Minn Kota Ultrex QUEST 90/115 Trolling Motor | MEGA Down + Side Imaging | 24/36V | 52" Shaft
Minn Kota Ultrex QUEST 90/115 Trolling Motor | MEGA Down + Side Imaging | 24/36V | 52" Shaft
Minn Kota Ultrex QUEST 90/115 Trolling Motor with MEGA Down + Side Imaging – 52"
For tournament bass anglers and multi-species fishermen who want the complete package — premium MEGA imaging, cable-steer precision, and the versatility of the 52-inch shaft — the Minn Kota Ultrex QUEST 90/115 with MEGA Down + Side Imaging and a 52-inch shaft is the flagship configuration of the Ultrex QUEST lineup. It combines the ability to see offshore structure before you fish it with the prop depth and rough-water stability that most tournament bass boats and multi-species rigs demand.
Built on Minn Kota's QUEST brushless platform, this motor delivers 90 pounds of thrust on 24 volts or 115 pounds on 36 volts. The programmable heel-toe foot pedal provides the direct, mechanical cable-steer response tournament anglers rely on, while Spot-Lock with Jog, AutoPilot, and Drift Mode handle boat positioning when you need both hands free.
Why the 52" + MEGA Imaging Is the Tournament Sweet Spot
The 52-inch shaft is the most versatile option in the Ultrex QUEST lineup. It provides the extra prop depth needed for today's larger tournament bass boats and multi-species rigs while remaining easy to trailer and maneuver. For anglers fishing reservoirs, offshore ledges, wind-blown points, and expansive freshwater systems, the 52-inch shaft offers an ideal balance of control, performance, and versatility.
Pair that with integrated MEGA Down + Side Imaging and you have a motor that doesn't just hold position — it helps you find the fish before you ever drop the trolling motor. Scan both sides of the boat to locate brush piles and timber, use MEGA Down Imaging to study what's directly beneath you, then lock in with Spot-Lock and make the cast. That's the complete tournament workflow in a single integrated unit.
- 52" shaft — the sweet spot for most tournament bass boats and multi-species rigs
- MEGA Side Imaging — scan both sides to locate structure before driving over it
- MEGA Down Imaging — high-detail views directly beneath the boat
- Spot-Lock with Jog — hold position precisely while you fish the structure you found
- Cable-steer feel — instant response for precision boat control
- One-Boat Network — seamless Humminbird integration
Designed for Tournament Efficiency
With integrated MEGA Down + Side Imaging, anglers can locate offshore structure, identify fish-holding cover, move into casting position using precise cable steering, and hold the boat in place with Spot-Lock — all without changing equipment or adding an external transducer. Compatible Humminbird units further enhance this workflow through One-Boat Network, sharing waypoints and navigation data between the trolling motor and the fish finder seamlessly.
That's not a list of features. That's a complete tournament system.
Why Choose Built-In MEGA Down + Side Imaging?
Most trolling motors with integrated sonar offer traditional 2D CHIRP. This model goes further. The integrated MEGA Down Imaging and MEGA Side Imaging transducers give you a complete picture of the water column — what's beside the boat, what's beneath it, and where the fish are relating to structure — before you make the first cast.
The integrated transducer means a cleaner installation — protected inside the lower unit, fewer exposed cables, and seamless integration with compatible Humminbird displays through One-Boat Network.
MEGA Side Imaging — See What's Beside the Boat
- Scan both sides of the boat — cover more water with every pass
- Locate structure before driving over it — find brush piles, timber, and rock without spooking fish
- Cover water more efficiently — identify productive areas faster during pre-fish and tournament days
- Near-photographic detail — distinguish individual logs, rocks, and fish with exceptional clarity
- Ideal for offshore bass fishing — ledges, humps, deep points, and open-water structure
MEGA Down Imaging — See What's Beneath the Boat
- High-detail vertical imaging — see fish, baitfish, and structure with exceptional clarity
- Better separation of fish and structure — distinguish fish holding tight to brush or timber
- Excellent for vertical presentations — drop shots, football jigs, and deep jigging
- Superior bottom detail — identify bottom composition, transitions, and depth changes
- Works with Spot-Lock — hold position while you study the sonar and make precise casts
Which Sonar Version Is Right for You?
| Sonar Package | Best For |

