Minn Kota Ulterra QUEST 90/115 MEGA Side Imaging 72" Trolling Motor

The Minn Kota Ulterra QUEST 90/115 with MEGA Side Imaging is the top-of-line freshwater electric-steer bow-mount trolling motor in the modern Minn Kota lineup. Combines three meaningful features in one trolling motor: the Ulterra Auto Stow / Deploy + Power Trim mechanism (push-button stow, deploy, and trim - no manual handling of the motor required), the QUEST brushless dual-voltage drive (more efficient and durable than older brushed motors, runs at 24V or 36V), and the built-in MEGA Side Imaging transducer (the high-resolution side-imaging sonar transducer mounted directly in the motor head, feeding HELIX-class fish finder displays). For tournament bass / walleye anglers running serious electronics setups, the Ulterra QUEST MSI 90/115 is the right call - you don't compromise on any of the three feature stacks.

What "Ulterra QUEST MSI" means. Three Minn Kota technologies stacked. "Ulterra" is the auto stow / deploy + power trim platform - the push-button mechanism that handles motor stow, deploy, and vertical trim adjustment automatically. "QUEST" is the brushless dual-voltage motor design - the same physical motor runs at 24V (90 lbs thrust) or 36V (115 lbs thrust), brushless drive for efficiency / durability / quiet operation. "MSI" is MEGA Side Imaging - the side-imaging sonar transducer built directly into the motor head, sending high-resolution imaging data to a connected HELIX fish finder. Three meaningful features combined into one trolling motor.

Auto Stow / Deploy and Power Trim. The Ulterra mechanism is the meaningful comfort feature versus traditional manual-deploy bow-mount trolling motors. Push a button on the wireless remote (or the foot pedal, the One-Boat Network app, or a connected HELIX fish finder), and the motor's onboard servos automatically deploy the unit from its stowed position over the bow into the water (or stow back up). Same for Power Trim - the motor's vertical depth adjusts at the push of a button. No manual lifting of a heavy trolling motor, no reaching down to adjust trim depth. For boat owners who deploy / stow the motor multiple times per day, the labor savings are meaningful - and if you've got back / shoulder issues that make manual handling painful, the auto mechanism is the difference between fishing and not fishing.

Brushless QUEST dual-voltage drive. The QUEST motor accepts 24V battery configurations (two 12V batteries in series, 90 lbs thrust output) or 36V battery configurations (three 12V batteries in series, 115 lbs thrust output). The brushless design eliminates the brush wear that limits the lifespan of conventional trolling motor drives. The motor runs cooler, draws less amperage at given thrust output, and runs quieter than the brushed alternative.

Built-in MEGA Side Imaging transducer. The MSI variant of the Ulterra QUEST has the MEGA Side Imaging transducer built directly into the motor head. MEGA Side Imaging is the modern high-frequency side-imaging sonar standard - meaningfully sharper detail than older 455 / 800 kHz side imaging, plus the bonus of being mounted in the trolling motor head where the transducer always faces the right direction during fishing operation. The integrated transducer feeds a connected HELIX-class fish finder display via the included connection cable - the fish finder shows the MEGA SI imagery as a sonar source. Cleaner installation than a separate add-on transducer (no dangling cable, no separate mounting), and the imaging is accurate because the transducer's always at the correct operating depth - it matches the motor's deploy depth.

72-inch composite shaft - lifetime guaranteed. The 72-inch shaft length is the right length for typical bass boats and large fiberglass walleye boats with elevated bow casting decks. Long enough to keep the prop deep when the boat is rocking in chop. Shorter than the 87-inch shaft used on big offshore-class inshore boats but longer than the 60-inch shaft used on smaller bass boats - the 72-inch is the most popular shaft length in the QUEST line. The shaft material is the proprietary Minn Kota indestructible composite - flexes under impact (hitting a stump, log, or rock) without breaking, where an aluminum or steel shaft would dent or snap. Lifetime warranty: if the shaft fails under normal use, Minn Kota replaces it.

