    The new alternator works . . . it even likes the DC-DC charger. :D

    Mercury 6.2L ECT Seacore Alternator Replacement . . .

    Quick Update . . . OMG . . . it's working !!! :oops: I ran the starboard engine for a while . . . normal voltages at idle and fast idle. It even likes the DC-DC charger. (y) On to fixing the outdrives . . . :rolleyes:

    Mercury 6.2L ECT Seacore Alternator Replacement . . .

    I went all out and spent $105 on the alternator ( + tax). It is an Arrowhead Electric ADR-0316, aka DB Electrical 400-12299, aka Delco 8600612 In my previous adventures getting new distributors for my other boat, I came to realize that these components, which mostly come from China, are not...

    Mercury 6.2L ECT Seacore Alternator Replacement . . .

    BTW - The rubber band (aka serpentine belt) is a Mercury 8M0088876, which looks to be a 6PK1687 or 6PK1690 generic belt. Mercury P/N sells in the $70 range, the aftermarket belts are about half that.

    LiFePO Batteries ???

    Yes, the solar charging essentially does the float charging, based on its capacity. It does not have enough wattage to do the other stages of charging. In other news. . . I installed the new alternator on the starboard engine yesterday . . . lots of 'fun' . . . see my write-up in the...

    Mercury 6.2L ECT Seacore Alternator Replacement . . .

    Yes, if you take the entire heat exchanger off, it would be a lot easier. . . not sure it would save any time though, vs. just unstrapping it and lifting enough out of the way.

    Mercury 6.2L ECT Seacore Alternator Replacement . . .

    I replaced the alternator on the starboard engine today . . . 6 hrs It looks like the engine was built around the alternator as it is quite buried under the heat exchanger and mounts onto the cross-over assembly. Total nightmare. . . I thought I would document a bit of the process for those...

    Foul Release Coatings ??? PropOne, PropGlide . . .

    Thanks for the info, Scott. It is an I/O or Inboard?

    Foul Release Coatings ??? PropOne, PropGlide . . .

    I did some searching, but nothing comes up regarding "foul release coatings". Major brands are PropOne and PropGlide. These product are supposed to give a slick coating of some sort to propellers and underwater running gear so that marine life (barnacles, etc.) does not grow on them. For...

    Wealth preservation,....

    Once I paid off all my debt, (loans, mortgage, etc.) I was able to save money. So, I guess in that sense I was preserving my wealth :ROFLMAO:

    LiFePO Batteries ???

    In other news . . . In isolating the '1 volt' problem of the electrical system that I have noticed a couple of years ago my attention has been drawn to the starboard side electrical box, which has the appearance of a 100 year old electrical station. :unsure: . . . With all of the rain we've...

    LiFePO Batteries ???

    Tough break for your friend. The BMS within (Lithium) batteries are what manages and protects the battery. That is what needs to be buffered by external components like DC-DC chargers, etc. Direct connecting and forgoing the external components as you suggested would result in a whole host...

    LiFePO Batteries ???

    About half of that stuff is independent of the LiFePO4 swap. What battery are your referring to that has "all the charging system buried inside of it"?

    LiFePO Batteries ???

    Quick Update . . . Things look OK today . . . The sun finally came out, and I have been running stuff on the boat, so the solar controller has work to do. Here is a short video of the status loop of the EVEver controller. First . . . the panel status, . . . . then the LiFePO4, . . . ...

    What about the "No No" rules of solar cells and chargers ? :unsure:

    LiFePO Batteries ???

    This controller (EPEver DuoRacer) is designed for this purpose (solar charging) and it does the 3-stages of charging (Bulk, Absorption, Float). There does not seem to be a way to turn off the float charging, which would be nice, as the LiFePO4 batteries really do not need to float. Tell me...

    LiFePO Batteries ???

    I'm not in love with the EPEver Duoracer . . . charging the LFP bank, the voltage seems to wander up and down, going from 13.5 volts to 14.5 volts and even slightly higher. I'm not sure what it is doing, but I check the voltage at the batteries and sure enough . . . it is wandering. It seems...

    LiFePO Batteries ???

    The solar controller does that. It reduces its output as needed . . . basically creating resistance. The problem is that the solar strength varies, as clouds pass by, so it is constantly varying its output. But the solar controller attempts to go through the bulk, absorption, and float stages...
