Assembling the external components

The steps below will guide you through the assembly of the external components.

Note

To achieve a long lasting watertight seal, ensure that all parts are clean and dry and apply a generous amount of marine-grade sealant to all mating surfaces.

  1. Ensure correct orientation using the markings and labels on the top face of the transducer.
  2. Remove the orientation labels and clean to ensure there is no residual label glue.
  3. Using an appropriate cloth and cleaning agent (for example: isopropyl alcohol), wipe clean ALL surfaces of the supplied components and the mounting location, both outside and inside the hull ensuring that they are free from grease and debris.
  4. Ensure all surfaces are dry.
  5. Marine-grade sealantApply a thick bead of marine-grade sealant all over the top face of the transducer so that it is completely covered.
  6. Feed the transducer cable, stem and anti-rotation studs through the holes in the high speed nose cone, positioning the high speed nose cone over the transducer, and then slide the transducer into the nose.
  7. Apply pressure to the high speed nose cone, to compress the sealant against the transducer.
  8. Feed the transducer cable through the stem hole in the external isolator plate, and then position the external isolator plate in the recess in the top of the high speed nose cone.
  9. Feed an external isolator sleeve over both of the anti-rotation studs, positioning them in the hole recesses in the top of the high speed nose cone.
  10. Apply a thick bead of marine-grade sealant:
    1. all over the top face of the high speed nose cone, external isolator plate, and external isolator sleeves, ensuring that they are completely covered.
    2. all around the bottom part of the threaded section of the transducer stem and the anti-rotation studs, ensuring that the sealant will protrude approximately 6 mm (0.24 in) above the final tightened nuts.
    3. all around and inside the holes you have drilled in the hull.
  11. Guide the transducer cable through the large stem hole in the hull.
  12. Guide the transducer stem and anti-rotation studs up through the holes in the hull.
  13. Support the transducer from beneath.
