QUEST Brushless 90/115 LB Performance

The Minn Kota Ultrex QUEST 90/115 52″ MSI and Micro Remote uses Minn Kota’s QUEST brushless motor technology rather than the brushed architecture found on standard Ultrex models.

The dual-voltage system gives anglers two power configurations. On a manufacturer-approved 24V system, the motor produces up to 90 lb of thrust. When configured for 36V, maximum thrust increases to 115 lb.

Brushless technology is designed to improve efficiency, torque and durability while reducing the internal wear associated with conventional motor brushes. This makes QUEST particularly attractive to anglers who spend long days controlling larger freshwater fishing boats.

For general background about this type of electric propulsion, see the Wikipedia overview of trolling motors.

Built-In MEGA Side Imaging

The defining sonar feature of this configuration is Built-In MEGA Side Imaging (MSI).

The imaging transducer is integrated directly into the trolling motor’s lower unit. This eliminates the need to clamp a separate imaging transducer to the trolling motor and run an exposed sonar cable down the shaft.

When paired with compatible Humminbird electronics, MEGA Side Imaging provides detailed views of underwater areas extending to either side of the boat.

This can help anglers identify submerged timber, rocks, vegetation, drop-offs, fish-holding structure and other targets without having to position the boat directly above them.

Side Imaging + Down Imaging + CHIRP

The MSI configuration provides more than Side Imaging alone.

With compatible Humminbird equipment, the Built-In MEGA Imaging system supports applicable MEGA Side Imaging, MEGA Down Imaging and Dual Spectrum CHIRP 2D sonar capabilities.

That makes the Minn Kota Ultrex QUEST 90/115 52″ MSI and Micro Remote a strong choice for anglers building a Humminbird-based bow electronics system.

Because compatibility differs among Humminbird generations and models, check your exact fish finder through Minn Kota’s official Built-In MEGA Imaging compatibility guide.

MSI vs. MDI vs. DSC

Choosing the correct sonar configuration is important when purchasing an Ultrex QUEST.

DSC – Dual Spectrum CHIRP: Provides traditional 2D CHIRP sonar for fish arches, target separation and bottom information.

MDI – MEGA Down Imaging: Adds detailed imaging directly beneath the boat while retaining applicable 2D sonar capabilities.

MSI – MEGA Side Imaging: Adds detailed Side Imaging while supporting applicable Down Imaging and 2D sonar capabilities through compatible Humminbird electronics.

For anglers who want the broadest integrated imaging coverage, MSI is the most capable of these three sonar configurations.

Power Steering + Cable-Steer Response

Ultrex QUEST maintains the steering characteristics that make Ultrex popular with bass anglers.

Its heel-toe cable foot pedal provides immediate steering response while Power Steering reduces the physical effort required to turn the motor.

This combination allows anglers to control direction primarily by foot while keeping both hands available for casting, retrieving and handling fish.

The QUEST platform then adds brushless power and updated electronics without giving up the familiar cable-steer feel.

Advanced GPS and Spot-Lock

The Minn Kota Ultrex QUEST 90/115 52″ Shaft 24/36V MSI and Micro Remote includes Minn Kota’s advanced GPS boat-control technology.

Spot-Lock uses GPS to help maintain the boat at a selected fishing position. This can be particularly useful when fishing offshore structure, points, submerged vegetation or other locations where repeatedly maintaining position manually would be difficult.

The system also supports features such as AutoPilot and Drift Mode, giving anglers additional ways to manage direction, speed and boat movement.

One-Boat Network Integration

Ultrex QUEST is compatible with Minn Kota and Humminbird’s One-Boat Network.

When connected to supported Humminbird equipment, trolling-motor controls, GPS navigation, sonar and mapping functions can work together as an integrated system.

This integration becomes particularly valuable with the MSI configuration because anglers can combine detailed Side Imaging with GPS trolling-motor control and compatible chartplotter functions from their Humminbird electronics.

52-Inch Shaft

The 52-inch shaft provides seven inches of additional reach compared with the 45-inch Ultrex QUEST.

The longer shaft can be advantageous on compatible boats with a greater bow-to-waterline measurement or when fishing conditions cause more vertical movement at the bow.

Correct trolling-motor shaft length helps keep the propeller adequately submerged without creating excessive shaft height above the deck.

Micro Remote

The included Micro Remote provides compact wireless access to supported trolling-motor functions.

Anglers can use the heel-toe pedal for precise steering while keeping the Micro Remote available for convenient wireless control when moving away from the bow.

Its compact design also makes it convenient to carry on a lanyard.

QUEST Durability

Minn Kota designed the QUEST platform for demanding use, including reinforced components and a strengthened composite shaft.

The brushless architecture also eliminates conventional motor brushes, while the QUEST shaft construction is engineered to withstand demanding trolling-motor applications.

This combination of durability, efficient power and advanced electronics makes the Minn Kota Ultrex QUEST 90/115 52″ MSI and Micro Remote a substantial upgrade from older cable-steer trolling motors.

How to Use the Ultrex QUEST 90/115 52″ MSI

Mount the motor securely on a compatible bow following Minn Kota’s installation instructions for the exact model. Because this trolling motor supports 24V and 36V operation, its electrical system, circuit protection and marine-grade components should follow Minn Kota’s specifications for the selected voltage.

Use the assisted mechanism when manually deploying and stowing the motor. The heel-toe pedal controls steering and variable speed, while the Micro Remote provides supported wireless functions.

Activate Spot-Lock when GPS-assisted position holding is needed. Connect Built-In MEGA Side Imaging to compatible Humminbird electronics using the manufacturer-specified sonar connection or adapter.

For detailed installation and operating procedures, consult the official Minn Kota Ultrex manuals and installation guides.
