Oh my God, the prop!!

Funny you should mention that. It could, actually, *be* the prop -- but to
my ear it sounds more like a very slight engine roughness rather than a prop
imbalance.

Sometimes it's hard to separate the two -- and sounds have a funny way of
traveling.

For example, our Subaru Outback has developed a very annoying rattle in the
right rear that starts at around 50 mph. It's a harmonic rattle, and we've
looked at EVERYTHING trying to find something loose, to no avail. Yet,
clearly, there is something very loose, somewhere. Our best guess at this
point is that it's something inside the right rear door -- but I haven't had
time to rip it apart to see.
