Going through my newly acquired 2001 -181... And I'm curious, shouldn't I have a livewell fill pump and a separate pump for the hydro air?.... I'm assuming the top one is the bilge and the one against the hull is the livewell fill... But pics I found online show the one against the hull is the hydro air... I'm Confused? Any help would be appreciated20181104_160306-1008x756.jpg.