Why Choose Ultrex QUEST?
Most retailers describe Ultrex as just another GPS trolling motor. It isn't. The biggest reason tournament anglers choose Ultrex over fully electric-steer motors is because it feels like a traditional cable-steer motor — with GPS features added on top, not the other way around.
Unlike Ulterra, which focuses on maximum automation with Auto Stow & Deploy and Power Trim, or Terrova, which emphasizes electric steering, Ultrex is built around control. Pair that with the premium MEGA imaging package and the versatile 52" shaft, and you have the motor most tournament anglers are looking for.
- Responsive cable steering — the defining feature
- QUEST brushless platform for more torque and longer runtime

Cable Steering — The Defining Feature of Ultrex
Ask any tournament angler why they chose Ultrex and the answer is almost always the same: it steers like a cable motor. That's not an accident — it's the entire design philosophy.
Cable steering delivers instant response the moment your foot moves. There's no lag, no interpolation, no electric motor translating your input. The connection between your foot and the prop is direct, mechanical, and immediate — exactly what anglers have relied on for decades of tournament fishing.
- Instant steering response with zero lag
- Natural cable-steer feel anglers already know
- Precise boat positioning for tight-quarters fishing
- Tournament-preferred steering feel
- Reduced cognitive load — steer by feel, not by thought
QUEST Brushless Technology
- Increased torque — more pulling power at all speed settings
- Quieter operation — brushless design eliminates motor noise that spooks fish
- Better efficiency — more runtime per charge than previous generations
- Dual-voltage flexibility — run 24V for 90 lbs or 36V for 115 lbs from the same motor
- Reinforced mount — engineered for larger, heavier boats
- Redesigned prop — improved thrust and weed resistance
- Improved durability — built for extreme freshwater fishing conditions
Spot-Lock with Jog
Minn Kota's legendary GPS anchoring holds your exact position automatically — compensating for wind, current, and wave action without any input from you. When you've located a brush pile or ledge with MEGA imaging, Spot-Lock keeps you positioned over it while you fish.
Use Jog to reposition in precise 5-foot increments from the Micro Remote. Learn more in our Spot-Lock Technology Guide.

Frequently Asked Questions
Why choose MEGA Down + Side Imaging over Dual Spectrum CHIRP?
Choose MEGA Down + Side Imaging if you spend significant time fishing offshore structure — ledges, brush piles, timber, humps, and deep points — where seeing the bottom before you fish it is a competitive advantage. MEGA imaging gives you near-photographic detail on both sides of the boat and directly beneath it. Choose Dual Spectrum CHIRP if you primarily use traditional 2D sonar, already own a forward-facing sonar unit, or don't need integrated Side Imaging.
Why choose the 52" shaft over the 45"?
The 52" shaft provides additional prop depth for larger, taller-bow boats and performs better in rough water or windy conditions where the bow rises and falls. If you fish a 19–21' tournament bass boat, a multi-species rig, or regularly fish open water and large reservoirs, the 52" is typically the better fit. The 45" is ideal for lower-profile bass boats with standard bow heights.
Why choose Ultrex instead of Ulterra?
Ultrex is designed for anglers who prefer the immediate response of cable steering while still benefiting from advanced GPS features like Spot-Lock and AutoPilot. Ulterra focuses on maximum automation with Auto Stow & Deploy and Power Trim — it's the right choice if you want the motor to do everything for you. Ultrex is the right choice if you want to stay in control.
Does Ultrex QUEST include Power Trim?
No. Power Trim is a feature of the Ulterra QUEST, not Ultrex. Ultrex uses a Lift-Assist mount for manual deployment and retrieval. If Power Trim is important to your fishing setup, the Ulterra QUEST may be a better fit.
What batteries do I need?
For 24V operation (90 lbs thrust), use two 12V deep cycle batteries. For 36V operation (115 lbs thrust), use three 12V batteries. We recommend lithium for maximum runtime and minimum weight. See our Battery Guide for complete recommendations.
