Default 2 outboards, 4 batts, 2 add-a-battery systems?

PICTURE of my WIRING now posted in lower POST, please give me some feedback!

Ok so im trying to figure out the absolute best way to wire up my battery system,
I have a pair of Yamaha 2008 200V6 Ox66 outboards, 4 batteries, and 2 sets of the Blue Seas Add-a-battery systems.

id like to ideally
have 1 dedicated battery for each engine,
and have the other batteries combined In parralele to act as my house. but I want to have it wired so that in the even of an emergency I can use the house in combination with either PORT or STARBOARD systems.

Is this possible?
any quick advice or wiring diagrams ?
have checked on Blueseas site but cant find the proper info.

Why not leave ur wiring the way it is split the house load between the 2 other batteries and wire a single on/off switch to be able to combine both main switches.

Check this info from BlueSea:

Review the 3 Battery 2 Engine setup.

PS. We'd appreciate if you can list down what you already have like Switches (what kind, please specify), ACR (or none).

This is what im attempting to do



^^^ is there any Dangerous FLAW in my setup?
I currently Have
2 Yamaha 200 ox66 oil injected
2 starter batteries
2 house batteries
2- Bluesea 7650 SYSTEMS ( 2 switches and 2 ARC's)
I already have all the crimped wiring for my proposed setup, so i was trying to avoid having to buy more wire, but i just wanted to be sure what im doing is SAFE


This is what Blue sea has as one of its options

You do realize that each engine has two seperate charging systems? In other words, each engine can charge two batteries totaly independant of each other. So there you have 4 seperate charging systems. One for each battery.

@chongster4u

What you designed is OK based on your requirement of Starting Battery to Parallel with House should the need arise. BlueSea's diagram will parallel both starting batteries instead (which is not what you wanted).

When did the Ox66 get the isolator lead capability such that it can charge two batteries at the same time?

Those diagrams make my head swim. Much too convoluted for jethro's simple mind.

Jethro likes simplicity.

I am trying to figure out which position the left most switch should be in so that both start batteries are connected to the motors, independently of each other.

They may be safe but good luck trying to figure out which switch needs to be on what setting in times of high stress.

they both turn to "on".... it's as simple as it gets.

the set up is fine. the only thing I would change would be running a house jumper from one swtich to the other instead of running from house battery to each switch. there is no point to running a wire from each house battery to each switch. it's just more cable.

you should also have fuses on the acr lines at each battery. I would also fuse all the main cables as well. MRBF's are great for this. the starting ones would need to be big. (same with the house as it can start as well)

All OX66's I have ever hooked up had them. Make things much easier than what is described above.

I went with the Blue Seas diagram for my purposes. 2 house batteries connected in parallel for all electronics and seperate batteries for starting each engine. Just open switch for engines when anchored for the day or night so no chance of dead batteries when needed. Stereo with amp running and an led anchor light at night, possible under gunnel lts or spreader lts would be the load if needed. Just came back from a little 4 day trip and no worrys.

I see that now. A double pole single throw switch.

Question is, how do you turn on just one motors battery with this type of switch?

you can either just hook up 2 of the leads on the 3 bank and the acrs will kick on once the house is high enough and charge the house or you can hook the 3rd lead up to your house and since they are paralled will charge both. i have 5 batteries on 2 banks and just have 2 leads hooked up since i have 2 batteries on one bank and 3 on the other. they all end up being charged.

So, now that io have my Pro mariner Sport 20 PLUS in hand, im not seeing any wiring where they recommend to charge a bettery bank in Parallel whilst simultaneously charging single batteries on the 2 other banks.
Is this a problem? if i charge each start battery with one bank from the charger and on the third bank fromt he charger im charging the house batteries that are in PARALLEL?
