the ECI-100 to get stored data on you Axion. I have set up all the same except for the ECI-100 and at this point I don't think I have got the fuel usage details available from previous trips. Have you had to install this or is it still a spare and do you have all your info from the engine fuel use available on the Axiom. Cheers Matt
Yes, I connected it into my NMEA network. I was able to get engine data from my Yamaha and read it on both the Axiom and my Humminbird. I never checked to see what NMEA messages were on the bus so I can't say what the Yamaha was sending but I did get all the basics. I don't recall if fuel flow was on the Axiom, I always checked the Yamaha gauge for that.
@@weFishAU yes I connected up the same except for the ECI-100 and I get flow and battery Voltages but no temps, pressures or fuel consumption data. When I turn it back on the next time to use there is no previous data. The Yamaha gauge still has last trip distance etc.
I already had the Seatalk NG backbone and the Yamaha net so all I needed was to connect them together. I ended up going with a Raymarine ECI-100 to interface the Yamaha Net to the Seatalk NG network. Raymarine charge an obscene price for it but when you are connecting several thousand dollars worth of equipment together it seemed prudent. When I bought it, it came with the cable to plug into the Yamaha net and I already had a space Seatalk spur cable. If both your engines are connected to the Yamaha network then it will interface just fine. I have been told that you can connect them yourself by buying some plugs and wiring them yourself, without the expense of the ECI-100. I thought that was too risky.
I thought long and hard about that. It is an expensive piece of kit for what it does but on the other hand I am using it to connect some VERY expensive equipment. I THOUGHT is would be okay wthout it (if I wired in the right plug) but in the end I decided the risk wasn't worth it. If you ask Raymarine they will tell you that you need it. Since my equipment was still in warranty that was the bottom line for me. Didn't want to void the warranty.
@@weFishAU thanks for the reply! Here in good old Germany a ECI-100 costs about $400 and a new Axiom7 about $650. I think it's a litte bit of a poker game but if you look at Garmin/Lowrance they do it without a gateway. And of course you have to keep in mind that on the "non-secure" side you have your Yamaha gauges and they are also electronic devices ;-)
Totally agree. It is an obscene price for what would only be a printed circuit board and a few diodes to provide the electrical isolation. When you have a captive market I guess you can charge whatever you like. I did read a press release that was dated about 4 years ago that said Raymarine were going to release a cable that would direct connect to the Yamaha bus. I asked several Raymarine distributors about it but they all said they never heard of it.
Your Verado needs to be connected into the Raymarine SeaTalk NG network which is (from my limited understanding) a NEMA 2000 network with different connectors. I think a cable with the right plugs on each end would have worked with my Yamaha but given the price of the components involved I opted to buy the interface unit rather than risk blowing something up. I did see in one of the manuals that the Raymarine Seatalk NG network and NEMA 2000 adapter can be connected to the Mercury Gateway (I guess the Verado uses the Mercury gateway). Talk to Raymarine about exactly what you need. They have a very active and helpful forum at: forum.raymarine.com/index.php They will be transitioning to a new forum in a few weeks but all the information is there.
