Re: 20 sf bait tank ?
 

The vertical pvc tube with the 90° elbow at the bottom is plugged into the drain hole. When the tube is in place, water only drains out if it's above the top of the tube. The tube is a bait well accessory I bought off the shelf at a local marine store.

Im getting aroung to this fix now Dave where did you install the control; valve for incomming water that you can access it?

It's located in the starboard transom storage box.

In my 1st 20 I had a differnt setup

I had a leaning post that I could fit a kodiak well that I plumbed thru the floor.

under the floor I had the raw water pickup connected to the bait pump that went under the floor and came up next to the well. There I used a gas fill that I installed in the floor and then made a connection to the "intake" of the well. I also installed a 2nd gas gass fill on the discharge side and had a connection to the gas fill and from there it ran under the floor to the transom and out from there

It worked really well and the nice thing was that the days I was not fishing I could disconnect the tank screw in the gas fill covers and replace it all with a cooler for drinks and stuff.I dont have any pics on hand put I liked the setup and it worked real well.

My MA has a built in livewell in the corner transom biy from the looks of it is way to small for any off shore fishing and I may copy it againe

Thanks

Dave, I'm not quite sure I understand what you are saying here or how your set up works but if the vertical tube ( which I assume you disconnect from the elbow when you want to drain the bait well ) somehow gets loose/disconnected while the boat is @ rest & the float switch/pump for the bait well fails, would'nt that potentially sink the boat ?
Also, when the boat is @ rest & you are filling the bait well through the drain/vertical tube , does the water eventually stop flowing in when it reaches a certain level somehow or do you have a shut off connected to the vertical tube like you have on the clam shell tube?

If the boat is empty at the dock, the water in the well rises to just below the deck. If the boat is loaded with gear and crew, and the pump is off, you get wet feet in the back of the boat. Since the deck is sealed, the overflow doesn't go into the bilge.


No shut off. If I want to stop the water coming in, I pull the tube and replace it with a plug.

the easiest would be to put an intake shutoff inside the well for easy access that would come from high speed clam shell. I never had one set up like this , I always pumped in and the drain was out the transom, it would overflow some if everybody went to the back but I'm in Fla. I like the idea of pumping out as the pump pumped the water out it would seek its own level and draw freshwater from outside at the same rate.

the above floor well under a leaning post is the best setup but is a good deal more money to set up
