    Pitting on Impeller

    Was looking and saw that the impeller on my 01 gp1200r had a little pitting on the outer edge in the middle of the fins that is about 2 inches long. It is kinda a dull gray in color. What would cause this and what ill effects would it have on performance?

    Could some of the cavitation have come from the packing that goes between the transom and pump shoe falling out?

    That's a result of cavitation. Need to find the cause. Air leakage, etc....
    If not rectified, it will compound.

    Impeller housing


    Gap between impeller and housing.
