3. Assembling the transducer. Once you determine the correct posi-
tion for the ratchets, assemble the transducer as shown in the following
figure. Don't tighten the lock nut at this time.
4. Drilling mounting holes. Hold the transducer and bracket assem-
bly against the transom. The transducer should be roughly parallel to
the ground. The transducer's centerline should be in line with the bot-
tom of the hull. Don't let the bracket extend below the hull!
Mark the center of each slot for the mounting screw pilot holes. You
will drill one hole in the center of each slot.
Drill the holes. Use the #29 bit (for the #10 screws).
