    Replacement Fuel Sender?

    Maybe a tube type sender instead of an arm style.

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

    The new manifolds are a better design, it seems, but the water passages to the riser portion do not seem all that large (to me). I wonder if there is some restriction by design, since I believe the risers also get a raw water feed. As for the faults and codes. I have the Diacom computer...

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

    Not sure why you are calling these 'dry joint', since the the exhaust and water chambers are separated by a single gasket, just like the old style wet joint manifold/riser. The old style 'dry joint' was such that if the water leaked, it would be on the outside on the manifold..

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

    From what I have been able to tell, the boat was purchased in Norwalk, CT July 2016 and owned by someone in Stamford CT, then in early 2020 purchased by someone in Port Washington/Manor Haven NY (just across LI Sound), so it has been in salt water its entire life, but a relatively short life so...

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

    All the terminals are coated with some sort of brown gunk (probably a proper name for it). I am not liking the fact that the wiring is in a cabinet instead of being mounted on a more accessible board. I actually had to replace a bad ground wire for the blower relay, which you can see as a lone...

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

    CATs or No CATS the exhaust on those engines is expensive, since they are Mercruiser's design and not available from aftermarket providers (yet?) You are probably getting close to when the exhaust will need replacement in general.

    Much of the wiring that I need to go through is located in the Starboard electrical panel. The whole thing is going to need some serious cleaning . . . I don't know how it got so grimy in a mere 5-6 years. . . . . . Here is the 40 amp fuse that we have been talking about . . . (Yellow Arrow) .

    I’m surprised it is 40 amps, that seems like a lot. The #12 wires that connect to it would be fire ready before the CB comes to the rescue 🤔

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

    I would really like to find a section of the helm power feed that matches the Diacom ‘Battery’ value (which seems to trail the system voltage by 0.6 - 1.1 volts). If I can find that voltage then I may have isolated the problem. I agree messing with the wires has improved things, but there is...

    Yes, I am wondering if the elements are getting to it and causing a little bit of voltage loss?

    Starboard Engine latest Diacom . . . engine throttles advanced a little bit to get fast idle voltage. . . From Today (August 1) . . . one of the happy power-ups. Also, I frequently get the standby message, both for system OK and for Warning. I do not see anywhere in the VesselView...

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

    The retaining nut is different than the one above it, which matches the rest of the boat's CBs. That is why I was thnking it was replaced. I did not see anything in the work order hisdtory that I have on the boat. So, if it was replaced, probably during the original owner's tenure. (3-4 years)

    Here are some pictures and other information to help address some of the questions. Controls and gauges/displays . . . . . . . . FireBoy/Halon . . . just the light. Not sure if they are connected or not. . . Looks like there is a purposeful feed to the DTS . . . I still have to trace it...

    As for the steering angle indicator, which does not seem to be working, I believe there is a steering angle source selection in the VesselView settings menu. . . . PCM0, PCM1, PCM2, etc and TVM. I will try different choices to see if it makes a difference.

    Here is my morning reading . . . 100's of pages of gripping dialogue. I mostly look at the pictures :ROFLMAO: For any question on the manuals, versions of stuff, etc. Here is what I got. Some came with the boat and some I've acquired. . . . . . .

    Thanks for your comments and assistance @muc and others (y) I have contacted CY Tech Support (via email) regarding the helm power, and have also asked for the diagrams for the V.V. Gas and the Merc Gas cable kits. Those don't seem to be in what they already sent me. I have not noticed how...

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

    Following up on one of the questions about if either engine can charge the batteries. . . . It looks like there is a 2 alternator, 3 battery isolator in the wiring diagram. So, It would seem that either engine can be the source of charging power to the engine and accessory batteries. The...

    This is a little hard to read, but here is the power wiring diagram of the boat that I got from CY tech support.. . . One difference I have noted is that I have only 1 Accessory battery rather than the 2 batteries shown.

    See my answers below . . . 1. Have you tried disconnecting all batteries except engine batteries? I have not, but it would be a good test of my theory on the helm power. I am wondering if I can/should just shut of the house and inverter batteries or actually disconnect them for the test...
