OK, I have some problems with my water pump on my merc 500 50hp. I have just changed the water pump impeller and the whole housing because everything was really shot, and when I hook up a water flusher to the engine it doesnt pump water out of the tattle tale hole, someone told me that the line could be plugged from pieces of the impeller going into the water tube and sure enough it was so I changed the water outlet that goes to the powerhead and to the tattle tale hole and it still doesnt come out I tried putting a hose to the line that goes to the tattle tale hole and water comes out but not out of the water tube that goes to the pump, is there any way somebody can point me in the right direction. Thanks
