Garmin MotorGuide Trolling Motor Transducer Adapter Cable, 4-Pin to 8-Pin, 12 ft

Sonar adapter cable that bridges the built-in transducer of MotorGuide Xi3 and Xi5 trolling motors to Garmin echoMAP and GPSMAP chartplotters with an 8-pin transducer port. It delivers traditional 2D sonar directly from the trolling motor to the display, eliminating the need for a separate transom mount and ensuring clean, interference-free depth and fish readings at the bow.

Advantages

Plug-and-play installation with marine-grade connectors rated IPX7 for water resistance. The 12 ft (3.66 m) shielded cable routes easily through boat rigging tubes and compartments, maintaining signal integrity in both freshwater and saltwater. Compatible with a wide range of Garmin echoMAP CHIRP, ECHOMAP Plus, UHD, Ultra, and GPSMAP models featuring an 8-pin transducer input.

Suitable for

• Anglers using MotorGuide Xi3 or Xi5 trolling motors with built-in 4-pin sonar transducers
• Boaters who want bow-mounted sonar without installing a separate transducer
• Garmin echoMAP and GPSMAP users seeking a direct connection to their trolling motor's sonar
• Freshwater and saltwater fishing applications
