i am new to boating and just received a 89 bass tracker and was wondering about the livewell drain i know it is in the lower left back of my boat and would it be underwater the livewell has a drain and for the overflow you attach a small hose to the drain and attach it to the top of the livewell i was wondering how the livewell would drain if i am in the lake if i have the aerator pump running and also wouldn't water rush in from the outside through the livewell drain
