Impeller rattle when flushing motor

[mnerren]

I just bought an 08 Ultra 250X and had a question about a rattle from the impeller when flushing the motor out with a hose out of the water. Is this a normal characteristic due to the impeller being out of the water and under no load? It seems to have done this from day one, I have about 12 hours on the motor now, was just doing my first oil change and 10 hour service and thought I need to find out just in case this is not normal. Thanks, I did a search and found something on this but not in the Kawasaki section.

its normal, just dont rev it too much, a couple of times to clear the water box is ok.
