There needs to be a key.Take it apart again and find the old key (it may be a wedge).the impeller won't turn without it.

Re: help with water pump

The key should have been included in the kit. It is called the Impeller Key and is OMC part number 0331107. There is a slot in the shaft that it fits into and the impeller is slid down onto the shaft.....

Re: help with water pump

I like to always buy the complete kit (i dont think it is that much more) whenever I replace the waterpump. I like to replace the o-rings etc on the housing, and I figure as long as I have the thing apart I may as well replace the impeller cup.
