Looked for an answer but with no luck.  I have two switches for live well control (Aerator) and (Re-circulator).  I caught a fish put in live well with some of that catch and release, flipped the switch for re-circulate.  Checked back in 2 min barely 2 inches of water, fish was on his side just laying there.  So, i picked him up put him in the lake and waited for well to fill again. 

If I am not mistaken sounds like Areator pulls in new water and re-circulator pumps in water from the well.  Why would it drain?  I used the Catch and Release just to have it drain out.

For the remainder of the day, about 1 hour, kept both pumps on that turned off and on routinely, but there has to be a way to keep the water in the well until I am at a good spot to re-fill with clean water.   

Rubber plug.

Put the plug in.

Let me guess...you have a Tracker PT175? Mine does the exact same thing. That stupid plug that comes with it comes out VERY easily and drains it.

The OTHER thing I noticed, If I am WOT and the aerator runs, it empties the well. I run it on recirc when I am trolling still then turn it off when I scoot.

Not sure if its a custom livewell or a stock livewell?  But you have to be careful, sometimes water can syphon itself out if a livewell is not setup correctly.  Wouldn't think a manufacturer would set it up like that, but just something to think about.

Plug would be my first guess.

So there is an additional plug than the main plug that i take out.  Sure wish BPS would have showed me that.  And yeah its a pro team 190.  I know i had some bags with manuals in them and maybe there is a plug in there.

Thanks for help.

Tracker PT series livewells have a handy feature that allows you to use the recirc pump to drain the livewell (much faster than draining by pulling the plug.) The downside is that if you forget about to put it back in the proper position you can inadvertently drain your livewell. I've done it several times.

Make sure if you are using the recirc pump that the nozzle is in the right position. The nozzle pushes in and pulls out and I can't recall which one is drain and which one is recirc (boat isn't here or I'd check for you) but I think pushed in is the drain position.

PS:  after re-reading your post, I would bet that what I stated is your issue and not the drain plug in the livewell.  There is no way it would drain that fast (if it would even drain at all) manually if you weren't running the boat up on plane.
