i just replaced the impeller and i put it in a tank of water and started it. i didnt see any water being pushed back out when it was running. i only ran it for maybe a 45 sec and shut it off. i really need to know if this is working or not, i dont want to go out and overheat my motor, how can i really find out without wreaking other parts.

Run it on muffs, then you can see the water flow
