They are quite simple to make, and relatively cheap ~ $30-$60
depends on how fancy you want to get. **Note your kayak needs
to have a tankwell...
Here is a Nemo Tank™, my friend Grego designed and made
for me.
What you need:
1. A 5 gallon bucket (or any plastic container)
2. Atwood 500 bilge pump about $17 at Walmart, or a boating store.
Here is how it connects to the bucket...
...and the connector piece on the inside of the bucket (comes
with atwood pump)
Inside bucket view...
3. A piece of pipe to attached to the Atwood pump. Notice there
is a connector piece, any 50 cent plumbing connector works, this
one is supposed to hold your prime if you turn your bait tank
off. My friends just use a cheap connector which work fine.
In this picture, you can see that the pipe goes down into a scupper
hole. You need to cut it so that it is flush with the bottom
of your kayak, or even a little higher, as water is pushed into
the scupper holes with your weight, water in tank, and your equipment.
4. Drain plug from a plastic water container, it pops right out
when you are done drinking all the water. Notice the drain plug
was aligned with the other scupper hole. I used Marine Goop to
hold it into place.

5. Get a 6v battery, unless you are one of those guys that hooks
up your GPS, and color FF to the same battery as your bait tank,
then a 12v. I prefer a seperate 6v battery as they seem to kick
out less water, which is less stress on the baits. Besides a
FF/gps/bait tank on one battery doesn't last very long.
Check out www.kayakfishinggear.com for
great prices on batteries and floating chargers. They support
many kayak fishing events, and have quick and friendly service.
6. A battery box, I have a Pelican Box attached to my 5 gallon
bucket to hold my battery. You can rig a switch to turn it on
and off, or just hook up the battery directly.
Or some people just use a tupperware style plastic box. You can
also use a dry bag, this is what I use for my Fish Finder battery.
You can also run the wires into their kayak hull, and store the
battery box there. Again, depends on how fancy you want to get.
7. Rod holders, you can use 2" PVC, or in all honesty better
yet pre-made rod holders, any boating store has them. Attach
to the back of your tank.
8. Drainage holes.... I placed mine in the back off my bucket,
some people have another tube going into the water opposite side
of the bilge pump.
9. Straps, you can just use bungees, what ever is easiest to
hold your tank secure. In this pic, they are not cinched, but
you definately want to cinch them down. Notice they are attached
to the padeyes, again, you can use bungees or rope.
10. Bait...
Now put it all together.
The final Product in my kayak...
Priming your Pump
One other note, you need to prime your pump. Very easy, turn
on your pump, or plug in battery if no switch, unscrew the Atwood
500 pump from the bait tank, (which is obviously still connected
to the pipe, via the connector)
then pump up and down through the scupperhole, water should come
shooting out, leave running, screw back onto bait bucket. Some
people use a priming bulb
(which would replace the plastic connector that attach plactic
pipe to your atwood pump), you squeeze to prime, again found
at Boating stores etc.
Done you say? Nope...
There is another style pump... that hangs over the side of you
kayak in the water... It is much more quiet, but not as flush
as the Atwood 500... Again found at boating stores, maybe Walmart.
It is made by Atwood called the Tsunami. It is submersible, and
hangs over the side of your kayak in the water.
You can modify your 5 gallon bucket or plastic container to use
this pump, no priming involved, just turn it on, and drop over
the side of your kayak.
I have a pre-fabricated Thresher tank by www.liquidfishing.com these
are top notch tanks.
Here is a view of the tank in my kayak, as you can see the tube
that runs to the Tsunami pump is tucked in my tank well, but
once I am in the water, I throw it over the side. This is handy
for bass tourneys when you are not running your pump all the
time, and don't want any drag.
A water shot, you can make out the tube that is attached to the
Tsunami pump submerged under water.
Again, this pump can be used in place of the Atwood 500 bilge
pump.