Spot-Lock with Jog (5-foot nudge). Spot-Lock is the GPS feature that holds the boat at a fixed position regardless of wind / current. Push the Spot-Lock button, the motor takes over steering and thrust to keep the boat directly over the saved GPS location. The Jog addition lets you nudge the Spot-Lock position 5 feet in any cardinal direction without breaking lock - useful for systematically working a piece of structure without losing the lock and re-locking.

Drift Mode. Sets a heading and speed. the motor maintains that heading and speed regardless of wind / current pushing on the boat. The motor adjusts steering and thrust automatically to compensate. Useful for drifting depth contours or current edges at a specific speed without manual corrections - meaningfully better than drifting under wind / current alone (which doesn't track a contour).

Heel-toe programmable electric foot pedal. The Ulterra's electric foot pedal features heel-toe steering control (press toe forward to steer right, press heel forward to steer left) plus programmable shortcut buttons. The programmable buttons let you assign your most-used functions (Spot-Lock, AutoPilot, Drift Mode, anchor deploy on connected Talon, fish finder waypoint mark) for one-touch access during fishing. The foot pedal is included with the Ulterra QUEST - no separate purchase required.

Wireless remote control. The included wireless remote has an LCD screen with battery state, current speed, GPS heading, and active-mode display. Buttons cover Spot-Lock, AutoPilot, speed up / down, steering, Power Trim, auto stow / deploy, and the programmable shortcut buttons. The remote operates from anywhere on the boat without line-of-sight, so the angler can control the trolling motor from positions away from the foot pedal.

HELIX fish finder integration. The Ulterra QUEST MSI ships with the HELIX adapter cable and Ethernet cable for direct integration with select HELIX fish finders. Connect the cables, and the HELIX displays both the motor's MEGA Side Imaging feed AND control of the trolling motor's functions (Spot-Lock, AutoPilot, speed) directly on the fish finder screen - so the angler doesn't switch between the trolling motor remote and the fish finder display. Plug-and-play out of the box.

One-Boat Network app integration. The motor connects via the One-Boat Network mobile app (Apple iOS or Android). Speed, steering, Spot-Lock, AutoPilot, and over-the-air software updates - all from the phone or tablet. The app also enables programming the foot pedal's shortcut buttons and the wireless remote's programmable functions.

Real-time battery monitoring. The motor tracks battery state in real time and displays "time until empty" on the wireless remote and connected app. Eco-mode prompt at 20% battery state extends remaining runtime for the trip back to the dock.

Power consumption. The Ulterra QUEST 90/115 draws roughly 60 amps at full thrust on 36V (the maximum-thrust configuration). At typical fishing speeds (40-60% of full thrust), the draw is 25-40 amps. A typical 36V / 100Ah battery bank powers the motor for 6-10 hours of intermittent fishing use.

What's in the box. The Ulterra QUEST 90/115 trolling motor with built-in MSI transducer and 72-inch shaft, heel-toe electric foot pedal, wireless remote with lanyard, MKP-40 Power Prop (already installed), HELIX adapter cable, 30-foot Ethernet cable, mounting hardware kit. Required separately: a HELIX-compatible fish finder for the MSI feed and motor control integration, the appropriate 36V (or 24V) battery bank, and any additional Minn Kota accessories.

Install. Bolt-on bow mount to a flat bow surface or to a Minn Kota MKA bow accessory plate. Wire the motor's positive lead to the trolling motor battery bank's positive terminal through a 60-amp circuit fuse. Wire the negative lead to the bank's negative. Connect the foot pedal to the motor head via the supplied cable. Pair the wireless remote and the One-Boat Network app per the included instructions. Total install time is typically 4-6 hours for a competent boat owner.

Two-year motor limited warranty. Lifetime warranty on the indestructible composite shaft. MAP-enforced pricing.
