The impeller pump on a motor vehicle is more commonly know as the water pump. The water pump, pumps water through your cooling system to keep your vehicle from running hot.
Propeller is external (outboard motor on a boat) Impeller is internal (vehicle water pump).
Synthetic Rubber
No power to pump. Motor burned out. Intake is clogged. Impeller disconnected from motor.
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)
I had a look to se if I could find a craster pool pump and had no luck however the impeller on every pool pump I have ever seen is in the impeller housing which is bolted straight against the motor.
An impeller in a pump is the part that the motor spins that actually does the work of moving the water. Due to it's design when it spins it creates a vacuum that pulls the water in the middle of an opening on the front of the impeller and throws it to the outside where it is then channeled to the output of the pump.

impeller use in a pump casing .
The centrifugal pump works in the same way as you use the straw. As the engine starts, the impeller turns which forces the water around it out of the pump's discharge port. ... When the water hits the rotating impeller, energy of the impeller is transferred to the water, forcing the water out (centrifugal force).
The water pump impeller on a 7.5 hp Mercury outboard, is located on top of the gearcase, and is driven by the driveshaft.
Possibly the impeller needs cleaning or a blockage in the line
First, remove the lower unit (there is a housing for the water pump). The drive shaft goes through the housing and turns impeller. Remove the housing, the impeller is on the shaft. Install the new impeller. When replacing the housing, turn the drive shaft clockwise to make it slide down over the impeller.
