SEI 206 Lower Unit Prop Rubbing Housing

[lv1975]

I just received my new lower unit on Friday evening. It is going on a 1996 Mercury 175 EFI and running a Quicksilver Laser II prop. I installed the lower unit on Saturday and noticed that the prop was rubbing the housing. It is rubbing on the outer edge of the housing and on the retainer holding the carrier assembly. I did install my thrust washer. I did not notice any damage on the shaft or on the thrust washer. I did not have any problems on my old lower unit. Any suggestions?

I stopped by the local marine shop and they informed me that they do make different thrust washers. I was able to obtain a thicker washer to give the prop the proper spacing.
