Trolling Motor Propeller Selection and Replacement Guide

Trolling motors are an essential part of any angler’s arsenal. These devices provide watercraft with a quiet, electric-powered propulsion system for access to estuaries, bays, and backwaters, teeming with fish.

However, trolling motor efficiency depends largely on its propeller’s design and performance. Explore the various trolling motor propellers and learn when it’s time to buy a trolling motor propeller replacement for a better fishing experience.

Two-Blade vs. Three-Blade

When it comes to choosing the right trolling motor propeller, the number of blades can make a difference in your angling experience. The two most common types of trolling motor propellers are two-blade and three-blade. Here’s a breakdown of the primary differences to help you select the perfect replacement for your trolling motor:

Weed-Cutting Abilities

If you frequently fish in weed-infested waters or submerged grass beds, a three-blade propeller is ideal. With its extra blades, it excels at catching and trapping aquatic vegetation, preventing it from tangling around the propeller shaft and hindering motor performance.

Two-blade propellers struggle to cut through weeds effectively and are more likely to get entangled in aquatic plants, which means you’ll need to stop more often to clean off your motor.

Steering Stability

For stable steering, especially at higher speeds, three-blade help maintain a straight course, reducing the need for constant adjustments.

Two-blade propellers require frequent steering adjustments when you are going fast. However, if you are fishing in areas with high winds or strong currents, a two-blade propeller offers better stability due to its increased thrust.

Power and Thrust

Three-blade propellers offer less power compared to most two-blade versions due to increased drag from the additional blade. They are commonly used with larger motors on larger boats.

Two-blade propellers typically have a broader diameter than three-blade models, which provides more power and thrust, making them ideal for handling high winds and strong currents. They also allow you to run the motor on a lower setting while still maintaining a similar thrust to a three-blade propeller on a higher setting.

Top Picks for Three-Blade and Two-Blade Replacement Propellers

When selecting between three-blade and two-blade propellers, consider the specific conditions you’ll encounter on your angling adventures to make the best choice for your trolling motor.

How to Replace a Trolling Motor Propeller?

Over time, it’s common for trolling motor propellers to experience wear and tear or sustain damage from hitting obstacles, fishing lines, or weeds under the water. Replacing a propeller is a cost-effective alternative to changing the entire motor, and it’s a relatively straightforward process that you can do yourself with the right tools and steps.

Before you start the replacement process, gather the following tools:

• Screwdriver
• Wrench
• Replacement propeller
• Propeller nut and pin

• Safety first: Before you start, ensure that your trolling motor is turned off and disconnected from the power source. This is critical to avoid any accidents during the replacement process.
• Access the propeller: Locate the propeller on your trolling motor, typically positioned just below the motor head. You might need to remove any covers or guards that obstruct access.
• Remove the old propeller: Loosen and remove the propeller nut and pin using a wrench or pliers. These components hold the propeller in place on the motor shaft. Gently slide off the old propeller.
• Install the replacement propeller: Slide the new propeller onto the motor shaft, ensuring it aligns properly. Make sure the hub of the propeller fits snugly onto the motor shaft.
• Secure with nut and pin: Reattach the propeller nut and pin, and tighten them securely. This step is crucial to ensure that the propeller is firmly in place and doesn’t come loose during operation. However, avoid overtightening; this can bend the drive pin and damage the prop.
• Test the motor: Before heading out onto the water, test your trolling motor to ensure the replacement propeller is functioning correctly. Check for any unusual noises or vibrations.

Maintenance Tips for a Trolling Motor Propeller

To keep your trolling motor propeller in top condition and ensure the longevity of your equipment, consider these maintenance tips:

• Regular cleaning: Clean your trolling motor propeller after each use to remove debris, weeds, fishing lines, and algae. This prevents unnecessary strain on the motor and maintains its efficiency.
• Inspection for damage and wear: Regularly inspect the propeller for signs of damage, wear, or bent blades. Replace any damaged parts promptly to avoid performance issues.
• Lubrication: Apply a small amount of lubricant to the propeller nut and pin to prevent rust and make future replacements easier.
• Storage: When not in use, store your trolling motor with the propeller in a safe and dry location to prevent corrosion.
• Regular service: Schedule regular maintenance for your trolling motor, including a thorough check of the propeller, with a professional technician if you’re not comfortable performing maintenance tasks yourself.
