Connect Your HELIX 7 G3 or G3N to a Minn Kota Motor with Built-In MEGA Down Imaging
The Minn Kota MKR-MDI-2 adapter is the cable that makes it all work together. It connects a Humminbird HELIX 7 G3 or G3N fishfinder to a compatible Minn Kota trolling motor equipped with built-in MEGA Down Imaging sonar — letting you use your motor’s integrated transducer to display crystal-clear MEGA Down Imaging on your HELIX screen, without a separate transducer installation.
What It Does
- HELIX 7 G3 & G3N Compatible — Specifically designed for Humminbird HELIX 7 G3 and G3N fishfinder/chartplotter units
- Connects to Minn Kota MEGA Down Imaging Motors — Works with compatible Minn Kota Ultrex, Ulterra, and Terrova motors equipped with built-in MEGA Down Imaging sonar
- Shielded Cable — Shielded construction minimizes interference for clear, accurate MEGA Down Imaging sonar performance
- Plug-and-Play — Connects directly between your HELIX 7 G3/G3N and the motor’s sonar output; no additional hardware required
Compatible Units
Designed for use with the Humminbird HELIX 7 CHIRP MEGA DI GPS G4N and G3/G3N generation units. Compatible Minn Kota motors include the Ultrex, Ulterra, and Terrova series with built-in MEGA Down Imaging. Confirm your motor model includes built-in MEGA Down Imaging before ordering.
Parts Desk Insights
Best Use Case: This adapter is the essential link for bass and freshwater anglers who have a Minn Kota bow-mount trolling motor with built-in MEGA Down Imaging and want to display that sonar on their HELIX 7 G3 or G3N — without mounting a separate transducer on the motor or transom. It’s a clean, purpose-built solution that takes full advantage of the integrated sonar already built into your trolling motor.
Important: This adapter is for HELIX 7 G3 and G3N units only. It is not required for SOLIX series units, which connect differently. If you have a different HELIX generation, verify compatibility before purchasing.
