If you need to increase the length of the transducer cable order part 
# ACC-DF-1130 from our website. Strip back the rubber cable cover 
1” (28 mm) exposing the three internal wires (blue, white, and bare) 
on your transducer. Using a soldering iron, solder the blue, white 

and bare wires from the extension cable to the corresponding wires on your 
transducer. Using electrical tape, or heat shrink tubing make certain that the 
soldered connections are completely sealed and protected against accidental 
electrical interference and corrosion. 

Cutting the plug off the Digital Depth 

Sounder display will void the warranty.

 

 

STEP 5   

Antifouling Paint 

Marine growth can accumulate rapidly on the transducer's surface. If the vessel 
is left in saltwater for extended periods of time, all components of the transducer 
below the waterline must be painted with WATER BASED antifouling paint. 

 

Never use ketone-based paint, as this type of paint can damage the 
transducer's plastic shell. 

 

Clear, spray-on antifouling paints are very easy to apply and can be 
purchased from your local boating supply store. 

 

Reapply paint as needed to prevent marine growth 

 

STEP 6   

Testing and Troubleshooting the Transom Mount Installation 

1.  Make sure that the display is functioning properly by following the display 

testing procedures in the Display Installation and Operation Manual. 

2.  Place the vessel in the water. Once the display is turned ON, it will display 

the test sequence and then display the current depth. 

3.  Become familiar with the depth  sounder’s function and performance at idle 

speeds. 

Gradually increase the boat speed and observe the depth readings 

(pay 

attention to minimum and maximum depth capabilities). 

5.  If "---" readings appear: 

 

Check to make sure that the transducer is not "kicked-up". To prevent 
damage to the transducer, it will automatically release from the mounting 
bracket (kick-up) when it is impacted. If this occurs, refer to Page 4 of this 
manual to reset the transducer for normal operation. If this happens 
frequently, make sure that the trailer or boat lift bunks do not interfere with 
the transducer during loading and unloading. 

 

Have someone run the boat on plane for you in smooth water. 
CAREFULLY look over the transom at the water flowing from the bottom
