Hi, I bought a 15' Gatortrax boat for use on a 200 acre lake. It has an 8hp pull start motor, so there's no need for a cranking battery. The trolling motor is a 12v, so there's also no need for 24v wiring.

However, I am adding a fish finder, voltmeter/usb charging port, and onboard charger - and a second battery. Additionally, the boat came pre-wired with nav lights, a bilge, and some led lighting that I also need to wire up. I mocked up the diagram below and would really appreciate it if anyone of the electrical gurus could give it a quick review.

Additionally, between the battery and the accessories buses, I was considering a battery switch, just to keep the voltmeter/usb charger from draining the battery when not in use.

Looks good just be sure to use the appropriate sized fuses. Do you know how much current the trolling motor uses? I know nothing about trolling motors but hopefully the battery will have enough capacity to run it all day.
