Can someone review my boat wiring diagram?

[CarleyC4]

Hi guys!

I'm looking to install Blue Seas "Add-a-battery kit" on my Key West 1520CC. I'm a visual learner, so I created this diagram to plan the wiring. Can someone review it and let me know if I need to make any changes? I'm open to any suggestions! Also, what size fuses should I get for the fuse in between the battery and the M-ACR?

Thanks in advance!

A little background info, if it would help...
See this diagram for how it's currently wired. What I'm trying to accomplish is having two separate batteries - one for my motor and one for everything else. I would like to be able to relax on the water and listen to music without worrying I'm draining my batteries and won't be able to start my motor to get home. I was told that the way I currently have it does not accomplish this goal and I'm essentially using both batteries continuously.

Buss bar for ground is good, note it can come from the Neg side of the Bat or from the Neg side of the fuse panel

If you want to connect and forget you want to use a ACR. This way no need to switch Bats. The switch is there to be used ONLY when needed to start motor and the normal start Bat doesn't do it

In this setup, the electronics comes from house to the fuse panel and is charged when the motor is running, or when Bat charger is ON

Are your sure about the wiring of the bilge pump? Your diagram has it powered all the time

what is up with the two accessory boxes?
