Looks like its OK (hard to see as its pretty dark in the pic)...might be worth a tweak to make sure its fully off to the right.
Other than that you are into understanding why a prop has sideways twist/effect to see if there is something else going on ....
I had the same handling until I bothered to look at my tab which was set directly straight - 20 sec later after an adjust and it runs nice and straight hands off . There will never be a perfect setting as the need for the 'correction' will change with engine trim/ angle of approach to the oncoming water and speed etc ...but only slightly if its set up mostly right.
