TRANSDUCER REPLACEMENT INSTRUCTIONS
Getting Started
WARNING
Always disconnect the motor from the battery before handling or working with the propeller, propeller drive
motor, electrical connections, or electronics enclosures to avoid serious injury or death.
CAUTION
For the best possible performance and to avoid potential injury, damage to the device, or damage to your vessel,
installation by a qualified marine installer is recommended.
When stowing or deploying the motor, be aware of the risk of entrapment or pinching from moving parts, which
can result in personal injury.
You should read these instructions completely before beginning this service, and make sure that you have the
tools and skill set needed to complete it. If necessary, you should use a qualified marine installer to ensure
proper service.
Tools Needed
• #2 and #3 Phillips screwdrivers
• 3 and 4 mm hex bits or drivers
• 4 mm ball-head hex bit or driver
NOTE: A ball-head bit is highly recommended due to the angle of some screws.
• Torque wrench
• Medium-strength thread-locking compound, such as LOCTITE

  • Page 2 Device Overview Shaft cap Power and transducer cables Steering system Mount Depth-adjustment collar Shaft Propeller drive motor Preparing the Motor for Transducer Replacement Before you can replace the transducer, you must perform these actions to prepare the motor. 1 Disconnect the motor from the power source. 2 Open the shaft cap (Opening the Shaft Cap, page 3).
  • Page 3 Opening the Shaft Cap WARNING Before you open the shaft cap, you must disconnect the motor from the power source. Failure to disconnect the power source can lead to electrical shock or damage to the motor. 1 Using a #2 Phillips screwdriver, remove the four screws that secure the lid of the shaft cap. You should place these screws in a safe place, because you must use them to close the shaft cap.
  • Page 4 Removing the Transducer Cable 1 Using a #2 Phillips screwdriver and a 3 mm hex bit or wrench, remove the three cable clamps that secure the power cable and the transducer cable to the trolling motor mount. 2 If necessary, pull the transducer cable out of the channel in the trolling motor mount. 3 Remove the plastic cable clamps that secure the transducer cable to the coiled power cable.
  • Page 5 Removing the Shaft Cap Before you can remove the shaft cap, you must remove the transducer cable from the shaft cap (Removing the Transducer Cable, page 4) and disconnect the cables in the shaft cap (Disconnecting the Cables in the Shaft Cap, page 3).
  • Page 6 Removing the Shaft from the Steering Servo Before you can remove the shaft from the steering servo, you must remove the shaft cap (Removing the Shaft from the Steering Servo, page 6). This procedure is best performed with two people. 1 Loosen the depth limiter screws and remove the depth limiter 2 Loosen the depth adjustment collar on the base of the steering servo 3 Slide the shaft down and out of the steering servo, taking care not to damage the skeg and transducer or snag the cables or connectors...
  • Page 7 Removing the Skeg and Nose Cone 1 Using a 4 mm hex bit or wrench, remove the four screws that secure the skeg to the propeller drive motor. 2 Remove the skeg. 3 Using a 4 mm hex bit or wrench, remove the two screws that secure the front of the nose cone to the propeller drive motor.
  • Page 8 Removing the Propeller Drive Motor Before you can remove the propeller drive motor, you must remove the shaft from the steering servo (Removing the Shaft from the Steering Servo, page 6). NOTE: When removing the propeller drive motor, using a ball-head hex bit or wrench is highly recommended because of the angle needed to reach the head of the screws.
  • Page 9 3 Straighten the cables at the top of the shaft, and slowly pull the propeller drive motor away from the shaft base until you can see the power and data cables connected to the propeller drive motor. 4 Holding the cables only, slowly pull them through the shaft, taking care that the ring terminals and data cable connector do not get caught on the top of the shaft.

  • Page 10: Removing The Transducer

    Removing the Transducer Before you can remove the transducer, you must remove the propeller drive motor (Removing the Propeller Drive Motor, page 8). 1 Carefully pull the transducer cable straight down through the bottom of the shaft until it is completely removed from the shaft.

  • Page 11: Installing The Transducer

    Installing the Replacement Transducer After you remove the existing transducer, perform these actions to install the replacement transducer. 1 Install the new transducer in the nose cone (Installing the Transducer, page 11). 2 Install the propeller drive motor on the shaft (Installing the Propeller Drive Motor, page 13).
  • Page 12 4 With the O-ring facing the transducer, feed the replacement transducer cable through the recessed nut and the hole in the front of the shaft base, but do not feed it up through the shaft. 5 After you have fed all but approximately 60 cm (2 ft.) of the transducer cable through the hole in the shaft base, feed the transducer cable up through the shaft.
  • Page 13 Installing the Propeller Drive Motor Before you can install the propeller drive motor, you must install the new transducer and route the transducer cable through the shaft (Installing the Transducer, page 11). 1 Remove the large 78 mm (3 in.) O-ring on the shaft base, and discard it. 2 Using the packet included in the transducer replacement kit, apply grease to the new 78 mm (3 in.) O-ring in the transducer replacement kit.
  • Page 14 10 If the power and data cables from the propeller drive motor are not already aligned and bundled, straighten, align, and bundle them with tape. If the power and data cables are not straight and aligned, they may not feed through the shaft smoothly. 11 Feed the power and data cables from the propeller drive motor up through the shaft until they emerge from the top.
  • Page 15 Installing the Nose Cone and Skeg Before you can install the nose cone and skeg, you must install the propeller drive motor on the shaft base (Installing the Propeller Drive Motor, page 13). 1 From the transducer replacement kit, select the cable gland that fits your transducer cable: •...
  • Page 16 9 Tighten the recessed nut until it stops, then loosen it of a turn. NOTE: For reference, the notches inside the recessed nut are centered of a turn apart. 10 Route the transducer cable through the nose cone so it will fit correctly onto the propeller drive motor. 11 Place the nose cone onto the propeller drive motor.
  • Page 17 Reinstalling the Shaft NOTE: We recommend having a second installer available to support the weight of the propeller drive motor while you feed the shaft through the steering servo housing. 1 Feed the transducer cable up through the steering servo housing. 2 Insert the shaft into the bottom of the steering servo housing, guiding the power and data connectors into the steering servo housing to prevent snagging the cables or connectors.
  • Page 18 7 Using a #2 Phillips screwdriver, install the 3 mm pan head screws to secure both halves of depth limiter together. When the depth limiter is installed properly, it rotates with the shaft and cannot slide up the shaft. 8 Reinstall the shaft cap (Installing the Shaft Cap, page 18).
  • Page 19 Installing the Transducer Cable in the Shaft Cap Before you can install the transducer cable in the shaft cap, you must install the shaft cap (Installing the Shaft Cap, page 18). 1 If previously removed, feed the transducer cable completely through the square hole in the shaft cap. 2 Install the grommet on the transducer cable.
  • Page 20 Connecting the Cables in the Shaft Cap Before you can connect the cables in the shaft cap, you must install the shaft cap (Installing the Shaft Cap, page 18). 1 Align the rings on the ends of the cables according to color. You must stack the red cables together and stack the black cables together, aligning the flat sides of the connectors on the cables.
