Electric trolling motors are self-contained marine propulsion units that provide quiet, efficient power for precise boat control and positioning. These motors consist of an electric motor, propeller, and control system mounted on your boat's bow or transom, powered by deep-cycle marine batteries. Unlike gas outboards, electric trolling motors offer silent operation, instant throttle response, and advanced features like GPS spot-lock technology, making them essential equipment for serious anglers and recreational boaters seeking better boat control.
Whether you're stalking bass in shallow water, trolling for walleye, or simply need auxiliary power for your fishing boat with trolling motor setup, this comprehensive guide will help you choose the perfect electric motor for your needs and budget.
What Are Electric Trolling Motors and How Do They Work?
Electric trolling motors revolutionized fishing when O.G. Schmidt invented the first model in 1934 by attaching a Ford Model A starter motor to a flexible shaft with a propeller. Today's motors have evolved dramatically from that simple beginning, incorporating advanced brushless electric trolling motor technology and sophisticated control systems.
The basic operation remains elegantly simple. An electric motor sealed in a waterproof compartment drives a propeller directly mounted on the motor shaft. This submerged design prevents overheating while providing efficient thrust. Power comes from deep-cycle marine batteries, typically in 12-volt, 24-volt, or 36-volt configurations.
Modern electric trolling motors feature several key components working in harmony. The powerhead contains the electric motor and electronic controls. The composite or stainless steel shaft houses wiring and provides structural support. The lower unit protects the motor while the propeller converts rotational energy into thrust. Control systems range from simple tiller handles to sophisticated wireless remotes with GPS integration.
Types of Electric Trolling Motors
Bow Mount vs. Transom Mount
Bow-mounted motors dominate among serious anglers for good reason. Mounted on the boat's front deck, they pull rather than push the vessel, providing superior control and maneuverability. This positioning allows hands-free operation via foot pedal, keeping both hands free for fishing. Professional bass anglers universally prefer bow mounts for their precise boat positioning capabilities.
Transom-mounted motors attach to the boat's stern like a small outboard. These motors work well for trolling motors for small boats, canoes, and kayaks where bow mounting isn't practical. Hand-controlled via tiller, transom mounts offer simplicity and lower cost, making them popular for casual fishing and auxiliary power needs.
Freshwater vs. Saltwater Models
Saltwater environments demand specialized construction to combat corrosion. Saltwater trolling motors like Garmin's Force Kraken use corrosion-resistant materials, redundant systems, and sealed electronics. These models feature sacrificial anodes, stainless steel components, and advanced coatings that freshwater motors lack.
Freshwater motors cost less but won't survive saltwater exposure. The salt accelerates corrosion through electrolysis, destroying standard motors quickly. While some anglers try using freshwater motors in brackish water, the false economy usually results in premature failure and voided warranties.
Brushed vs. Brushless Electric Trolling Motor Technology
The Ghost features a brushless motor design with a powerful 120 pounds of thrust on the 36-volt option. Brushless motors represent the latest advancement in trolling motor technology, offering several advantages over traditional brushed designs.
Brushless motors eliminate the carbon brushes that create friction and wear in older designs. This results in quieter operation, improved efficiency, and longer lifespan. To produce enough torque to move heavy boats, the best saltwater trolling motors use brushless motors that draw less electricity and create more power. While brushless models cost more initially, their superior performance and durability often justify the investment for serious anglers.
How to Choose the Best Electric Trolling Motors?
Thrust Requirements by Boat Size
Selecting proper thrust ensures adequate power for boat control in various conditions. Industry guidelines recommend minimum thrust based on boat weight:
| Boat Length | Boat Weight | Minimum Thrust |
|---|---|---|
| Under 14 ft | Under 1,500 lbs | 30-40 lbs |
| 14-16 ft | 1,500-2,500 lbs | 40-55 lbs |
| 16-19 ft | 2,500-3,500 lbs | 55-80 lbs |
| 19-21 ft | 3,500-4,500 lbs | 80-112 lbs |
| Over 21 ft | Over 4,500 lbs | 112+ lbs |
Remember these represent minimums. Factors like wind exposure, current, and fishing style may require additional thrust. Many experienced anglers choose 20-30% more thrust than minimum recommendations for better performance in challenging conditions.
Voltage Options (12V, 24V, 36V)
Battery voltage directly impacts available power and runtime. Modern electric trolling motors are designed around a 12-volt, 24-volt or 36-volt brushed DC electric motor, to take advantage of the availability of 12-volt deep cycle batteries designed specifically for marine use.
Twelve-volt systems suit small boats and kayaks, providing adequate power with single battery simplicity. Twenty-four-volt systems offer a good balance for bass boats under 19 feet, doubling available power while maintaining reasonable weight. Thirty-six-volt systems deliver maximum thrust for large boats and challenging conditions but require three batteries and substantial electrical infrastructure.
Shaft Length Considerations
Proper shaft length keeps the prop submerged without excessive drag or interference. Measure from the mounting surface to the waterline, then add 20 inches minimum. Common shaft lengths include:
- 36" - 42": Small boats, calm water
- 48" - 52": Average bass boats
- 54" - 60": Larger boats, rough water
- 72" - 87": Bay boats, high freeboards
Control Options (Hand, Foot, Wireless)
Control systems significantly impact fishing effectiveness. Hand control via tiller works for basic needs but limits mobility. Foot pedals free both hands for fishing while providing precise control. Cable-driven pedals offer reliability, while electric pedals provide smoother operation.
Wireless remotes represent the pinnacle of convenience. Garmin's electronics have set the standard with the move into the forward-facing sonar era, and their wireless trolling motor controls follow suit. Key fob remotes allow control from anywhere in the boat, perfect for guides or anglers who move around frequently.
