10. Apply a thick bead of marine-grade sealant:
i. all over the top face of the high speed nose cone, external isolator
plate, and external isolator sleeves, ensuring that they are completely
covered.
ii. 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.
iii. 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.
Assembling the internal components
Follow the steps below to fit the transducer to your hull.
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.
Mounting and sealant application
1. From inside the vessel, apply a continuous, thick bead of marine-grade
sealant all around the base of the protruding transducer stem and
anti-rotation bolt threads.
2. Guide the rubber washer down the transducer cable, and over the
threaded section of the transducer stem, compressing the sealant so that
the rubber washer sits flush on the hull.
3. If necessary, apply additional marine-grade sealant to the transducer
stem, above the rubber washer.
4. With the top face pointing upwards, guide the large isolator bush down
the transducer cable and over the transducer stem, ensuring it sits flush
on the rubber washer.
