20 sf bait tank ?
 

My 1982 20' sf has a bait tank I. The rear floor. There was the remains if a airiator In there the kind that sprays water to make bubbles.
And on the transome above the hull drain there is a fitting with a plug in it.seen here

on the starboard side next to the bildge pump exit is a capped off through hull
I'm wondering how theese were set up was thus capped hole a drain hole?
Ever tank I've had you turned it on the tank filled and ocerlowed out a drain hole I cat see how this could work or take in water while running

BatWHat did it just recifculate the water and make bubbles ? Not fresh water continuasly ?

Re: 20 sf bait tank ?
 

I've got mine set up to pump water out of the bait well. Water comes in through the transom drain. Pump is controlled by a float switch mounted inside a home made aluminum housing to keep the bait from getting stuck under the float.

Hanks for the pic.
Can you explain furthur You pump water out doese it pump n or just floe in from transome hole. Doese it flow in and out ?
I've had tanks that circulated in and out continusly I dint see how this could without a new throughthull

Re: 20 sf bait tank ?
 

The in floor wells work better to have the pump pumping water out of the well. That eliminates the worry of the drain - they always come in easy getting it out is harder LOL

Having a flow control on the thru hull will allow for you to control the water height to keep it from overflowing easier

Re: 20 sf bait tank ?
 

The vertical tube is plugged into the hole that goes out the transom. When anchored or drifting, water comes in through the tube and fills the well. The float switch cycles the pump on and off to maintain the water level. When I want to drain the well, I pull out the tube when the boat is on plane or on the trailer.

The hole to the port side of the tube is connected to a clamshell through hull pickup. There's a pvc ball valve in the line that I use to control how much water flows into the well while the boat is on plane. As water comes into the well on plane, it overflows through the vertical tube and out the transom. If water is flowing in faster than it can flow out through the vertical tube, the float switch will activate the pump.

O blue heron I understand thebwater enter from a clamshell but if your anchored do you meen you have no flow and the water enter from the transome drain hole ?
Perhaps that why on mine someone had a airator pump

Re: 20 sf bait tank ?
 

so Egg not having a clamshell as blue heron just the transome hole the the capped off hole next to my bildge exit how would you plumb it please?

Re: 20 sf bait tank ?
 

At rest, the waterline as just above the deck. The pump keeps the water level about 3" below the deck. Even with only 3" of hydrostatic head, the water flows in through the transom pretty well. And you don't really need water flow when you're on plane. The water sloshes around enough to aerate it.

Re: 20 sf bait tank ?
 

So what do you do Dave while on plane with bait in the tank do you have a valve so the water dosent drain out the transome hole were it comes in?

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
