Installing the Transducer in a Fiberglass Hull
When installing the transducer in a cored fiberglass hull, you must cut the fairing block
page 4) and seal the exposed areas of the inner core with marine-grade fiberglass epoxy resin and allow it to
cure before installing the transducer
It is recommended that two installers complete these instructions, with one positioned outside the boat and one
inside the boat.
You must apply marine sealant where necessary to prevent seepage and corrosion

1 Push the transducer cable and stem
2 Secure the M12 nut
between the M12 nut and the bottom of the fairing block.
3 Insert the anti-rotation bolt into the bottom half of the cut fairing block.
4 Apply marine sealant to the surface of the bottom half of the fairing block where it contacts the hull.
5 From outside the hull, push the transducer cable, stem, and anti-rotation bolt through the mounting holes in
the hull, and push the bottom half of the fairing block firmly against the outside hull.
The fairing block and transducer must be parallel to the keel. The arrows on the fairing block and transducer
must point to the front of the vessel so the transducer aligns with the vessel heading.
6 From inside the hull, pull the transducer cable, stem, and anti-rotation bolt through the top half of the fairing
block.
7 Apply marine sealant to the surface of the top half of the fairing block where it contacts the hull.
8 Place the top half of the fairing block firmly against the inside hull.
9 Apply the included anti-seize compound to the exposed stem and anti-rotation bolt.

NOTE: Do not over-tighten the nut.
12 Place the anti-rotation bolt cap over the end of the anti-rotation bolt on the underside of the fairing, and cover
the cap with a smooth coating of sealant.
