  You need a scoop below the hull if the intake in facing aft on the transom, since water is being pulled away from the pump when the boat is moving forward. However you probably have another problem since you should have good flow when the boat is not moving.
  
  Possible problems to check out:
  
  A kink in the hose between the pump and live well.
  
  The pump's impeller could be spinning in the wrong direction, The blades on the impeller are curved and move more water with the curve facing the direction of travel. To reverse the direction of the impeller just switch the wires around.
  
  The pump might not be getting enough juice due to corrosion in a wire connection. check all connections for green corrosion.

  Thanks. The pump itself is working fine now at idle. I forgot to mention that anytime we run it stops working hen to make it start again I have to manually take the top of the pump offhand out it back on. No clue why. When you say a scoop what do you mean?

  What your experiencing is called air lock. the intake is out of the water on plane an allows air to get sucked into the pump. Since its a centrifical pump it pushes water, it doesn't pull water with a vacuum. T-H marine makes a couple scoops that will keep positive water pressure around the intake while on plane and should eliminate the need to pull the pump to prime the impellar.

  This is a hi speed pickup that gets mounted thru the hull bottom.
  The T-h scoop mounts around the flange of the thru hull on the transom an extends slightly below the bottom of the transom to scoop water. The TH scoop will not require any new holes or repair of old ones.
