    Mercruiser 496 won't stay running

    Well...the verdict is a bad trim sensor. Tech says it's shorting out the 5V reference signal. Sent from my iPhone using Tapatalk

    Mercruiser 496 won't stay running

    Well, I went back out and swapped the sensors from one engine to the other. Still no correction. Boat will not start at all and no Spark. Admittedly I haven't checked any voltage on that sensors harness so I suppose the problem could be there. I've all but given up. Sent from my iPhone using...

    Mercruiser 496 won't stay running

    Went out this evening and tested a theory. When you crank the starboard (working) engine, it starts as expected, and you can look at the Smart Craft display and see the RPM's climb from zero and then of course, it fires up. On the non-working port engine as I'm cranking, there is nothing...

    Mercruiser 496 won't stay running

    Interesting turn.... Went to the boat tonight, one by one I unplugged sensors. No results. This time, even stone cold, it wouldn't start. Plenty of crank, no fire. Gauges and Smart Craft all operating as normal (still have the 5V DC LO error). Disconnected a spark plug and tried to test...

    Mercruiser 496 won't stay running

    I had planned on unplugging one sensor at a time (with a stone cold engine) to see if it will eliminate the 5VLo error and hoping that points to the culprit. Good idea or bad? Sent from my iPhone using Tapatalk

    Can you point me to a proper scan tool? Sent from my iPhone using Tapatalk

    Mercruiser 496 won't stay running

    I haven't verified elsewhere, but this season, I replaced all of my batteries so I checked cables etc. No corrosion and great connection. And....the issue was before the battery swap. Sent from my iPhone using Tapatalk

    Mercruiser 496 won't stay running

    Correct. I arrived at the boat, stone cold. Starts and runs for a few minutes and died and will not restart. Plenty of crank, not starting. From stone cold, it starts (and as always, displays the 5V D.C. Lo on the Smart Craft. It runs for a while 5-15 mins and shuts off. Makes me think...

    IAC Valve bad?

    I started a new thread as I replaced the IAC and it didn't fix it. Started fine and ran about 5 mins and died. Will not start/run my attempting to throttle up. Sent from my iPhone using Tapatalk

    Mercruiser 496 won't stay running

    Hey all, I'm still having issues with my port engine. A couple of weeks ago, I started it up. It ran for 15 or do minutes and died. At that time I was able to restart it but it would immediately die again. Eventually it wouldn't restart at all. Today I replaced the IAC since much of my...

    IAC Valve bad?

    Well I'm not really sure if it will run if I try to start it with a little throttle. Im not getting any alarms and didn't when I had the first issue moving the boat a couple of months ago. The only thing I'm seeing on my Smart Craft is an alert for a 5VDC low error.....but that's been like that...

    Satellite TV or No?

    Our greatest use of the KVH on our boat is watching baseball and football games on the hook. We don't use it every time we go out, but I would say 50% is very realistic.

    IAC Valve bad?

    Hey all...I have a rough guess that I have a bad IAC on my port engine. It will no longer idle. Here is the sequence of events this season that leads me this way...its a long one, so bear with me. About 2 months ago, we moved from one marina to another, on the same lake. In that process, we...
