How To Measure a Teleflex Steering Cable: A Step-by-Step Guide
Accurately measuring your Teleflex steering cable is crucial for ensuring a proper fit and smooth operation of your boat’s steering system. This guide will provide a definitive method for determining the correct length, preventing costly mistakes and maximizing your boating experience. Knowing how to measure a Teleflex steering cable correctly will save you time and money in the long run.
Understanding the Importance of Accurate Measurement
Replacing a steering cable isn’t just about grabbing a new one; it’s about ensuring your vessel’s safety and maneuverability. An incorrectly sized cable can lead to:
- Difficult steering: Too short, and it binds; too long, and it’s sloppy.
- Premature wear and tear: Undue stress on the cable and connected components.
- Potential system failure: In extreme cases, a poorly fitted cable can fail, leading to loss of steering.
Taking the time to measure a Teleflex steering cable accurately is therefore essential for optimal performance and peace of mind.
Step-by-Step Guide: Measuring Your Teleflex Steering Cable
The most reliable method for measuring your existing cable or determining the necessary length for a new installation involves measuring the cable housing and adding a standard allowance. Here’s how to measure a Teleflex steering cable, step-by-step:
-
Identify the Cable Type: Teleflex and similar steering cables typically have a part number stamped on the cable housing. Note this if possible, as it may provide information on the cable’s length and specifications.
-
Measure the Cable Housing: This is the crucial step. Use a measuring tape to record the length of the outer cable housing. Start from the helm connection point (where the cable enters the helm) and extend to the engine connection point (where the cable connects to the steering linkage on the engine). Make sure you are measuring the cable housing alone, not including any exposed core wire. Extend the measuring tape straight and avoid following the bends if you have it removed from the boat, to get a precise value.
-
Add the Helm and Engine Allowance: This accounts for the internal travel of the steering cable and the space needed for connections. Teleflex cables commonly use an 18-inch allowance. Add this 18 inches to your housing measurement.
-
Round Up to the Nearest Foot: Steering cables are typically sold in one-foot increments. Round your total measurement up to the nearest whole foot to determine the correct cable length to order.
-
Verify Your Measurement: If possible, compare your calculated length with any existing markings on the old cable or the boat’s specifications.
Common Mistakes to Avoid When Measuring
Even with a careful approach, mistakes can happen. Here’s what to avoid when you’re figuring out how to measure a Teleflex steering cable:
- Measuring the Core Wire Only: The core wire extends beyond the housing, and its length is irrelevant for determining the cable size. Always measure the cable housing.
- Ignoring the Allowance: Forgetting to add the 18-inch allowance will result in a cable that is too short.
- Measuring in Bends: Measure in a straight line, even if the cable naturally bends when installed. Don’t take the measuring tape following the bends.
- Assuming All Boats Are the Same: Even boats of similar size and type can have different steering cable requirements. Always measure to be sure.
- Using Old Cables as a Guide: If your old cable was installed incorrectly or has been stretched, it’s not a reliable reference.
Alternative Measurement Methods (If Cable is Still Installed)
If you cannot remove the cable to measure it directly, you can approximate the length by tracing the cable’s path with a flexible measuring tape. Run the tape from the helm to the engine connection, following the exact route of the cable. Then, add the 18-inch allowance and round up to the nearest foot. This method is less precise but can be useful as a backup.

Choosing the Right Cable Type
Besides length, ensure you select the correct cable type and construction. Consider factors like:
- Cable Diameter: Heavier boats or those with larger engines may require a larger diameter cable.
- Core Type: Standard, low-friction, and no-feedback cables offer varying levels of steering ease.
- Material: Stainless steel is the most common and durable option.
| Cable Type | Application | Benefits |
|---|---|---|
| Standard Cable | Smaller boats, lower horsepower | Economical, reliable |
| Low-Friction Cable | Larger boats, higher horsepower | Reduced steering effort, smoother operation |
| No-Feedback Cable | Outboard motors with high torque | Prevents engine torque from affecting steering, enhanced safety |
Frequently Asked Questions
How accurate do I need to be when measuring?
Accuracy is critical. Aim for a precise measurement of the cable housing within half an inch. Rounding up to the nearest foot will accommodate any slight discrepancies. A cable that is off by several inches can cause significant steering problems.
What is the standard allowance for a Teleflex steering cable?
The standard allowance is 18 inches (457mm). This accounts for the cable’s internal travel and connection points at the helm and engine. Always remember this crucial step when considering how to measure a Teleflex steering cable.
Can I use a shorter or longer cable than recommended?
Using a shorter cable is strongly discouraged. It will create undue stress on the system, potentially leading to failure. A slightly longer cable (within one foot) is generally acceptable but can result in sloppier steering. Aim for the exact length or slightly longer, if unsure.
What tools do I need to measure a steering cable?
You’ll need a measuring tape (preferably a flexible one), a pen and paper for recording measurements, and potentially a flashlight for better visibility in tight spaces.
How do I measure the cable if it’s completely broken?
If the cable is broken, carefully piece together the outer cable housing and measure its length. Then, add the standard 18-inch allowance and round up to the nearest foot. If too damaged to piece together, the flexible measuring tape following the path within the boat might be the only alternative.
What if I’m replacing a hydraulic steering system with a mechanical cable system?
This is a significant change. You’ll need to measure the distance from the helm to the engine and consult with a marine technician to determine the appropriate cable length and compatibility with your boat.
Is it safe to use a used steering cable?
Using a used steering cable is generally not recommended. Steering cables are subject to wear and tear, and a used cable may have hidden damage. It’s always best to install a new cable for safety and reliability.
What if the existing cable has no markings?
If there are no markings, you’ll need to rely on careful measurement. Follow the steps outlined above, paying close attention to the cable housing length and the 18-inch allowance.
Can I measure the cable while it’s still connected to the engine?
It’s possible, but more difficult. Disconnecting the cable allows for a more accurate measurement. If you cannot disconnect it, carefully measure the cable housing from the helm connection to the engine connection as precisely as possible.
What happens if I order the wrong size cable?
If you order the wrong size cable, you’ll need to return it and order the correct length. Attempting to force a too-short cable will damage the system, and using a too-long cable will compromise steering performance.
Where can I purchase Teleflex steering cables?
Teleflex steering cables are widely available at marine supply stores, online retailers, and boat dealerships. Ensure you purchase from a reputable source to guarantee quality and compatibility.
How do I know if my steering cable needs replacing?
Signs of a worn-out steering cable include stiff or jerky steering, excessive play in the wheel, corrosion on the cable, and difficulty turning. Regular inspection is essential. Addressing these issues promptly, after you how to measure a Teleflex steering cable, will ensure a safe and enjoyable boating experience.
