using the 5/32” allen 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.
