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.
5. Press the transducer into place with a slight
twisting motion to purge any trapped air from
underneath.
NOTE: Puck or round, circular-bottomed transducers
have no directional bias, and therefore orientation of
these types of transducers is not as important.
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 depthsounder.
NOTE: Neither water, spilled gasoline, nor oil will affect the performance of the transducer.

3. Place the transducer body face down on the inside
of the hull in the area you have selected.
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 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
depthsounder. 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. Routing 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 depthsounder.
CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable insulation.
Route the cable as far as possible from any VHF radio antenna cables or tachometer cables to
reduce the possibility of interference. If the cable is too short, extension cables are available to
extend the transducer cable up to a total of 50' (15 m). For assistance, contact the Customer
Resource Center at www.humminbird.com or call 1-800-633-1468 for more information.
4. Permanently Mounting the Transducer
NOTE: Once permanently mounted, you will not be able to make further adjustments to 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.
