Installing Your Fishfinder

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.

1.  Slide the large cable tie (S) through the slot on the 

transducer mount (H) with the ridges of the band facing 

up until equal lengths extend on both sides of the mount. 

(

NOTE: For cold water, or heavy timber or debris areas, 

a metal 4-5" worm gear clamp is recommended.)

2.  Position the mount gasket (I) on the curved top of the 

transducer mount.

3.  Place the transducer assembly against the motor body of 

the trolling motor, with the front of the 

transducer pointed away from the 

trolling motor propeller.
