How often should you change impeller on Mercury outboard?
How Often Should You Change the Water Pump On Mercury Outboard? In most cases, you won’t need to replace the water pump unless the housing is damaged. Instead, replacing the water pump impeller every three years or sooner should avoid most water-pump-related issues and keep your outboard running in excellent condition.
What causes an impeller to go bad?
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.
Why is my impeller not working?
Blockages are one of the most common causes of impellers not spinning. So, it is a good idea to check that there are no debris, such as weeds, preventing from spinning it.
