1992 Stingray 556z - 3.0 Merc I/O Alpha I Gen II bowrider. The reservoir under the seat cushion in bow, port side, is this supposed to be a live well or a cooler? Not sure what the original intention of this design was. Maybe just a place to ice down some can drinks? There is indeed a thru-hull with a drain plug although it is very ineffective at draining the reservoir. What I'd like to do is make it into a live well.I'd like to utilize some kind of pump to fill it with lake water using the thru hull that is already there. I'd also like to aerate it somehow, not sure I can so so using the same pump. Would also be nice to EMPTY it with the pump back into the lake. Maybe this is not possible with one pump? That's why I'm here, asking you kind folks with all the knowledge! Please rec a pump or any other apparatus that may help me accomplish what I'm trying to do. Thanks a bunch!
