I simply used a container with a $39.00 battery operated air pump in it. Worked am absolute treat. Very calm fish.

Tonto I will try takes some pictures of my setup tomorrow. Starts with a scoop mounted on a bracket just below the hull line, creates just enough flow when on the plane without blowing the fish away. I mounted a 500gph rule bilge pump on top of the bracket with a hole in the bottom of the pump bracket. This allows the water to go straight up through the bilge pump even when its not running. I then ran a pipe with a one way valve from the bilge pump up to my livebait tank which is a 40l round chlorine bucket mounted on the transom. I installed a cutoff tap where it goes into the tank. I keep it turned off when motoring around to prevent the tank filling. Once it goes into the tank I have a hose connection mounted on the inside. I have a length of hose with a fitting which I clip onto the tank to wash down the boat at sea. I have had 20 Jacks in the tank all day no worries. With the scoop you get a constant supply of fresh water which is the key to keeping livies alive. When I stop an anchor I have the bilge pump set up on a time which goes for 30 seconds every 3 minutes. Have run it all day and it doesn't flatten the battery. 

look forward to the pics

I've had no need for one on the intake, however I have fitted one to the outlet, as lazy fish seem to get stuck to it, and stop the flow!

the T piece you have at the bottom end will restrict the flow to the left if you have water coming in from the bottom if you want an even flow fit a Y piece but make sure you fit it the correct way otherwise it restricts the flow to the one side the photo will show you how to fit it if you decide to fit one with a Y piece if you do not connect it the way it should be connected it restricts the flow out on one end too .in other words if you connect the incoming flow to one of the Y,s & epect the flow to go out at the other end of the Y & the remaining end this does not work the flow presure is not great at the outgoing  Y end but stronger on the other end

brainwave....if I now want to keep bait alive whilst boat is on the trailer

Also I have a live well pump as opposed to a bilge pump which allows a wash down hose to be used but these are normally fitted inside the hull. Good ideas there cheers tonto  I'm going to take that "Y" and make it a "T". Buteline plumbing fittings are the go I reacon, luckily I've got the clamping tools for these too,otherwise any old marine adhesive would suffice I'm sure.  Hopefully that'll feed the pump sufficiently underway, might need to install a value to the "T" outlet if pressures aint enough. Installation tomorrow.
