I am in the process of installing a livewell tank I came across in my 16' jon. I have one pump to pump in fresh water, and have an over flow drain and all, to make it a fresh water system. I also have a re-circ. pump I want to install that will provide aerated water while under way, or trailering from hole to hole. My question is this. If I put a timer on the livewell, what is the best way to run both pumps independantly of one another? Should I put a switch between each pump and the timer, to break control the circut? Or should I have two timers and control them that way? My preference is to have one timed switch that is capable of running multiple pumps, and putting a switch after the timer, to each of the pumps that can control the power to wichever pump I wish to have running. Is that even possible, or should I just get two timers?
