I don't think AD is searching for another boat, having just dropped some serious coin for the new 28 foot Chappy. Just a matter of getting through the teething pains, so it seems.
Often, once you buy a boat (new or used) you are 'stuck' for a while and have to make the best of it.
I miss...
Here are my design modifications that I'll be trying when I am back at the boat . . .
A few minor changes to make the switch over from solar charging to the DC-DC charger based on the engine ignition being 'on' (engines running).
I'll also need to test the starboard alternator to see if it is...
BTW - I'm finding 1.0 - 1.5 voltage loss across some of the electrical junctions/bus bars, etc. . . . maybe 8 year old connections need some freshening up. :unsure:
Thanks . . . it will become a more learning thread than it was.
Anyway . . . I figured something out that I had not really factored into the design. It seems that an alternator connected to an engine has some level of voltage on its output while it is NOT running. Pretty much around battery...
Quick Update . . . after some poking around. I am focusing on the 2-alternator/3-battery isolator. I'm seeing voltage where I don't think I should be.
It is a good thing I put a bunch of CB's in the wiring layout. I can isolate things for testing and diagnostics.
I decided to start the boat engines today. It turned out to be a bad idea . . .
With the engines running the DC-DC charger is powered from the alternator(s) and charging the LFP batteries, and the alternators are also charging the starter batteries.
On the PORT engine:
I was getting some...
Thank you 😀 .
It looks like 'starter' batteries are the next frontier for the LiFePO4 market. I am seeing CCA spec's in the 1000+ Amp range. However, it does not look like there has been much to address the issues of alternator (stator) charging. 'Smart' alternators are better suited. I'm...
A few final touches to the battery project. Boxes and covers in place. I relocated and re-purposed the battery labels.
The system has been working well. The EPEver does have a mind of its own and does whatever it thinks best. :ROFLMAO:

Still waiting for a string of sunny days to...
You probably should get a copy of the Mercruiser installation manual. You can get yourself into a whole world of trouble if you are not rebuilding the transom to Mercruiser spec's in terms of thickness and 'flatness'.
I tend to agree with the comments that the transom may have been rebuilt (incorrectly) at some point. The spec's for transom thickness is 2", which we are not seeing from your pictures.
Maybe take a look at some other re-build threads on this forum as some are similar in design to your boat...
The Admiral does commercial insurance. Rates are up quite a bit this year. I just got my insurance renewal for the summer house . . . it was up about 40% this year. . . . almost :poop: myself :LOL: .
The cars/boat have not gone up much. (AFAIK . . . never actually see the bill...
