New to me tracker boat - what to hook up to batteries that I’m replacing

[Thedarktitan]

-I just picked up 2 new batteries for my new to me bass tracker. 2013 175 with 60 4 stroke mercury.
-I am trying to figure out what to hook up to each battery. I have one cranking battery for the motor and one deep cycle for trolling motor.
-What battery do I hook up the livewell and electronics to? Cranking or trolling battery.

Everything except the trolling motor goes to the cranking battery.

Thanks that’s what I thought, but wanted to make sure.
Only the trolling motor on the deep cycle battery and everything else on the cranking.

Always wondered, why does everything go on the cranking battery? Thanks

I have livewell stereo and nmea 2000 power connected to trolling motor battery. Why run down the start battery and get stranded.

That's why you carry a portable jump starter.

Trolling motor will sometimes cause interference on fish finder screens if run off same battery.

Do yourself a favor and run 3 batteries, one cranking and a 24v trolling motor, it makes a HUGE difference.

I upgraded last summer this way and its so much better.
