I put the UAT all the way up frount on a jet I had that need nose weight, It work great. The UAT is 8OZ of weight that you can use anywere. Mine was about 30 inches in front of the motor. I had the pump right next to the motor. Never had a problem with the engine. Don't move the pump move the UAT, more weight.
