    Axius Gen 1 Removal

    I haven't helped people to remove it, but I have helped people to put it back after someone made the mistake of removing it! I would need engine serial numbers to help further. Each Generation and version has different issues.

    Merc Smart Craft // 150 Four Stroke - Question

    I don’t have a lot of hands on experience with the new O/bs, so my mind is stuck in the old 2 strokes. Water pressure was the first thing I added to the ones I owned, but I always had an old speedometer and some pitot hose laying around so it was just another hole in the dash —- still have the...

    Merc Smart Craft // 150 Four Stroke - Question

    Happy you got it sorted out! Well mostly I guess, You have "system" gauges. So the speedo is getting it's info straight from the engine ECMs Not sure what you have going on, the system will read 2 tanks, make sure you select "not installed" for tank 2. Other then that, you could try a master...

    Merc Smart Craft // 150 Four Stroke - Question

    What did the VV Mobil do when you connected it? Time to look under the dash (might have to cut a bunch of Ty-straps, it’s usually a mess of wires) and see what’s going on. Looking for any terminator resisters and to see how close it matches the diagram you posted.

    Merc Smart Craft // 150 Four Stroke - Question

    On the engines, is the blue terminator resister plugged into the engine all by itself or is there. “y” harness? ——- should read yellow, not blue. The empty 3 pin system link connectors are normal and will always be there. They are for more gauges if you want to spend more $$$ with Mercury...

    Merc Smart Craft // 150 Four Stroke - Question

    The diagram you posted is how this boat should have been cabled. Here is a link to the part number I posted earlier. https://www.mercruiserparts.com/893452a01-cable-asy-link The cable you purchased was for earlier SmartCraft systems. Other than costing 5X what the correct cable costs, it might...

    Merc Smart Craft // 150 Four Stroke - Question

    update to this thread. Had to talk to Rinda today so I asked if TechMate or Diacom will change engine location assignment on the 70 pin ECM that O.P. has on their motors. Tech support assures me they will. After hanging up, I realized I forgot to ask about if they will also do the newest ones...

    Merc Smart Craft // 150 Four Stroke - Question

    Diacom would allow you to set engine placement on I/Os back with the MEFI ECMs. Don't think it will on this ECM, but don't know for sure. Never tried to hook up anything other then G3 to a Mercury Marine product since G3 came out. I'm just going by the O.P. saying "using a specific tool which I...

    Merc Smart Craft // 150 Four Stroke - Question

    What resistor cap did you remove to plug in the VV Mobil? And where was it? What color was this cap? Where did you put this cap while you plugged in the VV? We are having a communication problem. I'm typing in the SmartCraft language and you're reading and responding in the English language...

    Merc Smart Craft // 150 Four Stroke - Question

    OK, here is my best guess on what's going on. This was NOT common practice on your engines. You should have 14 pin helm harnesses and your port tach shouldn't work. The only way I can see that it could work now, is someone never installed the 2 pin Can P link harness and instead installed two 2...

    Merc Smart Craft // 150 Four Stroke - Question

    Sorry but I'm not 100% on this stuff. Your comment about "common practice at one point" leads me to think these are older engines? If you post serial numbers I can try to help when I have time, but this is something that the dealer who sold you the Vessel View Mobile should be able to answer.

    Mercury Demand, Demand Linear, Demand Guardian

    The S.B. @Fun Times posted is good for your engines (as far as propping ASC) it’s nice because it gives examples that the install manual for your engine doesn’t But on page 35 of the installation manual there is a nice and easy to use chart. Yes, you need to make sure Demand Linear (DL) and...

    Volvo Penta V6-240-CE-J(AQ) Check Engine Code

    OH and one other thing. What is your serial number? The "J" model was a transition year. Some parts different from previous years and some parts different from the next year. There was a mid year break denoted only by serial number. Would probably be good to know what side you fall on.

    Volvo Penta V6-240-CE-J(AQ) Check Engine Code

    "not sure it provides the clarity I was hoping for" Well it did help, you now know that your engine has had. 1. cat damaging misfire 2. stage 2 exhaust overheat 3. engine coolant over temp stage 2 But the trouble is, these problems might have occurred long in the past and been corrected or they...

    Volvo Penta V6-240-CE-J(AQ) Check Engine Code

    Your welcome. I know you don't want to hear what I have to say, but you asked. In my view it's a bad idea to run this boat at all. The EVC system was designed as a control system, so it doesn't display all fault codes. It is just showing you enough to convince you to stop using it and get it...

    Volvo Penta V6-240-CE-J(AQ) Check Engine Code

    Scanner won't do much without the diagnostic manual # 47706663 and the knowledge of how this system works. MID 128 means the problem is originating from the engine ECM. SID 6 means there is a problem with #6 injector driver. FMI 6 means that injector is shorted internally or has a short to...
