    Looks like a stress crack, not like you hit anything. Sorry to see.

    yaa all of 12 veins have cracked on me not just 3 or 4

    i sent the pics to riva , and they told me they will change the pump for me

    but im afraid it will happen to the new pump that they will send me

    It just looks like two abrasion marks on the second photos! And two similar on the third.. Almost Lke scuffs, I see some marks on the impeller as well, looks like something rubbed against it. Just posting what I see. I know cameras can add things that you can't see with the naked eye and remove things that are clearly visible on shiny surfaces, maybe it's just hard to see. . I agree tho, they sure are stress cracks . My first thought was " damn that motta has got a lotta powa"

    Damn, that sucks. Maybe they can warranty it for you? How are they made? Are they cast aluminum or stainless steel? Been a while since I have seen one. Maybe it was a bad casting?

    It's odd that it cracked on the inside where the hub is rather than on the outside where all the stock pumps break with higher horsepower.

    UPDATE - I see they are stainless steel, but still looks like they may be made from a mold? I am no engineer, just going by what I am looking at from your pics.
