Minn Kota Ultrex QUEST 90/115 Trolling Motor | Dual Spectrum CHIRP | 24/36V | 60" Shaft
Minn Kota Ultrex QUEST 90/115 Trolling Motor | Dual Spectrum CHIRP | 24/36V | 60" Shaft
Minn Kota Ultrex QUEST 90/115 Trolling Motor with Dual Spectrum CHIRP – 60"
For anglers who fish larger freshwater boats, deep-V hulls, or regularly encounter rough, open-water conditions, the Minn Kota Ultrex QUEST 90/115 with a 60-inch shaft is a deliberate choice — not simply the longest option in the lineup. The 60" shaft is purpose-built for situations where the 52" falls short: bigger bows, bigger water, and conditions where keeping the prop submerged is the difference between holding position and losing it.
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 Choose the 60-Inch Shaft?
The 60-inch shaft is designed for anglers fishing larger freshwater boats or regularly encountering rough, open-water conditions. As bow height increases on larger fiberglass bass boats, deep-V walleye boats, and multi-species rigs, a 52" shaft can leave the propeller partially out of the water when the bow rises in waves or when the boat is running heavy. The 60" shaft provides the additional depth needed to maintain consistent thrust, reliable Spot-Lock performance, and stable boat control when conditions get serious.
Anglers who spend time on the Great Lakes, large inland reservoirs, or expansive open-water fisheries often prefer the 60" because it keeps the prop working when wind and waves would otherwise compromise a shorter shaft. It's also the preferred choice for deep-V walleye boats and larger multi-species rigs where bow height is significantly greater than a typical bass boat.
- Maximum prop depth for larger, taller-bow boats
- Best Spot-Lock stability in waves, wind, and current
- Consistent thrust when the bow rises in rough water
- Preferred by Great Lakes walleye and multi-species anglers
- Ideal for expansive reservoirs and open-water structure fishing
- The right choice when the 52" isn't enough
Shaft Selection Guide
| Shaft | Best For |
|---|---|
| 45" | Lower-profile bass boats |
| 52" | Most tournament bass boats and multi-species rigs |

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. That distinction matters on tournament day — and it matters even more on big water where conditions change fast.
- Responsive cable steering — the defining feature
- QUEST brushless platform for more torque and longer runtime
- Advanced GPS navigation (Spot-Lock, Drift Mode, AutoPilot)
- Spot-Lock with Jog for precise repositioning
- Dual-voltage 24V/36V operation
- Programmable heel-toe foot pedal
- Lift-Assist mount
- One-Boat Network compatibility
- Dual Spectrum CHIRP sonar
- Legendary tournament-proven steering feel
Best For
The 60" Ultrex QUEST is purpose-built for anglers who fish big water on bigger boats.
- Great Lakes walleye anglers
- Large inland reservoir fishing
- Multi-species boats with taller bows
- Deep-V hull fishing boats
- Rough-water bass tournaments
- Open-water structure and offshore humps
- Windy conditions where prop depth matters
- Long days on big water
- Anglers who regularly fish 22–26' boats
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. On big water, where you're constantly adjusting to wind and current, that instant mechanical response is even more valuable.
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.
- 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
The QUEST platform is Minn Kota's most advanced motor architecture ever developed. Every component has been redesigned from the ground up to deliver more performance with greater durability — especially important when you're running a 60" shaft on a larger, heavier boat.
- 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. On big water where conditions change constantly, Spot-Lock is the feature that keeps you on fish when other anglers are drifting off structure.
Use Jog to reposition your Spot-Lock location in precise 5-foot increments from the Micro Remote. When the fish are tight to a specific piece of structure, Jog lets you dial in your position without re-anchoring.

Dual Spectrum CHIRP Sonar
The integrated Dual Spectrum CHIRP transducer delivers outstanding traditional sonar performance when connected to a compatible Humminbird fish finder.
- Excellent fish arches and target separation
- Crisp bottom detail and structure identification
- Superior performance in deep water — especially relevant on big-water fisheries
- Clean, protected transducer installation — no separate transducer to mount
- Compatible with Humminbird HELIX and APEX units via One-Boat Network
Who should choose Dual Spectrum CHIRP instead of MEGA Side Imaging? This version is ideal for anglers who primarily use traditional 2D sonar, already own a Live Sonar unit, don't need integrated Side Imaging, or want the best possible fish separation and bottom detail without the added cost of MEGA imaging.
Programmable Heel-Toe Foot Pedal
- Customizable buttons — assign GPS functions to the positions that make sense for your fishing style
- Cable-steer feel — direct mechanical connection for instant response
- Integrated GPS controls — activate Spot-Lock, AutoPilot, and Drift Mode without reaching for a remote
- Reduced hand movement — keep your hands on the rod, not the remote

Frequently Asked Questions
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.
Why choose the 60" shaft over the 52"?
The 60" shaft is the right choice when the 52" isn't enough. If you fish a larger fiberglass bass boat, a deep-V walleye boat, or regularly encounter rough water, open-water reservoirs, or Great Lakes conditions where the bow rises significantly in waves, the 60" keeps the prop submerged and working when a shorter shaft would lose depth. The 52" is the sweet spot for most tournament bass boats; the 60" is for anglers who need more.
Why choose Dual Spectrum CHIRP over MEGA Side Imaging?
Dual Spectrum CHIRP is ideal for anglers who primarily use traditional 2D sonar, already own a Live Sonar unit, don't need integrated Side Imaging, or want excellent fish separation and bottom detail. On big-water fisheries where depth and structure are the primary targets, CHIRP often outperforms Side Imaging for the way these anglers fish.
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.
