    2012 VP 300 C-A Exhaust manifolds getting too hot - DTC 441 & 442

    I think we both end up at the same page. Volvo's new EPC seems to have a few glitchs. Sometimes I will get the page I posted, sometimes I need to refreash the main page to find it. Also noted that according to this EPC, if you want to buy an TPS, you must purchase the throttlebody complete? Got...

    2012 VP 300 C-A Exhaust manifolds getting too hot - DTC 441 & 442

    I use, https://www.volvopenta.com/en-us/service-and-support/your-engine/manuals-and-handbooks/ and paste the serial number. Freshwater cooling was an option this year, not sure if it was a full system or not. DTC 441 and 442 don't show up in the service manual for this serial number. O.P. Volvo...

    Ignition system common failures? 1994 7.4GL

    Google "how to tell if my holley 4 barrel power valve is bad" Guessing you have the Prestolite B.I.D. distributor. The weak points, leaving the key on when engine isn't running (it causes issues with the ignition module), air gap out of adjustment or excessive wear in the shaft bushings. And yes...

    VP 350 V8 Warning Light (Regal 28 Express)

    There are only a few things that will trigger RPM reduction. Trim isn’t one of them. The yellow warning light only comes on with an emissions fault. The engine needs to be scanned. Continuing to operate it could cause expensive failure.

    CEL, Unusual Whine, and Limp Home Mode?

    Good Plan of action. As is @Bondo with the clear jar. I would recommend that you read your owners manuals that will explain questions like the low fuel light. If you don't have access to them, they are available for free download. Regal owners manual-...

    IAC problems

    I have lost the ability to search by HIN. Will need serial number to help further. I spend a fair bit of time talking to someone who repairs ECMs. They tell me most die because of a problem with the engine. Low voltage, high voltage, voltage where it oughtn't be and a faulty component like a...

    DPS-A trim sensor drives me nuts

    There are different senders available and different gauge packages. I fixed one boat that the trim gauge wasn’t working, it was the tachometer that needed to be replaced. Gotta love some of this can bus technology. Intelligent Troubleshooting can be less costly then swapping parts.

    IAC problems

    Yes it looks like the ECM is bad. But it also seems like you might be using the manual for an EGC engine and I'm guessing you have a MEFI engine. The best I can remember the IAC circuit works about the same between these two engines, but Like I said earlier "it's best not to guess on expensive...

    IAC problems

    Hard to comment on this one, being asked to condemn the ECM is big $$$$. I’ve never made a mistake on this, but have had to pick up the pieces when another tech or customer has. Never a good outcome when that happens. Really would like more info. Serial number 4101216623 isn’t recognized as a...

    Four Winns forward and reverse switched

    Sounds like someone replaced the shift cable and got it on the wrong arm in the box behind the shift lever.

    The job of Marine Technician

    If you want to see a little of what it's like. I suggest Justin Lee Marine on youtube. He works for a FL dealer and mainly sees Tiara, Pursuit, Grady White and Regal. Mostly Mercury and Yamaha outboards with a few Volvo I/Os. I did a very similar job here in MN for 30 years and he does a good...

    2016 Mercruiser 6.2 ECT - long beep every few minutes???

    Take what I’m about to say with a grain of salt, I’ve spent all my time working on boats in Minnesota. That’s about as far away from saltwater as you can get. When I saw the pics you posted of the electrical compartment, my first thought was that if I was doing a trade-in or pre-purchase...

    VP DPS-A OXI outdrive with DTC=713

    Your operators manual covers the reset. It's basically what I posted but has a nice picture. Visual inspection for the modual, Yes Diacom will tell you the software package installed to the ECM. But only Volvo tech support or Volvo diagnostic tool --- Vodia --- can tell if it the lastest.

    2016 Mercruiser 6.2 ECT - long beep every few minutes???

    You need to find out what that breaker feeds. 40A is too big for 12ga wire. I've seen some crazy things done with boat wiring. It's highly possible someone put a 40A breaker in thinking it would help with a voltage drop problem. Electrical knowledge is one area a lot of techs are lacking. Also...

    2016 Mercruiser 6.2 ECT - long beep every few minutes???

    Those voltage numbers look normal. Guessing you have an intermittent problem, you might end up fixing it without knowing what connection you messed with was the one! Don't know what "standby" means. Have very little experience with VesselView. The one time I had problems, I just called Merc tech...
