Bait pump placement

[asystole]

OK so I've searched the forum and read many of the bait tank posting and looked at a lot of pictures. I am in the middle of my build on a bait tank/live well and would like some opinions on pump placement.

I am using the large pet food container and next step is the plumbing.

I have a '08 Tarpon 160i and have considered these 3 options:

1. Mounting a bilge pump on the intake hose and let it drag in the water over the side of the boat. (Least desirable)

2. Through hull mounting (Like Grego did)

3. Mounting pump in tank, pick up through scupper (Like the Hobie)

4. Making a bracket to mount pump on rudder mount on back of boat.

I like the idea of mounting it through hull but hate the idea of drilling a hole in the bottom of my boat. I also liked the idea of mounting it on the rudder mounts, but have not seen that and wondered if it might be a problem since it is so far back and would be a hassle to get to in the event it plugs up.

Let me hear your opinions on pros and cons because this is my first fishing kayak and I don't have one.
