Selecting the right trolling motor involves considering several factors, including water type, shaft length, thrust requirements, power consumption, and advanced features. Here's a comprehensive guide to help you make the best choice.
Freshwater vs. Saltwater
Saltwater motors come with corrosion-resistant coatings and enhanced seals to protect against harsh marine environments. If you primarily fish in saltwater, invest in a dedicated saltwater motor to ensure longevity and reliability.
Shaft Length
The standard shaft length is 42 inches. To determine the appropriate length for your boat, measure the distance from where the shaft is mounted to the waterline and add 16 inches (for MotorGuide) or 20 inches (for Minn Kota). For rough waters, add an additional 8 inches to keep the propeller submerged during waves and boat movements.
Thrust Requirements
Thrust is measured in pounds and determines the power needed to maneuver your boat. As a general rule, 72-75 pounds of thrust equate to approximately one horsepower or 746W of electrical power. Trolling motors are available in 12V, 24V, and 36V versions, with higher voltages providing greater thrust. Maximum thrust at different voltages is approximately:
-
12V: Up to 55 lb.
-
24V: Up to 80 lb.
-
36V: Over 100 lb.
For optimal performance, we recommend 5 lb. of thrust per 200 lb. of the boat's total weight.
Mounting Options
Bow-Mount Motors
Bow-mounted motors provide excellent maneuverability, making them ideal for open-bow boats and bass boats. A spring-loaded mount, like the Minn Kota BowGuard 360, helps prevent damage by allowing the motor to swing away upon impact.
Transom-Mount Motors
Transom-mounted motors are great for anglers operating from the back of the boat or for sailboat owners using a trolling motor as an auxiliary engine. Adjustable brackets allow for varying angles and depths to ensure proper immersion.
Power Consumption
Understanding power consumption helps determine battery requirements. A 12V motor drawing 60A consumes approximately 720W. The higher the voltage, the greater the thrust. Choose a 24V or 36V system for longer trips or if you fish in demanding conditions.
Advanced Features
Modern trolling motors offer convenient features such as:
-
Autopilot and route storage: Navigate your most productive fishing spots hands-free.
-
Bluetooth connectivity: Control your motor remotely via a smartphone or dedicated remote.
-
Integrated sonar and fishfinder compatibility: Minn Kota motors with Humminbird’s MEGA Down Imaging enhance fishing efficiency.
Trolling Motor FAQs
How do I maintain my trolling motor?
Rinse with fresh water after use, check for debris, lubricate moving parts, and inspect electrical components for corrosion.
Can I use a freshwater trolling motor in saltwater?
It’s not recommended, as freshwater motors lack corrosion-resistant coatings. If used in saltwater, rinse thoroughly afterward.
Tiller vs. Foot Pedal: Which is better?
-
Tiller handle: Simple and direct control.
-
Foot pedal: Hands-free operation, great for fishing.
Can I use a trolling motor on a kayak or canoe?
Yes, but ensure the thrust rating matches your boat’s size. Opt for lightweight, compact models to avoid excessive weight.
How do I calculate battery life?
Divide the battery’s amp-hour rating by the motor’s amp draw. Example: A 100Ah battery powering a 20A motor lasts about 5 hours.
Can I charge my trolling motor battery with a solar panel?
Yes, but ensure you use a high-output solar panel with a charge controller to prevent overcharging.
Best way to store a trolling motor during the off-season?
Remove, clean, and store in a dry, cool place. Disconnect the battery and charge it periodically.
Can I use a trolling motor in weedy areas?
Yes, but check for debris around the propeller to avoid overheating or damage. Some motors feature "weedless" propellers.
Safety precautions when using a trolling motor?
Ensure proper mounting, carry spare fuses, and avoid extremely shallow or rocky areas to prevent damage.
Can I retrofit my boat with a trolling motor?
Yes, but consider mounting location, battery capacity, and space for additional batteries.
