Installing the Transducer

Assembling the Transducer
1. Insert the rubber washer (Q) and plastic spacer (P) into
the transducer (G) at the same time. DO NOT lubricate
the rubber washer.
2. Route the cable toward the back of the transducer. Slide
the transducer into the transducer mount (H).
3. Place a 5 mm flat washer (J) on the 10-32 x 1.75" screw
(N), and insert the screw through the transducer mount,
spacer, and rubber washer.
4. Place the remaining 5 mm flat washer on the exposed
end. Install the 10-32 lock nut (L) finger tight. You can
tighten the transducer further after installation on the
boat.
