Choosing the right trolling motor is crucial for a successful fishing trip. One of the most important factors to consider when selecting a trolling motor is the shaft length. A shaft that’s too short won’t provide enough clearance, while one that’s too long can be cumbersome and potentially damage your boat. This guide provides a step-by-step process to accurately measure your trolling motor shaft length, ensuring a perfect fit for your boat and maximizing your fishing experience.
Understanding Trolling Motor Shaft Length and Types
Before we dive into the measurement process, it’s essential to understand the different types of trolling motor shafts and why correct length is crucial. The shaft length is the distance from the bottom of the motor housing to the top of the prop. Incorrect shaft length can lead to several problems:
- Insufficient clearance: A short shaft might hit the bottom of your boat, leading to damage or hindering operation. This is especially critical in shallow waters.
- Unnecessary drag: A long shaft can increase drag and reduce the efficiency of your trolling motor, significantly impacting battery life.
- Difficult maneuvering: An excessively long shaft can also interfere with maneuvering, particularly in tight spaces.
There are two main types of shafts:
- Extendable shafts: Offer flexibility, allowing adjustments based on water depth and boat type. Measuring these requires careful attention to both the fully extended and retracted lengths.
- Fixed shafts: Come in a variety of predetermined lengths. Careful measurement is crucial to select the correct length initially.

Step 1: Preparing for Measurement
Accurate measurement requires careful preparation. Here’s what you need to do:
- Clean the Transom: Ensure your boat’s transom is clean and free of any debris or obstructions that could interfere with the measurement.
- Consult Your Boat’s Manual: Your boat’s manual often provides recommendations for minimum and maximum trolling motor shaft length. Refer to this as a helpful guideline.
- Gather Your Tools: You’ll need a measuring tape, a pencil, and preferably a helper.
Step 2: Measuring Your Transom Height
This is the most critical step. Incorrect measurement here will lead to an incorrect shaft length.
- Locate the Mounting Location: Determine where your trolling motor will be mounted on your boat’s transom.
- Measure from the Bottom: Using your measuring tape, measure the vertical distance from the bottom of the boat (waterline) to the proposed mounting point on the transom. Consider the average waterline depth for your typical fishing location.
- Add the Desired Clearance: Add an extra 2-4 inches to account for desirable clearance between the prop and the bottom of the boat. This ensures you have enough space even in undulating water conditions.
- Record Your Measurement: Write down this total measurement carefully; this is the approximate shaft length you need.
Step 3: Determining the Final Shaft Length & Considerations
- Account for Motor Housing: Remember to consider the height of the motor housing when selecting your trolling motor. The total shaft length will be the measurement from Step 2 plus the motor housing. Check the specifications provided by the manufacturer.
- Transom Thickness: The transom’s thickness will influence the overall install. Account for this.
- Consider Your Fishing Style: The type of fishing you do (deep-water trolling or shallow-water fishing) should influence the final shaft length and whether an extendable shaft would be beneficial.
Choosing the Right Trolling Motor Shaft Length: A Case Study
Let’s say you measured a total of 20 inches from the waterline to your desired mounting point, plus 3 inches for clearance. This gives you 23 inches as a target length. However, your chosen trolling motor has a 5-inch motor housing height. Therefore, you would need a 28-inch shaft (23 inches + 5 inches). Always double-check the manufacturer’s specifications for accurate total length.
Common Mistakes to Avoid When Measuring Trolling Motor Shaft Length
Several mistakes can lead to an incorrectly sized trolling motor. Avoid these pitfalls:
- Neglecting Waterline Variation: Water levels fluctuate, so consider average water depths and account for potential variation.
- Ignoring Motor Housing Height: Failing to account for the motor housing height leads to a significant error in the final shaft length.
- Insufficient Clearance: Too little clearance can lead to damage to the prop and the boat.
Trolling Motor Shaft Length: Frequently Asked Questions (FAQs)
Q1: Can I use a shorter shaft than recommended? A: No, using a shorter shaft than recommended risks damage to your boat and the motor itself. It will limit your operational depth.
Q2: What happens if I use a longer shaft than needed? A: While not as immediately damaging as a short shaft, it will increase drag and reduce efficiency, impacting battery life and potentially hindering performance.
Q3: How do I measure the shaft length on an extendable trolling motor? A: Measure both the fully extended and fully retracted lengths. Pay close attention to the manufacturer’s instructions.
Q4: Where can I find more information about trolling motors? A: Consult reputable websites like [Link to Minn Kota website] and [Link to MotorGuide website] for detailed information on their motor specifications and installation guides.
