Battery wire size ?

#2 should be fine for an outboard that doesn't use a computer, but if you can get it for free, might as well use the 2/0.

I just ran 4 gauge marine tined wire 20 ft in my boat and it works great!! I use to lose so much power when using the trim tabs that the low voltage warning use to go off on my fish finder and GPS, No more.

And if I read this right you are just going from the switch to the battery's so its not going to be long at all, You should be fine
