I am considering adding a second battery to my 1999 17 Outrage II. I had an experience last season were I arrived at the marina and found my 2 year old battery was dead and I needed to borrow the yard’s booster. There appears to be enough room under the console, although it will get a little tighter with 2 boxes and additional cables.
Does anyone have view on adding a second battery to a boat this size? I am curious if the additional weight, lose of space and cost of switch, cables, etc. will be worth it or should I just have my own booster on standby in the car?
