Minn Kota Terrova 112 36V 72" MEGA Down Imaging

The Minn Kota Terrova 112 Trolling Motor with Wireless Remote and MEGA Down Imaging is Minn Kota's premium 36V electric-steer bow-mount freshwater trolling motor - 112 lb thrust, 72-inch shaft, built-in Spot-Lock GPS, AutoPilot, wireless remote, and integrated MEGA Down Imaging sonar transducer. It's the high-thrust freshwater configuration for the largest bass boats, walleye boats, and big-water fishing platforms.

What 112 lb / 36V means in boat sizing. 112 lb thrust at 36V is the highest standard recreational trolling motor configuration - meaningful step up from the more common 80 lb / 24V class. Sized for boats in the 25-30+ ft range where 80 lb motors don't have enough thrust to maintain confident control against wind, current, and waves. Typical applications: large bass boats with 250+ HP outboards, big-water walleye boats fishing the Great Lakes, large center consoles where the trolling motor must compete with significant wind / current loads. For smaller boats (under 24 ft), the 112 is overkill - choose the 80 or 70 lb thrust variants for appropriate sizing. For matching the motor to the boat: too small leaves you with insufficient control authority, too large drains batteries faster than needed without proportional benefit.

Why 36V vs 24V. The 36V configuration uses three 12V batteries wired in series vs the two-battery 24V configuration. Practical benefits: (1) Higher thrust capability - the 112 lb thrust requires the higher voltage to deliver. (2) Longer runtime per battery charge - the higher voltage means lower current draw for the same power, reducing voltage sag during heavy use and extending effective battery life. (3) Headroom for sustained operation - the 36V system maintains performance under sustained heavy load where 24V systems can sag. The trade-off: 36V requires three batteries vs two for 24V, adding weight (about 60-80 lb of battery weight) and bow space (three batteries take more space than two). For boats sized appropriately for 112 lb thrust, the 36V benefit outweighs the extra battery weight.

72-inch shaft and bow height. The 72-inch shaft is the standard freshwater length - matches typical bass / walleye boat bow heights of 20-26 inches above the waterline. The prop needs to be 4-6 inches below the waterline when deployed for proper thrust and to avoid surface cavitation. For taller bow heights (deep-V hulls, larger center consoles with bow heights above 26 inches), step up to the 84-inch shaft variant. The 72-inch fits the majority of typical bass and walleye boats. Measure your bow height before purchase - using the wrong shaft length causes prop cavitation at speed or insufficient submersion at rest.

Spot-Lock GPS anchoring. Spot-Lock holds your boat at any GPS position with unparalleled GPS accuracy. Set a Spot-Lock and the motor automatically adjusts thrust and direction to keep the boat within a tight position tolerance regardless of wind and current. Practical impact: when you find a productive spot (brush pile, ledge, school of fish), Spot-Lock holds the boat exactly there while you fish without anchor noise, anchor recovery, or boat drift. The Jog feature from the wireless remote moves the locked position 5 ft in any direction without disengaging Spot-Lock - essential for fine-positioning over structure without having to disengage and re-engage. The 112's substantial thrust handles Spot-Lock in heavier wind and current than smaller motors can manage - meaningful advantage for big-water fishing.

AutoPilot heading control. AutoPilot maintains a heading you set regardless of wind, waves, and current - the motor automatically corrects to keep the boat tracking the set direction. Practical use: trolling along structure, working a shoreline, drifting a known productive line - AutoPilot frees you from constant steering input and lets you focus on casting and detecting strikes. Combined with the 112's high thrust, AutoPilot works confidently even in conditions where smaller motors would struggle to maintain heading.

Wireless remote with LCD. The wireless remote includes an easy-to-read LCD screen showing motor speed, GPS function status, battery condition, and other operating data. Operate the trolling motor from anywhere on the boat - the cockpit while landing a fish, the stern while netting, mid-deck while moving between fishing positions. Critical for solo anglers and small crews where leaving the helm or fishing position to adjust the trolling motor is impractical. The remote handles all primary control functions (speed, steering, Spot-Lock activation, AutoPilot, Jog) via radio communication.

Integrated MEGA Down Imaging transducer. The Terrova 112's lower unit has a MEGA Down Imaging sonar transducer built into the motor body - no separate transducer mounting required for compatible fish finders. The MEGA DI transducer outputs MEGA-quality down-imaging sonar through the trolling motor cable. Run the cable into a compatible fish finder for high-detail bottom imagery directly below the boat as you operate. For boats with MEGA-compatible fish finders, integrated transducer mounting is meaningful - no separate transom-mount or trolling-motor-mount transducer to install, no transducer cable to run separately. For boats with non-MEGA fish finders, the transducer is still useful for general sonar functions.

Indestructible composite shaft. The shaft (main vertical tube connecting motor head at the top to the underwater motor / prop unit at the bottom) is Minn Kota's exclusive composite material - flexible enough to absorb impact without breaking, strong enough to handle propulsion loads. Minn Kota guarantees the shaft for life - if you ever break it, they replace it. The shaft is the most common failure point on trolling motors used in serious fishing (impact with submerged stumps, rocks, dock structures), so the lifetime warranty is meaningful protection. The composite material also resists corrosion in freshwater service.

Weedless Wedge 2 prop. The Weedless Wedge 2 swept-back flared-blade prop powers through freshwater vegetation (grass, weeds, hydrilla, milfoil) without the battery-draining chopping and hacking that conventional props produce when they hit vegetation. Critical for freshwater fishing where vegetation is unavoidable - the typical conventional prop stalls hard when it hits grass, drawing huge battery current to keep cutting through. The Weedless Wedge 2 slides through vegetation with minimal extra current draw.

Mobile app and compatible fish finder integration. The Terrova 112 includes Bluetooth connectivity to Apple and Android smartphones via the Minn Kota mobile app. App features: motor control from your phone, GPS map view of saved Spot-Locks and recorded paths, software updates, configuration adjustments. The motor also integrates with compatible fish finders via Ethernet networking - activate Spot-Lock from the fish finder display by tapping at a marker location, display trolling motor data (speed, battery, Spot-Lock status) on the fish finder. For boats running compatible fish finder ecosystems, the trolling motor and fish finder act as one integrated system.

Freshwater only. The Terrova 112 is the freshwater variant of the Minn Kota platform. For saltwater applications (inshore bay fishing, coastal saltwater), use the Riptide Terrova line which includes the full saltwater corrosion package (sealed electrical, anodized aluminum, sacrificial anode). Using the freshwater Terrova in saltwater destroys it within 1-2 seasons - the corrosion package isn't present. The Riptide Terrova 112 is the saltwater variant at the same 112 lb / 36V configuration.

Install and battery requirements. Plan for 4-8 hours for an experienced installer. 36V system: three 12V deep-cycle marine batteries wired in series. Battery options: AGM (Group 27 or 31) or lithium LiFePO4 (lighter weight, longer service life, premium price). Total bank capacity 270-330 Ah for AGM. Maximum amp draw at full thrust: about 52 amps from the 36V bank. Wire 6 AWG marine-grade tinned cable from the battery bank to the bow through a 60A circuit breaker. Mount the motor on the bow deck with proper backing under thin aluminum or fiberglass. Configure the wireless remote pairing per included instructions.

Warranty. Standard Minn Kota limited warranty applies to the Terrova line, typically 3 years on the motor with the lifetime composite shaft guarantee. Save the receipt. Warranty service runs through the authorized Minn Kota service network in the U.S. and Canada. Most field failures Minn Kota sees are install-related rather than motor defects - careful install delivers many seasons of trouble-free operation.
