I changed my impeller and when I started my motor I had no water comming out out of the tell tale. I took the lower unit apart to find my impeller iin pieces so I reinstalled the old unit and once again had no water comming out. I am under the assumption that my cooling system is plugged up is there anyway to check this? It is a fresh water motor. I tried bowing air through the flush port and it is not letting me. does anyone have any suggestions?
You have us concerned when you said you installed a new impeller and it immediately broke into pieces. Something must have been installed wrong or the motor was run dry, such as using a flush muff and not taping off the bleed holes under the anti-ventilation plate.
Was the impeller melted looking? If so, you need a whole water pump kit and also you may have to remove the powerhead to check for melted exhaust parts, charred gaskets, and for any rubber bits that may have lodged in the passageways.
Please obtain the correct factory service manual to guide you.
