First of all I know Banded_Mallard put a fuse from the engine to the control box. Was it something like a 20 amp?

Also I plan on redoing the wiring out of the control box to the engine (water proof plug). What ga. and what would be best for a salt water runner?
Thanks much, Wayne

I used 10 and 12 gauge thhn for the control box. 10 for the primary power and ground for the ignition switch, 12 for everything else. It's overkill for sure. I have fused distribution blocks at the batteries, don't have anything daisy chained off the motor any more like pd sets it up.

Yep, I used 12ga.
