If it has the old style impeller it could be worn brake shoes. Another thing to try is to take the bush bearing out and spin it it half way(180 degress) around and reinsert it.

new style impeller

I would try the bush bearing, it is seated around the top of the hole the impeller sits in

Did you recently replace the drive unit or is this the original one the pump came with? I ask, because if you changed it and did not change every part that came with the new one there may be a mismatch. In rare cases and older pump will run noisier with the 6100.70 than it did with the older 6100.60 because the 6100.60 has more articulation points to absorb irregularities in the rotor well and propeller movement.
