Battery for Upgraded Montauk

I have a 2004 Montauk with 90 Saltwater 2-stroke. The boat is pretty much standard. I am getting ready to add:
Bow Mounted Trolling Motor (Likely 24V)
VHF Radio in Console
Already have a FF and Bilge Pump.
Is there a "best practice" way to set this set this up?
Can I use the battery I have and run the bait tank on it?
I aplogize for asking so much, if someone could just point me so I can read some recommendations I would really appreciate it.

That sopunds like a bunch of nice additions! I just finished installing a MinnKota RT55/SP/CP/AP on our 170 and unless you're in a really strong wind the 12volt motor is plenty.With one series 27or31 deep cycle you should be fine.I also installed the MK VSR (voltage sensitive relay) and it seems to really help keep the trolling battery topped off while I run. The other additions probably need advice from someone more knowledgable than me. I also have a 20 gallon KeepAlive bait well,Lms337c and VHF. These are powered by the cranking battery. Probably not the absolute best setup but so far I haven't had any issues with not being able to start the engine. Hope this helps.

Thanks. I am not sure I need a 24V setup for what I do. Just figured I would need it. I have read a couple posts here and there of some saying they wished they had went with a 12V setup. (Single Battery).
I guess if I went this route, I could have (1) Battery for the Trolling Motor, (1) Battery for the Tank and (1)Cranking Battery or do what you do.
I am assumiing you fish salt water?? No problems with the 12V at all??
I have never used a trolling motor, but I fish the shallows around the Chesapeake Bay and I really need it. I keep having to start the motor and it scares the fish and my Mercury doesn't like to be used like this.

Looks like the RT55 is a 48" shaft. Is that length okay. Is that what you have or can you get it in a 54"?

I fish both fresh and inshore salt with the trolling motor. So far I have no regrets about buying the 55# MinnKota. It is a 48" shaft but is long enough except for boat wakes! I don't think you're gonna need three batteries. No more amperage than a baitwell and sonar need to work, your cranking battery should be able to carry the load. If you're unsure about putting them on the cranking batery, you could always get a little larger deepcycle for the troller and run the tank from it also. You mentioned installing a VSR and that is a good idea. I installed the MinnKota unit and it seems to top off the batteries just fine. Hope this helps. If you want pics drop me an email.

I have a 2004 170 Montauk with a 24 volt, 74 pound thrust Minnkota trolling motor. I use 2 Group 31 AGM batteries for the trolling motor. The rest of my stuff is run off of the Group 24 AGM starting battery.
I never use the Minnkota out in the ocean. There is no way a 74 pound thrust would hold my 170 Montauk in any kind of swell.

Thanks Warren. I saw your posts and pics in other posts and I am envious. I appreciate the input, especially on the battery specifics.
Thanks Jerry for sending me the pics of your install of the 12V set up. I like the way you cut the removable mount to contour with bow line and the connector in the front of the console.
I am still a little torn between a 12V set up and a 24V set up. Guess it is up to me now.

Warren has a beautiful setup for sure which also includes a kicker motor .......I couldn't justify or afford to have both. One for the ocean and one for inland ....geez. Again, I've had good luck so far with the 12volt 55# MinnKota and VSR. I had to draw the line somewhere on cost.
