Minn Kota MKR-US2-8 Humminbird 7-Pin Adapter Cable

Enhance your fishing setup by seamlessly linking your Humminbird fishfinder to a Minn Kota trolling motor equipped with Universal Sonar 2. This specialized 7-pin adapter cable bridges the gap, delivering crystal-clear 2D sonar readings straight from the transducer mounted on your motor. Anglers swear by its reliability on the water, where every detail counts for spotting structure, baitfish, and that trophy catch lurking below.

Universal Sonar 2 packs advanced water temperature sensing alongside DualBeam PLUS technology, giving you wide and narrow cone views for comprehensive coverage. Whether you're finesse fishing shallow weedlines or probing deeper basins, this adapter ensures your Humminbird unit taps into those precise signals without fuss. Forget tangled wires or signal dropouts—its shielded design and rugged build keep interference at bay, even in choppy conditions.

Standout Features That Deliver on the Water

• Precision Connectivity: Plugs your Humminbird 7-pin fishfinder directly to the Universal Sonar 2 transducer for instant sonar integration.
• Interference-Free Performance: Metal-tipped connectors block sonar noise, ensuring clean, accurate readings at 200 kHz/83 kHz frequencies.
• Battle-Tested Durability: IP68-rated waterproofing submerges fully without worry, perfect for bow-mount trolling motors.
• Compact and Flexible: 16-inch length offers just enough reach for clean routing on most setups.
• Shielded Protection: Internal shielding guards against electrical noise from the motor or nearby electronics.

Real-World Benefits for Serious Anglers

Picture this: You're idling over a promising flat, and your Humminbird screen lights up with detailed bottom contours and suspended fish—powered by the transducer already on your Minn Kota. No need for extra mounts or batteries; it's plug-and-play simplicity that saves time and deck space. This adapter shines in tournaments or multi-day trips, where dependable sonar means more bites and bigger limits. Plus, water temp data helps you adjust lures on the fly, dialing in for species like walleye or bass in changing conditions.

Backed by a limited one-year warranty, it reflects Minn Kota's commitment to quality gear that withstands harsh marine environments. Seasoned guides often pair it with Ulterra or Terrova motors for spot-on performance without compromising stealth.

Extensive Compatibility Across Humminbird Lineups

This adapter works with a wide array of Humminbird models featuring 7-pin connectors. Here's a breakdown by series for quick reference:

Helix™ Series

Other Popular Series (1100, 900, 800, and More)

Includes models like 1199ci HD SI Combo, 999ci HD SI Combo, 899ci HD SI Combo, 788ci HD Combo, and classics such as PiranhaMAX 155, Matrix series, Fishfinder 500/700 series. For full older model lists like PiranhaMAX 4-230PT, 141c-958c, check your unit's connector—7-pin units pair perfectly.

Simple Installation Tips

Route the cable along your trolling motor's shaft, securing with zip ties to avoid snags. Connect the 7-pin end to your Humminbird and the other to the US2 transducer port. Power cycle your fishfinder, select the external transducer source, and you're scanning. Pro tip: Test in shallow water first to verify readings match expectations.

Key Considerations for Optimal Use

This setup excels with traditional 2D sonar. Minn Kota motors with built-in Universal Sonar 2 (even i-Pilot Link models) aren't compatible with Humminbird Down Imaging. For DI features on Helix 12/10/9, 1100/900/800 series, or certain Helix 7/5, add an external XTM 9 WIDE DI 20 T or XTM 9 DI 25T transducer.
