175 hp Lower unit Mercury

[rmd8123]

I just started working on this motor, hooked the ears upto it, and no water coming out of the whole. So i tore it down, replaced the impeller, put it back together, and only getting a little sputtering coming out of the hole, but it seems like water is still being pumped upward into the motor. I Believe i have the water tube lined up into the water pump. Anyone have any ideas? thanks

Well i pulled off the pump houseing and looked at my new impeller, and there was two small chunks out of two fins. What would have caused this and could this be why its not pumping well?

1- What would have caused this and
2- could this be why its not pumping well?

1- engine run "dry", impeller installed backward, damaged housing...
2- yes

I replaced the impeller again and put it all back together, put it in a barrel and after about 1 minute it starts spitting water out of the hole, not really strong, but not sure how much should come out at idle... any ideas?
