I have a had a 1990 Champion bass boat for a few years now. I leave the boat in the water just about all summer long, however I will use the live well and the only way to empty the live well is to open up the valve and let it drain out while driving down the river. This does not work all the time and also takes a long time for the water to drain. I have been just using a spare bilge pump and a hose connected to it to empty the boat while it is in the water.

My question is there a way to have it so I don't have to carry around a pump with me on the water, so I could hook something up to my dash just like my bilge for the boat? 

It sounds like you either need to replace your livewell valve so it works as intended, or you need to add a pump-out kit. If your livewell has a normal spray head that can be used on recirculating, they're easy to install. I'd be guessing your boat does, but you'd have to check for sure. It also needs to have a recirculating mode, given the boat it should have. If not you'd need to add another pump but it'd still be pretty simple.
