Step-by-Step Guide to Shorten a Trolling Motor Shaft

If you’re looking to optimize your boating setup, shortening the length of a trolling motor shaft can be a practical solution. With a few simple steps, you can successfully modify the shaft to improve efficiency and functionality. Follow this step-by-step guide for clear instructions on how to adjust the length of your trolling motor shaft.

Step 1: Unplug and Remove the Trolling Motor Head

The first step is to unplug the power source and remove the head of the trolling motor. Unscrew the four Phillips screws and the 3/16″ machine screw that secure the head to the shaft. Set the head aside for now.

Step 2: Measure and Tape the Desired Cut Line

Use masking tape to mark the desired cut line on the shaft. It’s recommended to place a second wrap of tape 1/2″ below the cut line to serve as a guide during the cutting process.

Step 3: Insert Copper Pipe to Protect the Wiring

To protect the electrical wires inside the shaft, insert a short length of 1/2″ copper pipe with a .650″ inner diameter. Make sure to mark the depth of the cut before inserting the pipe. This will prevent any damage to the wires during the cutting process.

Step 4: Cut and File the Excess Shaft

Using a hacksaw with a fine-tooth blade, carefully cut the excess shaft off along the marked cut line. Once the cutting is complete, use a hand file to clean up the cut edge, ensuring a smooth and even surface.

Step 5: Drill Holes and Reattach the Trolling Motor Head

Mark the depth of the old mounting screw on the tape and ensure proper alignment of the head with the motor. Use a pin punch to mark the hole positions, then drill two 3/16″ holes through the shaft. Remove the copper pipe and clean up the holes. Bolt the head back on and shorten the wires as needed. Reattach the drive wires using yellow female 1/4″ spade clips.

Step 6: Reassemble and Verify

Reassemble the trolling motor, making sure everything is securely fastened. Verify the alignment of the head with the motor and ensure smooth and proper functionality. The shorter shaft length should provide easier stowing and improved performance.

By following these step-by-step instructions, you can successfully modify the length of your trolling motor shaft. Remember to take necessary precautions to protect the wiring inside the shaft and ensure proper alignment when reassembling the trolling motor. Enjoy the benefits of a customized and efficient trolling motor setup.

Tips for a Successful Modification

When it comes to shortening a trolling motor shaft, there are a few important tips to keep in mind to ensure a successful modification without damaging the wiring. Follow these guidelines to make the process easier and more efficient:

1. Protect the Wiring

One of the main concerns when shortening a trolling motor shaft is the potential risk of damaging the electrical wires inside. To avoid this, use a wooden dowel as a buffer between the saw blade and the wires. This will provide a protective barrier and minimize the chances of any unintentional cuts or damage.

2. Accurate Measurements

Prior to making any cuts or drilling holes, it is crucial to take accurate measurements and make precise markings. This will ensure that the shortened shaft aligns properly with the motor head and functions correctly. Double-check all measurements to avoid any mistakes or misalignments that could impact the overall performance of the motor.

3. Clean Up the Edges

After cutting the shaft, it is important to clean up the edges to prevent any sharp or jagged parts. Use a hand file to smooth out the cut edge, ensuring a clean and safe finish. This will not only improve the aesthetic appearance of the modified shaft but also minimize the risk of injury when handling or stowing the motor.

4. Reassemble and Secure

Once the modification is complete, reassemble the trolling motor and ensure all components are securely fastened. Check that the head is aligned properly with the motor and that all connections are tight. Take the time to verify that everything is in working order before using the motor to avoid any potential issues or malfunctions.

By following these tips, you can successfully modify the length of a trolling motor shaft without damaging the wiring and achieve a more optimized boating experience. Remember to prioritize safety, accuracy, and proper alignment throughout the process to ensure the best results.

Benefits of Shortening a Trolling Motor Shaft

Modifying the length of a trolling motor shaft offers numerous advantages for boaters looking to optimize their setup. Shortening the shaft not only improves functionality but also enhances boating efficiency in various ways.

Better Fit and Easier Stowing

By shortening the trolling motor shaft, you can achieve a more comfortable fit on your boat. This customized adjustment ensures that the motor is properly positioned and easier to handle. Additionally, a shorter shaft allows for effortless stowing, making it convenient to store and transport the motor when not in use.

Reduced Risk of Obstacles

A shortened shaft significantly decreases the risk of hitting obstacles in shallow waters. When the motor is closer to the water surface, there is less chance of it colliding with rocks, submerged debris, or other hazards. This not only protects the motor from potential damage but also enhances boating safety.

Improved Efficiency

Shortening the trolling motor shaft can greatly improve overall boating efficiency. The reduced length reduces drag and resistance, allowing the boat to move through the water more smoothly. This translates to better performance, faster speeds, and increased fuel efficiency. With a modified shaft, you can maximize your boating experience without compromising on power or speed.

In addition to these benefits, shortening a trolling motor shaft can also save you money. Longer shaft models may be harder to find and more expensive, making a modified shaft a cost-effective alternative. By tailoring the length to your specific needs, you can enjoy a customized and efficient trolling motor setup that enhances your boating experience.
