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.
NOTE:
It is important to take your measurement in
the location shown in the illustration
Measuring the
Transom Angle
, from exactly 12 inches down from
the top of the transom.
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 (see the illustration
Transducer Knuckle Positions
). 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 (see the illustration
Ratchets Placed in Position 1
).
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.
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
illustration
