4. Fill the hull with enough water to submerge the
transducer body. Use a sand-filled bag or other heavy
object to hold the transducer in position. The
transducer cannot transmit through air, and the water
purges any air from between the transducer and the
hull, and fills any voids in the coarse fiberglass surface.
5. View the sonar signal on the display and compare
against what you 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. 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 create a smooth mounting surface.
3. Slowly and thoroughly mix an ample quantity of two-part slow cure epoxy.
Avoid trapping air bubbles.
4. Coat the face of the transducer and the inside of the hull with epoxy.
5. Press the transducer into place with a slight twisting motion to purge any
trapped air from underneath, keeping the end of the transducer that has the
mounting ears pointed forward, towards the bow of the boat.
NOTE:
Proper operation requires the end of the transducer that has the mounting ears to
face towards the bow of the boat.
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.
