How do you repair a impeller on 7.5 sears outboard motor?

To repair the impeller on a 7.5 HP Sears outboard motor, first, remove the lower unit by unscrewing the bolts that secure it. Once detached, take out the old impeller from the water pump housing, noting its orientation for proper installation of the new one. Clean the housing, install the new impeller, ensuring it fits snugly, and reassemble the lower unit, making sure all bolts are securely tightened. Finally, test the motor in water to confirm proper operation and cooling.
