Route The Cable; Permanently Mount The Transducer - Humminbird PiranhaMAX 155 Installation And Operation Manual

5. View the sonar signal on the display and compare against what was
observed in Step 2, making sure that the boat is in the same location
as it was during your observations in Step 2. If the results are
comparable, move on to Step 6. Otherwise, locate a new position in the
hull and repeat Steps 3 through 5.
6. Run the boat at various speeds and water depths while observing the
screen on the control head. If depth performance is required, test the
transducer in water at the desired depth. If the performance is
acceptable, move on to Step 7. If the performance is not acceptable,
repeat Steps 3 through 6.
7. Once you have determined the best mounting location using the above
steps, mark the position of the transducer.

Route the Cable

1. Once the mounting location is determined and you have marked the
position of the transducer, route the cable from the transducer to the
control head.

Permanently Mount the Transducer

1. Make sure the position of the
transducer is marked.
2. You may have to disconnect the cable to
the control head and reconnect it at the
end of this procedure.
3. Remove the water from inside the hull
and thoroughly dry the mounting
surface. If the surface is excessively
rough, it may be necessary to sand the
area to provide a smooth mounting
surface.
4. Mix an ample quantity of two-part slow
cure epoxy slowly and thoroughly.
Avoid trapping air bubbles (Figure 29).
5. Coat the face of the transducer and the
inside of the hull with epoxy (Figures 27
and 29).
