Is an impeller the same as a water pump?
Yes. In laymens terms, the impeller is the rubber thingamajig inside the water pump that moves the water. The water pump is the complete assembly. Unless the gaskets, O-rings, etc are broken or the housing is damaged, you can usually just replace the impeller.
Why do impellers fail?
Abrasive sandlike material can cause the impeller to wear out faster. Impellers can also wear out by becoming stiff and brittle due to the motor sitting unused for several seasons or being exposed to heat. Water lubricates the impeller, and if it’s run dry, the impeller can be ruined in a few seconds.
How long can you run a boat motor without water?
between 2 and 10 seconds
How do I know if I need to replace my impeller?
The Outboard Motor Overheats When the impeller needs to be replaced, the motor’s internal temperature rises and the equipment stops taking in cooler water and pumping out warm water. This will eventually lead to overheating, which can leave visible scorch marks on the motor.

It happens because driving without a thermostat tricks your engine into thinking it is cold outside, causing it to adjust the gas mixing valve and push more fuel to the engine.
Should I change thermostat when changing water pump?
Most of the time, RRT will recommend replacing the thermostat at the same time as the water pump. In almost every case, the thermostat is located adjacent to the water pump and needs to be removed to access it. This saves you labor as you usually only would need to purchase the part during this job.

What causes water pump failure?
Water pumps can fail prematurely due to corrosion inside the cooling system or from an imbalanced water-pump shaft. If there’s a mechanical fan mounted on the water-pump shaft, vibrations are the result of a bent fan blade, which can lead to the shaft cracking or breaking. A bent pulley also can cause the same damage.
How do you troubleshoot a water pump?
