Thank you, Josh !

Some people are gifted with vision, craftsmanship and artistic skills. You are certainly one of them !  Thank you for taking the time to share your work and thoughts on this remodel !  This will certainly be a special boat when you are done.. 

Your thread will live on in the sticky-zone !

Console is primed, she looks pretty good!

Time to work on the inside of the console. I'm planning to lay 2-4 layers of glass, but also going to glass in some of my structural supports and additional hardware. My plan is to have zero holes or bolts/screws exposed on the outside of the console. Using these perforated base 316 stainless mounting studs I'm going to route out a hole inside the coring material and epoxy them in. Then I'll lay my epoxy resin/glass over the top. I'm doing this for the aluminum L brackets on all four sides of the bottom that will be mounted to the floor. I'm also doing 4 of these on each side of the internal walls so I can simply mount a starboard piece to each side for mounting necessary electronics.

Finally!!!! Love the clean mounting idea, and the idea of a replaceable starbaord/mounting boards. This will be especially nice 10-12 years down the road when amplifier footprints change (I know.....I know) or battery chargers, etc. You'll be able to replace the starboard as necessary and not have a bunch of holes to fill or through the console. MBG, take note. This is how us "backyard" OCD fellas do it.

Well some updates, but not much viewing pleasure to be had. I spent a good amount of time finishing up the plumbing in the bilge. Running hoses, installing new drain fittings, thru hulls, etc. Not a very fun part, laying on your stomach all day with your head in a hole. One thing I changed was the primary livewell drain. I despise the standpipe and added a drain in the rear wall near the top, so I can plug the bottom and not have to worry about chasing baits around a drain pipe or redfish knocking into it during a tournament, etc. 

Also put the finishing touches of primer on the console and worked on the front access door. I decided to get a little fancy and build the inside of the door with carbon/kevlar fabric so it would match the other hatches on the boat.

The other thing I'm working on at night is building my own LiFePO4 (Lithium Iron Phosphate) batteries. 

I'm building four (4) 12v 105ah batteries using 16 3.2v cells. I ordered these cells 2.5 months ago from China and they finally arrived last week. I got all of the cells individually top balanced and have started installing and configuring the BMS (Battery Management System) for each one. The BMS provides protection for voltage/current over/under charge and discharge as well as low temp cutoff. Each battery has it's own bluetooth module so I can view all the status of each battery, individual cells, and even historic graphs of the usage. I could have made a single 36v battery for the trolling motor and while it's actually cheaper to make it that way you lose some functionality in the event you need to borrow a trolling motor battery for an emergency cranking battery. You also need to provide a 36v charger which I could do, but again they are not readily available like a 12v if you're in a pinch. I bought 60 amp BMS systems for each trolling motor battery and a 150 amp BMS for the cranking battery. The 150 amp BMS does have a "sparkle current" rate of 500 amps which is more than adequate for starting the Yamaha 250 SHO. 

I'm still brainstorming on the case to house these, but I have some ideas.

Getting closer, one week at a time... ughhh...

It's obvious that the apple did not fall far from the tree.  The tree being the Oak that painted your hull!!!!   So cool to build you're own power system and completely understand how it all works.  Just unbelievable.  

Thanks everyone! I feel very fortunate to have a dad who has always been a "figure it out" guy. Growing up he always made us try & fail until we got it right, or as he's always said "good enough for who it's for". It's a blessing and a curse. We both have the same mindset that we can build/diy anything... but it comes at the expense of trial & error. Sometimes that is costly, mostly with a lot of time and effort to maybe save some money. One major advantage is you almost always learn something and definitely have a better understanding of what you're working with. My dad has an unbelievable gift for engineering and fabrication, but is very technology handicapped. Fortunately for me I was intrigued by technology at a very young age and started taking things apart and sometimes got them working again. ha ha 

I'm now 20 years experienced in the IT Networking field and always enjoy a new electronics project. I wanted Lithium batteries and started doing research. Doing this myself, I'm building 4 batteries for about 70% off retail pricing. If everything goes well I'll report back... if it doesn't... I'll report back anyways.

@MuddyBottomBluz  Good stuff, we have two data centers and use Eaton UPS racks with redundant whole building generators. We're going on 6 years without a power interruption... and I think it only happened then because that's when we installed the latest system. I don't manage the UPS systems, but I know they are crazy expensive. I'm all network these days, firewalls, routers, switches, etc. I used to really enjoy the work and was actually interested in the technology, but these days it's just a job and I'm always thinking about my projects at home instead. Still better than working in the sun all day... that data center stays a nice 65-70 degrees all year round.

I understand the method to your madness, at the Data Center I manage I have 3 banks of batteries with 240 - 2 volt batteries per bank supplying 546 DC volts to each of my 750 KVA UPS units! I can supply 15 - 36 volt trolling motors, just would need a really BIG boat!!!

Game on boys!!!! I'll deliver my battery room pic tomorrow.  Josh, I installed Eaton in a DC that I managed back in 2012 and when we departed in 2017 after one Battery swap it was always a flawless unit.  Redundant system feeding 25 racks of servers and switching and routing equipment.

@whichwaysup Ha ha, I'm sorry about that... I did make some progress today. Finally pulled the boat out in the sunshine for the first time since painting. It was filthy, covered in fiberglass dust. Gave her a quick rinse down and then decided to get the motor rigged up temporarily. The motor has been on a stand for about a year at this point, the warranty expires the end of November 2021 so just thought it would be a good idea to make sure she purred before the warranty expired. 

I also got some new tires/wheels installed on the trailer. The old galvanized wheels looked terrible and the tires were older and definitely didn't trust them for anything further than the local ramp.

Got the inside of the console gelcoated and a few other little things. Back at it tomorrow, standby.

I'm almost afraid to post without much in the way of progress. It's been a busy couple weeks and have only had a day or two of free time. We have a travel trailer and do camping trips pretty regularly. The last trip we took we had two tires go out... one on the way there and one on the way back. One of them blew and the disintegrating tire ripped apart the underside of the floor and caused some damage. So I had to spend a couple days fixing that instead of working on the boat. 

Anyways, I finally got the boat moved back to my house from my dads shop. I think he's having withdrawals and probably cries himself to sleep at night! ha ha, but he's excited to have his garage space back and working on his own projects again. I had to spend a full day cleaning out my garage and cleaning up the mess that magically always appears after a week or two after I organize everything. I still have a good amount of cleaning to do and cannot see any part of the top of my workbench. Ughhh. 

One thing I did this week was replaced the original trailer winch and standard roller with a rubber V-block style bump stop. Even though I had a new roller, I was so worried about scratching up the new paint job. On my old boat, no matter how easily I winch the boat up it would leave marks and eventually chipping the gelcoat. Hopefully this will work better and I can just pull it up tight to the bumpers and not mark up the paint since I won't be driving up on or over them. 

Now that I have the boat back at my house I can start working on it every night after the kids get in bed... that's my free time 9:30pm-midnight or sometimes later. I'm basically tired as a dog all the time, but that's the only opportunity I get to work during the week. As always, I'll post some pictures when I get more updates.
