HELP Water Pump IMPELLER Question

[BayouNola]

HELP I just changed the Impella on my 1994 150HPYamaha. Is this normal or not. As soon as the engine started up I did not have any water peeing out Now out of caution I turned it off. I did not let it run more then 5 or 10 seconds. Is this normal or should I let it run a bit longer to see if it will come out. The only thing that should be noted was when I replace the Impella with the new one. I had to use the old housing and the old stainless steel cup instead of the new one. The reason was the new stainless cup would not fit or lock into the old housing. On top the new cup was 2 raised tips and the old had just 1. So it would go back correctly I used the old cup. Do I have anything to worry about or did the Impella go on backwards??? Help

it takes a few seconds but GO back.
get the CORRECT parts and assemble it again.
there were a few models, way back, that the 61a-w0078-03 kit required the new 61a housing.

don't be a victim of a self inflected wound.
