If you’re choosing between the Minn Kota Ultrex Quest and the MotorGuide Xi5, you’re shopping for the best GPS-enabled trolling motor money can buy. Both have legions of loyal anglers. Both integrate with major fish finder brands. But they take very different approaches to boat control, and the right choice depends on how you fish.
Quick Verdict
The Minn Kota Ultrex Quest wins for Humminbird users, anglers who prioritise hands-free boat control, and those who want the most advanced steer-by-wire technology. The MotorGuide Xi5 wins for anglers who prefer Garmin integration, want a more affordable entry point into GPS trolling, and fish primarily in open water scenarios.
Design Philosophy
The Ultrex Quest uses Minn Kota’s acclaimed Universal Sonar 2 integration and features their redesigned brushless motor system delivering 112 lbs of thrust. The Quest model added significant improvements to the motor, cable management, and control interface over the original Ultrex.
The MotorGuide Xi5 uses a 55 lb, 80 lb, or 105 lb thrust brushless motor with Pinpoint GPS technology. It’s available in 24V and 36V configurations and connects directly to Garmin chartplotters for full integration with Garmin’s ActiveCaptain and Force ecosystem.
GPS Accuracy & Anchor Performance
Both motors offer GPS anchor modes — hold your boat in position without a physical anchor. The Ultrex Quest’s Spot-Lock Jog feature lets you move your anchor point in precise 1.5-metre (5-foot) increments using a remote or through the Humminbird head unit — incredibly useful when you need to reposition slightly on a snag pile or rock structure. The Xi5’s GPS anchor is equally reliable in calm to moderate conditions, though in current or significant wind, the Ultrex Quest’s higher thrust and advanced motor control gives it a slight edge in holding power.
Ecosystem Integration
This is the most important factor for most buyers:
- Minn Kota Ultrex Quest integrates natively with Humminbird fish finders via One-Boat Network. Control Spot-Lock directly from your Humminbird screen, share waypoints instantly, and use your fish finder’s mapping to navigate the trolling motor — all without a separate remote.
- MotorGuide Xi5 integrates natively with Garmin chartplotters via the Garmin Marine Network. Control the motor from your Garmin ECHOMAP or GPSMAP display, follow routes, and use Panoptix data to guide the motor toward fish.
The takeaway is straightforward: if your fish finder is Humminbird, the Ultrex Quest is the obvious choice. If you’re running Garmin, the Xi5 is the natural pairing.
Steer & Noise
The Ultrex Quest uses a universal mount with integrated steering — the motor steers via an internal mechanism rather than a cable-pull system, making it quieter and more precise. The elimination of cables also means fewer maintenance headaches over time. The Xi5’s prop-steering design is also well-regarded for quiet operation, particularly its brushless motor in newer versions.

| Max Thrust | 112 lbs | 105 lbs |
| Motor Type | Brushless | Brushless |
| Voltage | 24V / 36V | 24V / 36V |
| GPS Anchor | Spot-Lock + Jog | Pinpoint GPS |

Both motors run from 24V or 36V battery banks — ask our team about lithium battery systems and 230V shore-power chargers specified for UK/EU marine electrical systems.
Remote Control
The Ultrex Quest ships with a Bluetooth remote that controls Spot-Lock, speed, and steering. The Xi5 includes MotorGuide’s Pinpoint GPS remote. Both are solid wireless remotes — but the Ultrex’s deeper integration with Humminbird screens reduces how often you even need the remote once you have a head unit controlling everything.
Who Should Choose the Ultrex Quest?
- Humminbird XPLORE, APEX, or SOLIX users who want seamless One-Boat Network control
- Competitive lure anglers who need the highest precision Spot-Lock for structure fishing
- Anglers willing to invest in the most advanced steer-by-wire trolling motor available
- Boats 5.5–7.5 metres (18–24 feet) where maximum holding power in wind and current is essential
Who Should Choose the MotorGuide Xi5?
- Garmin ecosystem users who want chartplotter-controlled trolling motor navigation
- Anglers looking for excellent GPS anchor performance at a more accessible price
- Zander, perch, and open-water anglers who drift slower and need reliable positioning
- Smaller boats where 105 lbs thrust is sufficient
