I have a 175 it has two minnow tanks that recirculate and two live wells that aireate. I don't keep fish but I would like to have one livewell. On bottom of transom it has two wire screens I'm assuming intake and two that have been plugged. I use the minnow tanks for drinks. When I
pull the Plugs water drains in to bottom of boat. Pull drainplug water runs out. Not sure why two holes are plugged any thoughts?
