Speaking of thrust however, this is a good time to check that your
shaft is firmly locked into the coupler with shaft indentations and
safety wire on the set screws. More than one boater has had the
experience of reverse thrust taking the shaft out of the boat. You'll
want plenty of reverse thrust to properly set that new anchor of
yours.


Good thinking.

When we had the shaft shortened, we did it from the coupling end so as to
make it simplest (no taper, threads, etc.).

Previously, and, now, this time, once we'd gotten the
less-than-.001-undersized shaft in the coupling and keyed (new keyway, of
course, the bulk of the prior having been cut off), the hole in our coupling
which took the square-head bolt was used to center-dimple the shaft, then a
vee drilled out to accept the bullet-nose of that bolt (with the coupling
removed, of course).

When I put it in, I used Loctite Blue, and then safety wired it. The other
two security mechanisms are very stout, Loctite'd and lock washer'd hardened
7/16" bolts squeezing slots.

I think we're probably ok :{))
