The water pump impeller on a 7.5 hp Mercury outboard, is located on top of the gearcase, and is driven by the driveshaft.
The impeller on a 9.8 Mercury outboard boat motor can be easily changed. Remove the retaining bolt. The impeller will come off. Reverse the process to install the new impeller.
The impeller is located inside the water pump housing, on the topside of the gearcase. The gearcase will have to be removed in order to service it.
The impeller is located in the lower section of the motor near the prop. Take the two nuts off and the lower unit will separate from the top. Remove the O ring and the seal from the long shaft before removing the two nuts from the water pump housing. Good luck removing the impeller itself. I had to cut the soft brass ring with an oscillating tool. A paint can opener also helped in the removal.
the impeller are the fan blades themselves.

I contacted Mercury Marine outboard division and they answered within a week. Very good response.
