   Has 12 hours on her and it makes a screeching noise almost like the belts on old cars. It doesn't do it all the time just once In a while at idle speed. Took it in for a check up and they claim it's fine. Mercury also claims it happens on 40-70 non big foot models. Anyone know anything about this?

   My reading turns up a bushing at the upper end of the driveshaft
   where it passes through the exhaust adapter plate.
   Driveshaft rubs on the bushing making the squeal at low rpms.
   Supposed to be barely visible through a hole in the exhaust housing
   when the engine is tilted all the way up and rotated to one side.
   Spraying silicon lube onto the shaft and bushing is supposed to kill the noise.
