To replace the impeller on a 35hp Mercury outboard motor, first, ensure the engine is off and disconnect the battery. Remove the lower unit by unscrewing the bolts and disconnecting the shift linkage. Take out the old impeller from the water pump housing, clean the area, and then install the new impeller, ensuring it is oriented correctly. Reassemble the lower unit and reconnect the battery before testing the motor.

you feel the clown
You don't wire anything. the water pump is mechanical , consisting of a rubber impeller /impeller housing and copper tube running from the impeller housing to the engine block. The drive shaft runs from the gearcase through the impeller/impeller housing to the engine block allowing the intake of water to match the engine RPMs. if the water pump does not work it is most likely that the rubber fins broke off (extremely common for all outboards that are water cooled)
right behind the prop, on the same shaft
What year? It may require special tools.
