I had a problem like that and ended up removing the strut and putting it back in the right orientation, so the prop shaft was lined up with the shaft log. Very ugly job. Part of an even bigger, uglier job. There was no sign the strut had been bent, it was nicely bedded to the hull, it was just pointing about an inch high, apparently from the factory.
