Currently I have a group 24 battery and I'm looking for a upgrade. Can I replace my current battery by Optima D27m or D31m? I don't think the size is going to be an issue... The MCA are a little bit higher than my "MotoMaster Nautilus Ultra Group 24 AGM Deep Cycle Battery". Is that an issues or just look for the clearance in my boat?
Thank you
