How do I know if my pump impeller is bad?
Signs of a bad boat impeller are either boat engine overheats when you try to accelerate, loss in impeller vanes flexibility, physical wear & tear like cracks in impeller vane roots, melted or worn of vanes. Even if you see less or no water coming out of tell-tale, it might be due to a bad impeller.

How do you change a raw water pump impeller?

What does an impeller do on a pump?
An impeller is a rotating iron or steel disc with vanes in a centrifugal pump. Impellers transfer energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid radially outwards from the centre of rotation.
How do you troubleshoot a water pump?
Water Well Pump Troubleshooting
- Record start pressure of pump.
- TURN POWER OFF.
- Drain water from tank by opening valve or faucet, leave it open.
- With tire gauge check air pressure. Air pressure should be 2 lbs.
- If start pressure is unknown add air to 25 lbs.
- If tank will not hold air – CALL FOR SERVICE.

Can you put a water pump impeller backwards?
When an impeller is running backward, the centrifugal forces will still accelerate the water—although far less efficiently. If the impeller is threaded to the shaft, it may unscrew when running backwards. This however will break the impeller if you turn the pump while it is spinning backwards.
What happens if you put an impeller in backwards?
What are the three types of impeller?
