My son is having issues with this Yamaha 4 stroke motor. Replaced impeller 3 times in the last 3 months. Install new one, go fish, impeller shreds. repeat the process and it shreds again. He is in FL so I suggested finding a dealer to check the housing and low water pick up screens as he may be sucking sand and gravel that is shredding it. Any other ideas?

-Make sure it is the correct part
-make sure he has the veins the correct direction
-no obstructions in the housing?
-key installed, although that shouldn't shred it.

Check for the correct part number from a different source. The same guy is going to give you the same answer. Verify installation is done correctly via parts manual or Youtube. Try testing in a controlled environment like a trash can filled with water. Run it low speed for 10 minutes and then take it apart again to see if it is still shredding.
