I painted fluorescent yellow lines that appear on the top and bottom of
the prop shaft when the prop is aligned with the slot in the
keel/rudder (so it's relatively easy to do a visual check into the
engine compartment that the prop is aligned).

I heard tell once that with an A4, putting the transmission into
reverse, and then gradually shifting it into forward while the boat is
moving forward will get the prop aligned and locked in the right
alignment.

When I've tried this in the past, the yellow paint lines have generally
been in the right spot if/when I've checked, so I'm incluned to say that
it works.

Cheers,
