in the drivers and passangers side of my boat there are switches that control a cable that runs to the back of the boat.. I have scene them before but have never used them or even really payed attention to them. I am trying to figure out what they do. They are on the bottom next to the consoles and are a foot level. its a 96 skeeter zx 180 if it helps.

to fill and empty live wells usualy.

so how do they work

they should be labeled fill,empty,recurculate. while you are out on the water , turn on livewells see if they start filling up. after they fill up , if you have a recurculate poss. on the lever switch to that poss. and turn on recurc. pump, or in the poss. the live well pumps could aso serv as recurc pump. then when you trailer your boat you shoud be able to put lever in empty poss. and the live wells should drain.
