Wire size?

What wire size from battery to key switch then from key switch to solenoid? I'm using 12 ga for both.

Depends on how much chit you are running electrical wise... I normally use 10ga.

I use #8 from the battery (use a breaker) to a fuse block behind the dash. From there, I run a wire off a 20-amp fuse to the switch, then on to the solenoid. I use #12 for that run. #8 gives plenty of ampacity for stereo, ignition, lights, bilge, and accessory circuits.

BTW, I'm sure the 20-amp fuse is overkill for the solenoid, but I'm actually trying to protect the wire, not so much the solenoid.

Just the basics. No stereo at the moment

For just a straight up, basic run, you'll be just fine with #12. Just be sure to slap in an inline 20-amp fuse. If you use that run for anything more, go with a #10. Every boat I've bought, I've rewired/harnessed completely. It's amazing how many times I've torn out unfused circuits. Found some pretty crispy wires in the process. Good luck, man.
