1. Assemble the stainless steel brackets to the transducer using the
hardware furnished. Do not tighten until final adjustments are made.
2. Place assembly on transom at selected
location with the front of the transducer
extending 1/2" to 5/8" below the bottom of
the boat and with the front part against the
transom. The least amount that the
transducer extends below the bottom is
desired. If too low, spray and turbulence will
occur.
3. With transducer in place, mark location of slotted holes in brackets.
4. Drill in center of slot outline with a 9/64" (3.5mm) drill, 3/4" (19mm)
deep.
5. Fasten the transducer to the transom using the #10 x 3/4 screws.
6. Before final tightening the 4 screws holding the brackets to the
transducer, tip the rear edge down approximately 1/8" as shown.
7. Tighten all screws. CAUTION. DO NOT use any
thread locking compound on the screws. Most
products such as LOCTITE contain chemicals that
attack and weaken plastics. IMPORTANT. There
should be no gap between the brackets and the
transducer. A wide space between these parts will
cause stress on the transducer mounting ears and result in breakage
with time.
8. In running the cable to the sounder, avoid proximity to other wiring on
the boat, particularly ignition and alternator cables. They can be a
source of noise on the sounder display.
Puck Style Transducers
There are two ways in which the puck style transducer can be mounted. It
can be mounted in-­hull or on an electric trolling motor.
In-­Hull Mounting
This method, gluing the transducer to the hull, gets the same results as if
you were using the high speed transducer, only there are no holes to drill
in the boat and there is no transducer on the transom to get damaged by
impact.
Finding the best location for the transducer before you mount it is critical.
Choose a flat smooth spot near the center of the bilge and near the back
of the boat. It is a good idea to make a "test run" before you permanently
install the transducer to make sure that you can indeed get a reading
through your hull and when the boat is on plane. Put about a half inch of
water in the bilge and hold the transducer in the intended location. Move
the transducer around until you get the best reading. Mark that spot.
