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.
3.
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.
4.
Permanently Mount the Transducer
1. Make sure the position of the transducer is marked.
2. 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.
3. Mix an ample quantity of two-part slow cure epoxy slowly and thoroughly. Avoid trapping air
bubbles.
4. Coat the face of the transducer and the inside of the hull with epoxy (Figure 28).
5. Press the transducer into place with a slight twisting motion to purge any trapped air from
underneath, keeping the pointed end of the transducer body pointed forward, towards the bow
(Figures 26 and 29).
NOTE: Proper operation requires the pointed end of the transducer body to face towards the bow.
6. Weight the transducer so that it will not move while the epoxy is curing.
NOTE: When the epoxy cures, no water is necessary inside the hull.
7. If you unplugged the transducer cable at the beginning of this procedure, plug it back into the
control head.
NOTE: Neither water, spilled gasoline, nor oil will affect the performance of the transducer.
TROLLING MOTOR TRANSDUCER INSTALLATION
Several styles of the transducer are compatible with trolling motor mounting. (Figure 30). If you have a
trolling motor bracket, refer to the separate installation instructions that are included with the bracket.
NOTE: After trolling motor transducer installation, please perform the final testing and then finalize the
installation (see Test and Finish the Installation).
