1972 9.8. I'm not getting any water from pee tube. In fact seems as if exhaust is coming from the tube. Have changed the impeller and using a drill to turn driveshaft, the pump works fine in a buckeet of water. Blowing air back through the tube, I can hear air in lower leg but it isnt coming through the cooling tube. Can there be a leak between water jacket and exhaust passages some where? Appreciate any help or ideas
