Battery/wiring help

[wrestlecoach]

Bought a "stripped" boat last fall and am now getting around to setting it up.  Original plan was to add a Blue Sea ACR, but due to layout of boat (25' walk around) I don't think this will work.  The only place to mount a second (house) battery is 9' from starting battery.  From research online this does not sound like a good set up.

I'm thinking now of just running a battery with 2 downriggers (Big Jon), Lowrance Elite 7, and marine radio hooked up to it.  Questions are will this work?  Would a Group 29 DC last all day trolling?  Will the marine radio and downriggers interfere with the Lowrance?  

 

Thanks

i did this same setup with a 21ft Grady several years ago..and yes it did work.minus the marine radio...but the battery was always charged whilst running in on the main motor ,or charged up overnight ,whilst dockside....

Weak wiring to the radio is the cause of a poor transmission signal. You must use 8 gauge wiring, both positive and negative polarity, to power your radio for full 25 watt output.

If you're going to run on a single battery I would want the biggest one I could find. I would look into a 31 group battery dimensions are very similar to the 29. In my old boat I had 2 29 group batteries on a switch, I could run radio, 2 electric riggers, a helix 9, fishawk, and livewells all day and still have enough juice left to start the main. I never actually had to switch to the 2nd battery.
