Assemble the Transducer and Initial Mounting
In this procedure, you will assemble the transducer using the hardware provided, then mount it and make adjustments to its position
without locking it in place.
NOTE:
You will initially assemble the transducer and the pivot arm by matching the two ratchets to a numbered position on the
transducer knuckle. Further adjustments may be necessary.
Determine Your Transom Angle
1a.
If you already know your transom angle
, refer to the chart below for the initial position to use to set the ratchets. If your transom
is angled at 14 degrees (a common transom angle for many boats) use position 1 for the ratchets. In either case, go to step 2.
or...
1b.
If you do not know your transom angle
, measure it using a plumb line (weighted nylon string
or monofilament line) exactly 12 inches long. Hold the top of the plumb line against the top
of the transom with your finger, and wait until the line hangs straight down. Using a ruler,
measure the distance from the
bottom
of the plumb line to the back of the transom, then
use the chart. Refer to the illustration,
Measuring the Transom Angle
, for more information.
NOTE:
It is important to take your measurement in the location shown in the
Measuring the
Transom Angle
illustration, from exactly 12 inches down from the top of the transom.
Assemble the Transducer
2. Place the two ratchets, one on either side of the transducer knuckle, so that the beads on
each ratchet line up with the desired position number on the knuckle. If you are setting the
ratchets at position 1, the beads on each ratchet will line up with the rib on the transducer
knuckle to form one continuous line on the assembly.
NOTE:
The ratchets are keyed. Make sure that the square teeth on each ratchet face the square
teeth on the transducer knuckle, and the triangular teeth face outward.
3. Hold the ratchets on the transducer knuckle with one hand and fit the pivot arm over them
until it snaps into place with the other hand. Refer to the illustrations below.
