GT56UHD-TR transducer - Force® Kraken 75" electric motor

The Garmin GT56UHD-TR is a replacement transducer designed specifically for the Garmin Force Kraken electric motor. This transducer restores the ultra-high definition (UHD) detection capabilities of your system, essential for detailed visualization of underwater structures and fish. It is compatible with Garmin Force Kraken motor models measuring 1.9 m (75"), ensuring seamless integration and maintaining original performance.

Detailed replacement procedure

Replacing the Garmin GT56UHD-TR transducer involves a series of precise steps, as outlined in the official instructions. The process begins with fully disconnecting the motor from its power source, followed by opening the shaft cap and carefully unplugging the cables (USB, data, and transducer). The propeller drive motor must then be removed from the shaft, which requires unscrewing six bolts and handling the cables with caution. The old transducer is then extracted after removing the skeg and nose cone.

Installation and component integration

Installing the new Garmin GT56UHD-TR transducer is simplified by the inclusion of new bolts, washers, O-rings, neoprene bushings, and marine grease. After preparing the nose cone with the new bushing and transducer, the cables are carefully routed through the shaft. The motor seals are replaced, and marine grease is applied to ensure optimal waterproofing. Assembling the propeller drive motor onto the shaft requires using medium-strength thread-locking compound (such as LOCTITE 243) and tightening to a torque of 4 N·m (35 lbf·in) to guarantee a secure and watertight connection. The final steps include reconnecting the cables in the shaft cap and restoring power to the motor.
