Minn Kota Ultrex QUEST 90/115 Trolling Motor

Thick hydrilla mats stall brushed lower units, making the Minn Kota Ultrex QUEST Trolling Motor the premier brushless bow propulsion system for competitive tournament bass anglers. Operating on dual 24V or 36V DC systems with a 60-inch carbon-fiber reinforced shaft, this motor delivers up to 115 lbs of thrust with programmable power steering to carve through heavy aquatic vegetation.

A redesigned heavy-duty cast aluminum Mono-Arm bracket supports an upgraded carbon-fiber composite shaft designed to withstand extreme wave impacts without bracket flex. The brushless motor pod eliminates commutators and carbon brushes, transferring rotational torque directly to the heavy-duty propeller. Weighing 68 lbs dry, this motor pulls 60A at peak 36V throttle, fitting a stowed deck boundary measuring 72 inches long by 15 inches wide.

Key Features of Minn Kota Ultrex QUEST

Tournament competitors who buy Minn Kota Ultrex QUEST trolling motor packages acquire brushless commercial power equipment built for extreme freshwater conditions. Its programmable Power Steering foot pedal allows anglers to adjust steering tension and customize foot buttons to control live-sonar transducers or shallow-water anchors.

- 115 lbs of peak thrust on 36V power holds heavy multi-species hulls over deep structure against ripping currents.
- 60-inch carbon-fiber composite shaft maintains propeller immersion through deep waves without surface cavitation blowout.
- Brushless direct-drive lower unit operates without carbon brushes, delivering silent propulsion and cooler running temperatures.
- Dual-voltage capability allows operation on 24V systems at 90 lbs thrust or 36V systems at 115 lbs thrust.
- Ultrex QUEST tournament bass motor platform links directly with Humminbird fishfinders via One-Boat Network integration.
- Enhanced Spot-Lock GPS virtual anchor incorporates drift-monitoring software to hold coordinates in rolling swells.
- Power Steering foot pedal combines traditional cable-steer feel with effortless electronic power assist.
- Reinforced lift-assist bracket uses high-torque gas springs to cushion stowage on elevated bow decks.

Thrust Curves Battery Amp Draw

Producing 90 lbs of thrust at 24V and 115 lbs at 36V, this brushless lower unit draws 60A at wide-open throttle with exceptional thermal efficiency. Powered by a 36V 100Ah lithium iron phosphate battery, it delivers over 18 continuous hours of boat control at 45 percent throttle. The high-torque direct-drive motor chops through dense weed patches without motor bogging, emitting under 32 dB(A).

Bow Deck Installation Geometry Clearances

Fasten the cast aluminum base through the forward deck using six stainless machine bolts and backing plates, allowing 4.5 inches of rubrail overhang. Connect the main power cable to a 60A waterproof marine circuit breaker using heavy 6 AWG tinned copper wire. The base fits standard heavy-duty freshwater mounting profiles.

Deck Usability Rigging Inspection Tasks

Operating the foot pedal provides natural mechanical feedback while allowing digital tension adjustments through the One-Boat Network application. This 60-inch brushless motor is not engineered for low-freeboard aluminum jon boats, small canoes, or vessels displacing under 1200 lbs.

- Inspect the prop drive pin and remove wrapped monofilament behind the hub after each outing.
- Wipe down the composite shaft, remote screen, and mount hinges with freshwater after each outing.
- Inspect remote battery charge and verify power harness terminal torque every 50 runtime hours.
