I am in the process of wiring a 15' jonboat with a 1999 25 hp Mercury outboard. I am a complete novice to this, so I apologize in advance if I sound like the village idiot. I was thinking of buying two 12 volt rechargeable batteries - one for the front of the boat and one for the back. In the rear I will have my outboard motor, a night time navigation light, and a trolling motor. In the front I will have a depthfinder, green/red night time navigation light, and another trolling motor. In the future I plan to add an electric anchormate which can be run from either battery. What amperage batteries would you recommend? I know the little 12 volt, 8 amp batteries are cheaper, but they probably won't have enough juice for my accessories. Also - if there are any specific brands or types of batteries you like, please let me know. I was planning on checking out the new Cabelas in St. Louis Friday night and they have some rechargeable batteries that look good. All recommendations are GREATLY appreciated. Thank you!!!!
