I have had about zero time this year to actually use the boat but the last 2 times I have been out the batteries have been flat dead. I went out the first weekend in August.... it sat for a few weeks before that. Flat dead. I took the day off last Thursday and Friday to use the boat and it was flat dead on Thursday again. I plugged it in overnight for Friday and of course all was fine including hanging at the sand bar with the stereo on for a few hours.
I know for a fact the battery switches were turned to OFF between the beginning of August until last Thursday. Where should I start to look? Boat is stored inside now. If I use the boat every couple of weeks all seems fine. I am taking an educated guess that I got the boat like this from the factory because I'm on my 3rd set of batteries because of drainage issues.
