1b. If you do not know your transom angle,
measure it using a plumb line (weighted
nylonstring 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
backof the transom, then use the chart.
NOTE:It is important to take your measurement in
thelocation shown in theillustration Measuring the
TransomAngle, from exactly 12 inches downfrom
thetop of the transom.
2. Placethe two ratchets, one on either side of the transducerknuckle, so
thatthe beads on each ratchet line up with the desiredposition number
onthe knuckle (see the illustrationTransducer KnucklePositions). If you
aresetting the ratchets at position1, thebeads on each ratchet will line
upwith the rib on the transducer knuckle to formone continuous line on
theassembly (see the illustration RatchetsPlaced in Position 1).
NOTE:The ratchets are keyed; make surethat the square teeth on each ratchet
facethe square teeth on the transducer knuckle, and the triangular teeth face
outward.
Holdthe ratchetson the transducerknuckle withone hand and fit thepivot
armover them until it snaps intoplace with the other hand. Referto the
illustrationFittingthe Mounting BracketOver the Ratchet.
