Let's say for instance the live well on your bass boat is broken and you just boarded the door shut and put carpet over it because it would've been serious time, money, and trouble to fix it. Is there such thing as an external live well like you would put elsewhere on the boat? Like a cooler size one with hoses and connect to the battery?

Any Cabelas, BPS, Walmart ect. sells aerators systems that allow you to convert coolers into live wells. I use one on my little tin boat.

A cooler with a air pump

That's it? So basically I can convert a big rectangular plastic bin into a home made live well with an aerator?

Yes, that is all a boat livewell is with a drain.

Cool. :-)

But, get mater from that lake and make sure it stays cool. Put ice cubes in it to keep the fish alive.

I use a 120 quart cooler with a bilge pump feeding a spray bar in the top.  I use an aquarium thermometer to control the temp and do my best to match the lake.

I use those little pool ones whenever they get 4 degrees over I change the water. It's quite a challenge with a 5 fish limit though. Especially when you forget to put cull buoys on.

If you're going to do it I wouldn't seal your livewell up though. That would be a ton of space to waste that you could be using for storage instead. 

The money you spend on a big enough cooler, aerator, etc... Couldn't you just fix the old live well?

You have a boat without a livewell.

He said he has a live well, it's just not working properly.

He has this boat but has to keep top secret uranium materials in his live well. Better ?

I'm so confused what this has to do with the OP's question or with Scrogg's comment??
