Replacing the Force Trolling Motor Cable-Junction Box Seal

• 1. 1. Place the trolling motor into the deployed position so you can see the cable-junction box (1)

        

Examine the space between the cable-junction box and the steering servo housing (2)
              

If the motor has the seal installed, the additional layer between the cable-junction box and the steering servo housing will be visible (3).

Note: It is recommended to open the circuit breaker for the trolling motor or turn off the batteries when the boat is not in use as a matter of best practice.

New parts included:

1. 1. • Large square gasket

      • Three small screw washers (adhesive-backed)

      • Small round connector seal (no adhesive)

      • Thick round connector seal (adhesive-backed)

      • Thin round connector seal (adhesive-backed)

Spare parts included:

NOTE: These parts are needed only if the original parts are lost or damaged during service.

1. 1. • One M6 button-head screw (secures the pivot pin for the upper link)

      • One 6 mm washer (secures the pivot pin for the upper link)

      • Two M5x12 socket-cap screws (secures the cable-junction box to the steering servo housing)

Tools needed:

1. • Two 4 mm (5 /32 in.) hex bits or wrenches

Caution: Disconnect the trolling motor from power before beginning service to avoid potential injury and damage to the trolling motor.

1. 1. 1. Move the motor to the deployed position

      2. Disconnect the cable (1) from the display panel on the upper link of the mount (2)

         

      3. Using two 4 mm hex bits or wrenches, remove the screw and washer (3) from one side of the upper pin (4) on the steering servo housing

         

         • TIP: It is helpful to use the other 4 mm hex wrench to hold one end of the upper pin stationary while the screw is being removed

      4. Remove the upper pin from the steering servo housing

NOTE: Take care when removing the upper pin, because the motor swings freely on the lower pin and may damage the drive motor, propeller, or trailer.

1. 1. 1. Using a 4 mm hex bit or screwdriver, remove the three screws that secure the cable-junction box to the steering servo housing

         

         • NOTE: You may have to lift up on the upper link as much as allowed by the power cable to access the screws that secure the cable-junction box

      2. Carefully pull the cable-junction box away from the steering servo housing to remove it

NOTE: The cable-junction box connects to a PCB in the steering servo housing. When removing the box, take care to avoid damaging the connector on the PCB.

Caution: It is critical to examine the back of the cable-junction box for evidence of water intrusion after disconnecting it from the steering servo housing. If evidence of water intrusion is present, do not continue with this service.

1. 1. 1. Examine the back of the cable-junction box (1) for any evidence of moisture, especially in the cavity around the connector (2)

         

      2. Select an action:

         • If no moisture is present, continue with this service

         • If any moisture is present on the back of the cable-junction box or in the cavity around the connector, stop this service and contact Garmin product support for assistance

1. 1. 1. Using a damp cloth, lightly clean the surface of the steering servo housing around the connector (1)

         

      2. Remove the adhesive backing from the large square gasket (2) included in the kit

      3. Align the holes for the screws and connector, and press the gasket against the steering servo housing to adhere it in place

      4. Remove the adhesive backing (3) from one of the smallest washers included in the kit

         

      5. Place the washer, adhesive-side down, over one of the three screw posts (4) on the steering servo housing, and press to adhere it in place

      6. Repeat the previous two steps for the other two screw posts

1. 1. 1. On the back of the cable-junction box, remove the existing O-ring  (1) around the connector

         

      2. Position the small round flat seal (without adhesive) from the kit (2) around the connector on the cable-junction box, and press downward until it is firmly in place

         

      3. Remove the liner from the adhesive backing (3) on the thick round seal from the kit, position it around the connector on the cable-junction box, adhesive-side down, and press downward until it is firmly in place

         

      4. Remove the liner from the adhesive backing (4) on the thin round seal from the kit, position it around the connector on the cable junction box, adhesive-side down, and press downward until it is firmly in place

         

1. 1. 1. Examine the back of the cable-junction box and, if necessary, clean any dust or water deposits using a damp cloth

      2. Carefully align the connector on the back of the cable-junction box with the connector on the steering servo housing, and gently press it in place

         • NOTE: When reconnecting the cable-junction box, take care when aligning the connectors before pushing to avoid damaging them

      3. Using a 4 mm hex bit or screwdriver, install and tighten the three screws that secure the cable junction box to the steering servo housing

         

1. 1. Make sure the data cable (1) is accessible and is not trapped by any part of the mount

      

   2. Make sure the bushings (2) are in place in the upper holes on the steering servo housing

   3. Tip the top of the steering servo housing inward to align the holes on the upper link and the housing

   4. Push the pin (3) through the holes on the upper link of the mount and the steering servo housing

      

   5. Using a 4 mm hex bit or hex wrench, secure the pin using the screws and washers (4) on both sides

      

      • NOTE: To properly secure the pin, use two hex bits or wrenches so the pin does not rotate as the screws are tightened

   6. Reconnect the cable (5) to the display panel (6) on the upper link of the mount
