My Sawzall got submerged by Katrina. When I tried it out it made a faint
buzzing sound, as if trying to move, but didn't move at all. Is it worth
repairing, and if so, what are some likely areas to check? (It was
working perfectly previously.)

Good chance it is gunked up with mud or silt and maybe corroded a bit.
Probably bearings are either damaged, or will be damaged by anything in it.
I'd take it apart, clean it, replace bearings and give it a try.
If you are talking about a genuine Milwaukee Sawzall, it is worth fixing. If
it is a $29 copy cat recip saw, just toss it.
I've spent several hours and about thirty bucks on my Unisaw motor.
Pulled it apart, flushed it, baked the field and rotor in an oven for
six hours at 150F, replaced the bearings, capacitors, cleaned the
centrifigul switch. Put it all back together and no go. pulls enough
amperage to pop the breaker in about 5 seconds.
Also have a contractor saw, stock feeder, lathe motor, several
thousand sheets of sand paper, and a bunch of other supplies that were
submerged with the Unisaw. I think most of it is toast. Uninsured
In your case I would pull the brushes and make sure they are free and
connected and that the commutator is clean as a first step.
Are you going to try a rebuilder? What you said you did sounds about right
but perhaps you missed something. We had a flood at work and took 18 motors
(ranging from 3 hp to 75 hp) to a repair shop. Most took two days and every
one works as good as new.
Yes, I could have missed something. There are two in town, one is a
Marathon authorized repair center. However, the Delta induction motor
guy, (I used to work for Delta, he used to work for me, so I called
him direct) thinks the field is open, would require a rewind and might
cost more than a new motor. But I'll give it a shot, nothing
ventured, nothing gained. This was a brand new Unisaw, had never been
used. I took the rest of the saw apart and recovered it piece by
piece. Down to the motor and the mag starter that are no good. (BTW,
before you ask, I tried the motor with a known good starter)
