I changed the impeller back in July and the tale tell is not spraying properly. Please see the video below and let me know what needs to be done to correct the problem. The tale tell sprays good and strong on start up but weakens as the motor warms up. Copy and paste link to see video.

Your UTube link does not seem to work. The dot between tu and be may be the problem.

Why did you change your impeller back in July? Was it to correct a problem similar to your present one?

I changed the impeller because my old lower unit had corrosion so i purchased another lower unit and changed the impeller. I inherited the boat which is a 2007 carolina skiff with very low hours on it and the boat has never had any problems. the new link is below.

Did the old lower unit pump water OK- did you first notice the problem after you changed the lower unit and the impeller? If that's the case, then it suggests that your problem is somehow associated with the new lower unit. Are you sure that you changed out the impeller properly? There might also be a crack in the lower unit housing somewhere that opens up as the temperature comes up.
