wrench provided. The screws are visible through the access holes on each side of the metal
bracket. Check to make sure the transducer main body is rigidly fastened to the pivot. (See
Figure H)
Step 6
CHECK POSITION OF TRANSDUCER- At this point, check to see that the bottom of the
transducer is a minimum of ¼” below the bottom of the transom. (However, as noted in STEP 2,
the top of the transducer cannot fall below the bottom of the transom). If it is not, remove the
transducer assembly from the metal bracket by removing the pin installed during STEP 3. Loosen
the metal bracket mounting screws, re-position the bracket utilizing it’s slotted holes, tighten and
re-assemble. It may be necessary to replace the silicone sealant after this adjustment is made.
NOTE: It may be necessary to make several high speed runs to adjust transducer either
UP/DOWN or to re-adjust the angle to achieve optimum results.
Step 7
CABLE CLAMPS- Install cable clamps as necessary by drilling a 1/8” dia. hole for the # 8 screw
supplied.
2. INSIDE HULL MOUNTING PROCEDURE
Warning: In order to achieve proper results with this type installation, it is important that the
transducer be mounted by someone familiar with the use of two part epoxy adhesives. For this
reason, Techsonic Industries, Inc. will not be responsible for any damage due to the mounting of
your transducer in this manner.
NOTE: An Epoxy Kit (Part N. EPK) is available from Humminbird. This Epoxy Kit has been
formulated for Inside Hull Transducer Installation.
1. Select as flat an area as possible near the aft end and center of boat where the hull is thin
and not double. If the bottom has a runner down the center of boat, select an area to one side
of the runner, but as close to the runner as possible.
2. Clean the inside of the boat with lacquer thinner in the area transducer is to be mounted.
Outside of boat in this area should also be cleaned. (Not with lacquer thinner).
3. Put approximately one inch of water in the bottom of the boat.
4. Put transducer in the water. The bottom of the transducer should be in a flat area and should
be in good contact with the bottom of the boat.
5. Operate the LCR with the boat operating at high speed. The transducer may have to be
moved in order to find an area where satisfactory operation is observed.
6. When an area is found that produces satisfactory operation, mark the location of the
transducer.
