to be honest im not sure of the battery size im going to have to get back to you on that has a 6 hp evinrude outboard. but pretty much just run the lights and stuff no more then a 2-3 night trip. it would simply be running the lights i don't think any thing else. pretty much most of the overnights will be to an island to go camping but i want to be able to have power on the boat just becuase well you never know.
did you tie the two batteries in parallel or just swapped them out?
like i said worst case scenario i bring my generator and set it up on the dock and use a charger. i was just hoping for something a little more convenient becuase i have seen all these things about water generators and wind ones
