2. The epoxy consists of the epoxy itself and a hardener. Remove the
two compounds from the package and place them on the paper plate.
Thoroughly stir the two compounds together until the mixture has a
uniform color and consistency. Do not mix too fast or bubbles will form
in the epoxy. After mixing, you have 20 minutes to complete the instal-
lation before the epoxy becomes unworkable.
Spread a thin layer of epoxy (about 1/16" or 1.5 mm thick) on the face of
the transducer as shown in the previous figure.
Make sure there are no air pockets in the epoxy layer! Then, apply the
remaining epoxy to the sanded area on the hull.
3. Press the transducer into the epoxy, twisting and turning it to force
any air bubbles out from under the transducer face. Stop pressing when
you bottom out on the hull. When you're finished, the face of the trans-
ducer should be parallel with the hull, with a minimum amount of
epoxy between the hull and transducer.
4. Apply a weight, such as a brick, to hold the transducer in place while
the epoxy cures. Be careful not to bump the transducer while the epoxy
is wet. Leave the weight in place for a minimum of three hours. Allow
the epoxy to cure for 24 hours before moving the boat.
5. After the epoxy has cured, route the cable to the sonar unit and it's
ready to use.
Power Connections
(permanent mount only)
The unit works from a 12-volt battery system. You can attach the pow-
er cable to your boat's accessory or power buss (or directly to the bat-
tery). If you use an accessory buss but have problems with electrical
interference, attach the power cable directly to the battery. If the cable
is not long enough, splice #18 gauge wire onto it.
CAUTION:
When using
the unit in a saltwater environment, we strongly rec-
ommend that you shut off the power supply to the power cable
when the unit is not in use. When the unit is turned off but still
connected to a power supply, electrolysis can occur in the power ca-
ble plug. This may result in corrosion of the plug body along with
the electrical contacts in the cable and the unit's power socket.
In saltwater environments we recommend you connect the power
cable to the auxiliary power switch included in most boat designs.
If that results in electrical interference, or if such a switch is not
available, we recommend connecting direct to the battery and in-
stalling an inline switch. This will let you shut off power to the
