Minn Kota Fortrex Bow Mount Trolling Motor – 112 lb Thrust | 45" Shaft | 36V | Dual Spectrum CHIRP

Built for Serious Freshwater Anglers

The Minn Kota Fortrex is a full-featured bow mount trolling motor engineered for anglers who demand quiet, reliable power in demanding freshwater conditions. With 112 lbs of thrust and a 36-volt system, it handles large bass boats and heavy loads without breaking a sweat — keeping you on fish longer and with less fatigue.

Key Features

• 112 lbs Thrust / 36V — Moves heavy boats confidently in wind and current
• 45" Shaft — Ideal for most bass and walleye boats with moderate bow heights
• Digital Maximizer™ — Delivers up to 5× longer run time per charge by drawing only the power you need at variable speeds
• Built-In Dual Spectrum CHIRP Sonar — Transducer and wiring run fully concealed through the motor shaft; CHIRP technology produces sharper, more detailed fish and structure returns than traditional sonar
• Indestructible Composite Shaft — Flexes on impact rather than breaking; backed by a lifetime guarantee
• Nitrogen Gas-Charged Lift Assist — Cuts stow/deploy effort in half; makes rigging and unrigging at the ramp effortless
• Counter-Tension Stabilizer (CTS) — Integrated spring arm eliminates motor play, reduces noise, and lowers steering torque at higher speeds and in rough water
• Mono-Arm Mount — Single hinge point with rear pivot bearing for a quieter, stronger, longer-lasting mount than traditional scissor designs
• Marine-Grade Anodized Aluminum Beam — Lightweight and corrosion-resistant structural construction
• Removable Bowguard 360° — Detaches easily for portability and added security at the dock
• Redesigned Foot Pedal — Momentary button stays within easy reach; more precise speed control
• Illuminated Directional Indicator — Easy-to-read heading display at a glance

Best Use Case

The Fortrex is the right choice for freshwater anglers running large aluminum or fiberglass bass boats who want a dependable, no-frills bow mount with serious thrust and integrated sonar — without the added complexity of GPS or wireless control. It excels in open-water reservoir fishing, river systems, and anywhere you need consistent power and quiet operation across a full day on the water.

Looking for GPS anchor lock and wireless control? Consider stepping up to the Minn Kota Ultrex 112 lb / 45" / 36V or explore the full Ultrex Quest Series. Also available in the Fortrex 80 lb / 52" / 24V for smaller boats.

Pair with a compatible Humminbird fishfinder or chartplotter to get the most out of the built-in CHIRP sonar.

Parts Desk Insights

Best for: Anglers upgrading from a lower-thrust motor on a 17–21 ft bass or walleye boat who need maximum push without adding GPS complexity. The 36V / 112 lb configuration is the top of the Fortrex line — pair it with three 12V deep-cycle batteries wired in series for optimal performance.

Shaft length note: The 45" shaft suits boats with a bow height of 18–24". If your bow sits higher, measure carefully before ordering — shaft length cannot be changed after purchase.

Sonar compatibility: The built-in Dual Spectrum CHIRP transducer is designed to network with Humminbird units via Ethernet. It does not output a standalone transducer signal to third-party units.

Battery recommendation: For all-day use at high thrust, use AGM or lithium deep-cycle batteries rated at 100Ah or higher per bank. Lithium will maximize the Digital Maximizer's run-time advantage.
