    Twin Merc. 6.2 Mags with Bravo 3 - EMCT Temperature Overheat Fault - Port side Manifolds (Only)

    O-M-G . . . o_O :oops: 🤪 What those guys said. Raw water cooled. Why was I thinking closed cooling? :unsure: The outsides to look fine . . . so it is a matter of getting a look at the insides.

    Twin Merc. 6.2 Mags with Bravo 3 - EMCT Temperature Overheat Fault - Port side Manifolds (Only)

    Do the engines have Full closed cooling ? or a Half system A picture of the engines would help in that regard. If I were in the situation, I'd be taking the exhaust system apart to see if there is a clog in the passageways which is restricting flow. Salt water running through the new style...

    Find us the right boat

    If you have ever seen an EFI in action, it is not much different than a carbureted engine The fuel mixture still has to travel through the intake manifold and make its way into the cylinders. MPI is injecting the fuel right at the intake port, so it is more precise delivery of fuel in the...

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

    Quick Update . . . Interestingly enough, in my Google searching I have found a couple of documented instances where a faulty trim sender has caused the low voltage alarm on the VesselView. My boat has a bad trim sender on the Starboard engine. So, I'll give that a try to see if somehow a...

    Find us the right boat

    $25K is going to be tough . . . but there are a few boats. 'Trailerable' can mean different things, but I assume you want to stay within the 'no permit required' limits which tends to be 8' 6" beam. (I tow locally a 10' 10" beam boat, but don't tell anybody :ROFLMAO:) A flat deck typically...

    A sea water strainer could be the answer to the cooling system woes.

    Yes, without any signage or such, the 'me first' protocol rules. :ROFLMAO:

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

    The adapter is what costs . . . I could probably upgrade the software now, since it is free. I am wondering if there is a generic equivalent to the adapter cable . . . at a much lower cost. :unsure:

    Boat Ramp Etiquette

    After reading some of this, I am glad that I don't have to launch & haul out on a daily basis . . . The joy of having a slip or mooring. It sure seems like these ramps could benefit from some signage on etiquette or protocol and perhaps even some supervision by the local authorities during the...

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

    Yes, I just checked the pricing on the cable adapter that I would need . . . $249 !!! :oops: 🤪 :rolleyes: Then there is the software upgrade. I might have to save up my weekly allowance for a while in order to get all the bits I need. Do you know if the 3.3 upgrade is free (or minimal...

    It also seems that if you are into 'I.T.' you can't get away from it even when retired. I probably should do the software upgrade on the vesselview4. Installed version is - 3.0.43.349 Latest Version is - 5.0.43.579 😛

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

    There is an isolator of some sort between the batteries and the battery banks. On the 328's it was an ACR . . . it looks like on the 338's it is an isolator. At least that's how it is on the Port engine, charging the inverter bank. My next steps (which will not start until Thursday (back...

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

    Not ready to throw in that towel. Not sure what you would/could simplify without taking all the 21st century features out of the boat. I did enjoy the basics of the 1990's Formula vs. today's boats. I'll go forward and figure it out.

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

    That's a good question . . . Thanks for mentioning it. (y) I'll have to take a look at what little info Cruisers Yachts has about the electrical system and the isolators they use. My solar panel stuff connects to the battery banks directly, but then since the alternators charge more than 1...

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

    Just wondering where there would be a diode voltage drop between the batteries and the engines/PCMs ? :unsure:

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

    Although I disabled a bunch of stuff, I am still getting the voltage warning on the starboard engine as soon as I turn the key to the on position (I usually wait until the VesselView finishes its gyrations before cranking the engines.) The VesselView says that both engine batteries are resting...

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

    I was able to turn off a bunch of alarms, but no limit setting regarding voltage. I read some where that the PCM is spec’d for 9-16 volts. The inverter battery bank is sitting at 13.4 volts vs. 13.1 from yesterday. The port engine is a happy camper, but the starboard engine is a cranky pants...

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

    In reading up on the VesselView, it looks like there are some settings for warning thresholds, alarm silencing, etc. So, I’ll take a look at those first in case some are out of whack. Then onto other things as needed.

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

    Yes, but the message was there before the solar hook-up . . . getting worse though. I could easily disconnect the solar to see if it makes a difference. Also, I should not that while underway the voltages for both engines are between 13.5 and 14.0 volts, per the vessel view. At rest voltage...
