Installing the
Stuffing
‘Ihbe
1. Inspect
Location:
Prior to drilling or cutting from the outside of the hull, the interior of the
hull should be inspected to ensure that there is proper clearance for the
stufting
tube and that there are no cables or stakes to impede the cutting or
drilling. The stuffing tube is 150 mm
(6”)
in length and, depending on the
thickness of the hull, will require at least
200
mm
(8”)
of clearance to
facilitate routing of the cable.
2. Drill the Hole:
Drill or cut (with a cutting torch) a 38 mm (1
l/2”)
hole in the hull for
installation of the
stuffing
tube. A fire watch should be stationed inside the
hull.
3. Install the
‘Abbe:
Remove the packing nut, compression bushing, and washers from the
stuffing tube. These will be necessary at a later time to seal the stuffing
tube, after the transducer cable is fed up into the hull. Insert the
stufling
tube into the hull and weld the stuffing tube in place (See Figure).
