Default Rewiring battery setup

I'm running a dual battery setup on each Yam 225F. The factory set up the house curcuits on an extra Perko switch wired into the starboard battery system. This puts quite a drain on the starboard battery system when you run electronics and baitwell pumps all day. The house panel is divided into two switched and fused legs. I'm thiking of rewiring the house system to supply each side from the port/starboard battery systems. I think this will allow a more even distribution of load and allow me to "manage" battery recharging and loads. Each side of the house pannel has it's own switch. Is there a better way of handeling this?

There are two batteries per motor? I don't see why your plan wouldn't work. Although I would probably rather have a dedicated starting battery for each motor and parallel the other two for a house bank. Keeps 'em separate.

The F225 has an auxillary charging lead. You can charge one house batt from the stbd engine & the other house batt from the port engine

Assuming even distribution, you can connect each (of the 2 house batts) to 1/2 of the DC panel

Thanks for the replys.
I'm not too worried about starting, the way we fish we never turn the engins off but when drifting or trolling lots of electronics can suck the house system down. Dedicating to starting is too much rewiring, think I'll split the system. I got use to keeping dual battery systems charged from years of running off shore with a single engine.

Birdman,
I got the dreaded red "x" for your picture. I've been away for a while remodeling the old farm house. Good to see you're still active.

Birdman,
Your diagram appeared when I went back to the forum from the reply.
Thanks

That would be an indication your house system isn't big enough to meet the demand placed on it. More batteries, and/or bigger batteries, regardless of any wiring you do.

Eyball,
The batteries were 3 years old before I notices the weakness. I installed new ones last year. I installed the highest amp that would fit. Hopefully, rewiring will make the system more durable.
