[QUOTE="BigTerp, post: 464729, member: 9169"] On my boat (Tracker 1648) I run a 24V, 74# Minn Kota Maxxum using 2 Everstart group 27 batteries. I also pull of each battery independently for 12V for stereo, bilge pump x 2, LED nav lights, LED interior lights, sonar, LED light bar, 12V plug x 2 and starter for my '94 Johnson 50/35 jet. Zero issues with things setup the way I have them in my boat. Although this is not ideal since you're not draining the batteries in series equally which is supposed to be bad for their health. But I have not noticed any ill effects of this. I had zero desire and limited room to add a 3rd battery to my setup. The real disadvantage to this is the potential to run the batteries dead with the trolling motor, which I have done once while fishing for 8+ hours running the trolling motor hard. I keep a portable jump starter in my boat for that reason and it works well. With your ability to pull start I wouldn't hesitate to pull off one of your batteries for the starter on your 9.9hp outboard. [/QUOTE]
