Thank you Noah for your feedback. I already have few people interested so for now will stick to the listing price. And of course it's negotiable. I fully understand that I am taking a big loss here. The only reason why I did the upgrades is my plan was to keep the boat for 10 years and then sell it.

I am looking at a somewhat similar set up.  I am curious why you want a separate charger.  Victron makes a multiplus 12v/2000w/80amp inverter/charger.  This saves at least one pice of equipment to find a place for. 

The 2k W multi in my build will live at the VERY back of the hanging locker to allow it to still work as a hanging locker.  From that spot to the battery box, 4/0 wire will carry sufficient ampacity for the device.

The c34's batter box is frustratingly small.  I do believe two of the 200ah batteries from victron will fit in the box.  The hard part will be the fusing.  The victron lynx bms connected to a lynx distributer will not fit ANYWHERE in the batt box with batteries installed.  Thus, you'll need to get creative with how you arrange it all in there, or perhaps move some of that equipment out of the batt box.

The last item to consider is your insurance company.  I found that my current carrier would allow LFP batteries but that a receipt from a marine electrician who installed the battery was required along with the equipment being sourced from a supplier with a US presence.  That would not be too hard to accomplish with victron.  Finally though... the insurance company would increase my policy amount by 35% !$@$@#!!

I have spoken to my broker and she believes she has found another company that will work, but I am still sorting that out.

Thank you Stu. I was thinking about the chart table locker and wondering about the cable run. It sounds like the Mk II is very different from the Mk I.

I've read that article and, frankly, I think it's safer (for me) to find an electrical engineer to do the installation.

Before that I just wanted to try to work out where everything could go.

Tom : I wouldn't do anything until you get the Bimini on - because that will change the air flow and may solve the problem?!?

Might be worth rechecking that you are not getting exhaust from INSIDE the engine compartment!!

A few thoughts

It looks like you have a nice, clean, 1988 C34 MKI. Since you asked for feedback here goes. Regardless of all the "upgrades" and money you invested in her—- unfortunately, in my opinion, your boat's value is $45k TOPS in today's marketplace. If you want to sell it you need to significantly lower your price.

The batteries wouldn't be a problem, but the inverter is a big beast.

KG, in 1998 I installed a big, heavy Heart Interface Freedom 15 I/C.  I, too, was struggling with location.  At the very same time, Capt. Al Watson in Connecticut was doing the same with his Freedom 10.  I was in California and we "met" each other on this C34 website before the forum began in 2001, so we did it by email.  We agreed that the most opportunistic location was under the nav station desk.  Both of us chose to mount it on the sloping side of fiberglass on the outboard side.  On our Mark I boats that is NOT the hull, but a completely separate wall of fiberglass before the hull with a large air gap between.  Since then I have read about some skippers using the wall between the hanging locker and under the desk, too.  We chose that location because it was close enough to the battery box to run the heavy cables from the I/C through the macerator compartment, under the cabin sole, to the battery box.  Here's Al's writeup from the old Projects page in the pre-forum static website:

The very best primer for lithium systems is Maine Sail's on his marinehowto website. also has a good lithium section, trust contributor "jedi" above all others, he knows his stuff.

Please be warned:  The amount of misunderstanding of basic battery technology, even before the complexities of LiFePO4, is simply astounding.  Many people didn't understand how wet cell batteries got charged, what acceptance is, or how alternators and regulators work, even before LFP.  Couple that with LFP and BMS and you end up with the blind leading the blind asking increasingly inane and ridiculous questions.  So, when reading on this subject, carefully consider the sources; the good ones like Maine Sail and jedi are worthwhile.  Most people asking seem to have avoided Maine Sail's 101 completely, and keep reinventing the wheel.  I also continue to get a kick out of people putting in huge LFP banks with tremendous acceptance rates and then limiting their charging ability by funneling it down with wonky small 30A dc-to-dc charger, when a 400 ah LFP bank could easily absorb 150A all the way from 20% to 95% SOC.  Why bother?

Hi Tom, It's sometimes referred to as the "station wagon effect". Depending on weather conditions, the engine exhaust can roll up over the transom into the cockpit.

I know you said you don't have a bimini, but I first noticed the exhaust fumes after motoring a long time one day after installing my bimini and connector. Never noticed it before. I removed the connector and vast improvement, but still a hint of it. I checked my exhaust system and it seems fine. I haven't been able to get to the boat in months for various reasons. When I do, next steps are to:

recheck my exhaust system.
add fuel injector cleaner (maybe poor combustion).
if still noticeable install my aft weather cloths to see if that helps.
If still happening call a diesel mechanic to have the system checked out.

 Kevin, I am out on Catawba at Catawba Moorings. I would be very happy to share the expense of the removal tool with you. We are only 3 or 4 miles apart and this would save some time for moving the tool around this spring.
 I look forward to hearing from you.

I would like to use this tool again.  If the current "owner" could contact me, I would appreciate it!

I don't have any good suggestions for you.  I would suggest that you make doubly sure that there isn't an exhaust leak.
