Customer reply replied 3 years ago
it is a Suzuki Genuine Part bought a parts dept from a local dealer. impeller looks good but the inside where shaft goes looks real shiney even blueish
Marine Mechanic: Jeff G., Marine Mechanic replied 3 years ago
The inside of the impeller itself looks bluish? Did you replace the impeller key when changing the impeller? If you have the proper impeller and key then it has to index on the driveshaft and can not move on the driveshaft. If the key is worn or missing then the impeller can turn on the driveshaft.Make sure the key is in place.
