Not pumping water.

Just replaced the impeller on my OB, reassembled and guess what.
This is my first impeller change so bear with me.
When I fitted the impeller I noticed that it was not tight on the drive shaft and if I turn the drive shaft by hand the impeller does not move.
The impeller is identical to the one removed.
There is a grove on the impeller and the drive shaft so I wonder if these should line up or if I'm missing a part.
Any help greatly appreciated.

there should be a small metal tab that fits in the notch of the shaft and the water pump, making the pump rotate.

Ok, new questions. Where can I get a metal tab thing. (as said I'm a novice)

You can reuse the existing key, maybe its on the floor of your workshop? Its a very small half circle shaped piece of stainless.

Part number is 300611 according to this: http://www.sterndrive.info/outboardmotor/id10.html

But on here: http://www.tmp-johnson-evinrude.co.uk/waterpumps.html - the part number related to something else

I think the existing key is lost. It's for a mercury 9.9 not a Johnson.
Thanks for the help.
Any dealers on here help with getting one of these?
