Hi Gary,

I don't know if anyone suggested this yet (I don't
read all the mail), but it might be your propeller
shafts. They have a couple of things that get loose
and could be causing the chatter. We had a prop strut
with bad bearings or the u joint (I don't remember,
Billy took care of it), but we had a similar chatter.
