Best GPS Trolling Motors With Spot-Lock for Bass Boats

The best GPS trolling motors with spot lock technology for bass boats are the Minn Kota Ultrex Quest for precise cable-steer control, Garmin Force Kraken for deep-water versatility and quiet operation, and Lowrance Ghost for anglers already invested in a Lowrance electronics network.

Quick comparison: the leading Spot-Lock choices

These motors are not interchangeable simply because they all hold position with GPS. Thrust, shaft length, battery voltage, mounting hardware, steering feel, and chartplotter compatibility determine whether a motor feels properly matched to your bass boat.

Specifications can vary by shaft length, generation, and regional configuration, so verify the exact part number before buying. Maximum thrust is not a direct speed rating: a boat’s hull shape, propeller, battery condition, wind, and current all affect performance.

Our picks by bass-boat situation

Best overall for active bass fishing: Minn Kota Ultrex Quest

The Ultrex Quest is the strongest all-around choice when an angler wants the immediate steering response of a cable pedal without giving up GPS-assisted functions. Its foot pedal lets you make quick corrections around docks, grass edges, and laydowns, while Spot-Lock can hold the boat over a waypoint or productive stretch.

Choose the 90-pound, 24-volt version for many typical 18- to 19-foot bass boats. The 115-pound, 36-volt version makes more sense for a heavier boat, strong current, large reservoirs, or frequent windy-water fishing. The larger system requires an additional battery and more installation space, so buying maximum thrust “just in case” can add weight and charging complexity.

The Quest is particularly attractive when the boat already uses Minn Kota-compatible accessories or a Minn Kota-compatible fish-finding system. Its main drawback is the price and the physical bulk of a high-end bow mount. General market pricing for premium motors in this class commonly falls in the roughly $2,500-$4,000 range before batteries, wiring, chargers, and installation.

Best for deep water and a Garmin electronics setup: Garmin Force Kraken

The Force Kraken is the most compelling option when shaft length is the deciding factor. Its long-shaft configurations help keep the propeller submerged when the bow rises in waves or when the motor is mounted high on a tall bass-boat bow. That extra reach can prevent intermittent prop ventilation in rough conditions.

Its wireless steering and controls create a clean installation, and its integration with Garmin chartplotters is a major advantage for anglers who mark waypoints, follow contours, or fish with a Garmin-based network. The motor is also known for low operating noise, which can matter when working shallow flats or pressured fish.

Before choosing the Kraken, measure the distance from the bow-mounted bracket to the waterline with the boat loaded normally. A long shaft is useful only when it remains practical to stow and does not interfere with the front deck, rod storage, or cover. It can also increase leverage on the mount during trailering and rough travel.

Best for Lowrance and Simrad users: Lowrance Ghost

The Lowrance Ghost is a logical head-to-head alternative to the Ultrex for anglers who use Lowrance or Simrad electronics. Its GPS anchor function, route-following features, and chartplotter integration are most valuable when the entire boat uses the same electronics ecosystem.

At 97 pounds on 24 volts and 120 pounds on 36 volts, it offers substantial thrust for bass boats that regularly face wind or current. The cable-steer layout suits anglers who want tactile foot control rather than relying mainly on a handheld remote.

Its selection is less compelling if your boat is built around Garmin or Minn Kota networking. A trolling motor can still operate independently, but cross-brand integration may be limited compared with staying within one electronics family.

How much thrust and shaft length do you need?

For a typical bass boat, use boat weight, water conditions, and expected load rather than length alone. A lightly loaded 17-foot boat used on small lakes may work well with a 24-volt motor in the 80- to 90-pound range. A heavy 19- to 21-foot boat carrying full fuel, batteries, tackle, and passengers is a better candidate for 36 volts and approximately 100- to 120-pound thrust.

• 24 volts: a practical balance for many recreational bass boats and anglers who prioritize lower weight and simpler charging.
• 36 volts: better for heavier hulls, strong wind, current, long days at high power, or frequent tournament use.
• 45-inch shaft: often suitable for lower bows and protected inland water.
• 52- to 60-inch shaft: a safer middle ground for many bass boats, especially when waves can lift the bow.
• 63 inches and longer: useful for high bows and rough water, but verify stowage clearance and mounting strength.

A simple sizing check is to measure from the proposed mounting surface to the waterline, then add enough shaft length for the propeller to remain submerged when the bow pitches upward. Allowing approximately 12 to 18 inches of submerged shaft below the waterline is a useful starting point, though the manufacturer’s installation guidance takes priority.

Spot-Lock controls: what differs on the water?

GPS anchoring is only as useful as the controls available when conditions change. All three major systems can hold a position, but their operating experience differs.

• Foot-pedal control: best for rapid heading and speed changes while casting. Cable-steer pedals generally provide the most familiar “instant” response.
• Remote control: useful from the rear deck, while netting a fish, or when making small position adjustments without taking a hand off the rod for long.
• Chartplotter control: valuable for saving locations, following contours, and combining Spot-Lock with a digital map.
• Jog or position adjustment: important when wind moves the boat just outside the productive zone. Look for controls that shift the locked position in small, predictable increments.

Spot-Lock is not a substitute for an anchor in every situation. GPS accuracy, wind gusts, prop wash, weeds, and changing current can all cause movement. Use it as a position-holding aid, keep the motor clear of swimmers and submerged hazards, and avoid assuming that a locked boat will remain perfectly stationary.

Battery planning and ownership costs

Thrust ratings do not tell you how long a motor will run. A useful estimate is:

Runtime in hours ≈ battery amp-hours × usable percentage ÷ average current draw.

For example, a 24-volt bank made from two 100-amp-hour batteries has approximately 2,400 watt-hours before losses. If the motor averages 300 watts while maneuvering—not its maximum draw—an idealized calculation gives about eight hours. Real-world runtime will be lower because batteries should not always be fully discharged, temperatures affect capacity, and wind or weeds increase load. A 36-volt system can deliver more power, but it also requires three batteries in a conventional series bank.

Budget for a correctly sized onboard charger, marine-grade cabling, circuit protection, battery trays, and professional installation if the existing wiring is undersized. Premium motor prices are only part of the ownership cost.

Durability details buyers often overlook

The parts most likely to require attention are the propeller, prop pin, sacrificial hardware, steering components, battery terminals, and mounting fasteners. Fishing line and weeds can wrap the prop shaft, while repeated beaching or contact with submerged timber can damage the propeller or lower unit.

• Rinse the motor after use in muddy, sandy, or brackish water, following the manufacturer’s guidance.
• Inspect the propeller and remove line before it reaches the seal area.
• Keep battery terminals tight, clean, and protected from corrosion.
• Check the mount and transom or deck fasteners periodically; vibration can loosen hardware.
• Stow the motor before trailering unless the specific mount and manufacturer instructions permit otherwise.
• Update compatible software and chartplotters when recommended, since GPS and networking issues can sometimes be configuration-related.

Final buying recommendation

Choose the Minn Kota Ultrex Quest if tactile cable steering is central to how you fish. Choose the Garmin Force Kraken if you need a long shaft, quiet operation, and Garmin integration. Choose the Lowrance Ghost if your boat already relies on Lowrance or Simrad electronics and you want strong thrust with cable-steer control. For a lower-complexity setup, prioritize correct shaft length and a properly sized 24- or 36-volt battery system before paying for features you will rarely use.
