Putting A Steering Cable On A Boat: A Step-By-Step Guide

Installing a cable steering system on a boat can be a complex process, but it's crucial to ensure the safety of everyone on board. This process involves several steps, from calculating the correct cable length to connecting the steering cables to the outboard bracket. The cable length calculation takes into account the distance from the steering wheel to the outboard motor, including the distance from the wheel to the dash, the dash to the transom, and the transom to the outboard. It's also important to consider 90-degree bends in the cable path and add extra length to accommodate cable routing. The next step is fitting the cables to the helm, which involves attaching the steering wheel, pushing the cable into the helm, locking it in place, and covering any exposed cable to prevent corrosion. The mounting bracket and steering helm are then installed, followed by the bezel cup, Woodruff Key, and steering wheel. Lubrication of the cable and tilt tube is essential, followed by bolting the connection kit to the steering cable rod and the outboard bracket. Finally, it's important to confirm the system's functionality and tighten all bolts to ensure a secure steering setup.

Calculating the length of the cable

First, you need to measure the distance between the steering wheel and the outboard motor. This distance can be divided into three parts: the distance from the steering wheel to the dash, the distance from the dash to the transom, and the distance from the transom to the outboard. For example, if these measurements are 5 feet, 4 feet, and 6 feet, respectively, your total cable length so far would be 15 feet.

Next, you need to account for any 90-degree bends in the cable's path. Each 90-degree bend creates tension and strain on the cable, so it's important to subtract 10 centimetres (or approximately 4 inches) from the total length for each bend.

Additionally, you should add 20.5 centimetres (or approximately 8 inches) to the total length to allow for any other factors, such as cable routing, and to ensure you have enough slack in the cable.

If you have the old cable available, you can determine the length of the new cable by measuring the cable jacket length and adding 0.56 metres. Then, multiply this metric measurement by 3.28 to get the length in feet.

It's important to note that some cables are measured in feet, while others are measured in metres. The length of the cable can also vary depending on whether you have a stationary motor or a movable one. For boats with a stationary motor, you don't need to add extra length to account for the motor's movement.

Finally, when ordering the cable, it's recommended to round up the calculated length to the nearest foot, as steering cables are typically available in multiples of one foot.

Fitting the cables to the helm

Temporarily attach the steering wheel:

First, secure the steering wheel to the helm temporarily. This makes it easier to fit the steering cables as the wheel provides a larger surface area to work with.

Push the steering cable into the helm:

Thread the steering cable through the hole in the helm and push it in until it catches. Then, turn the wheel to pull the cable through the helm and out the other side.

Lock the cable in place:

Once the cable is through the helm, use the provided bolt to lock it in place. Tighten the bolt securely, but be careful not to overtighten, as this can damage the cable.

Cover any exposed cable:

Use the supplied cover to protect any exposed cable from corrosion. Corrosion can cause reduced performance and even failure of the steering system, especially in saltwater environments.

Cut the hole for the mounting bracket:

Use the printed template included with the bezel kit to cut the hole for the mounting bracket. This will ensure the hole is correctly positioned and sized.

Fix the mounting bracket in place:

Secure the mounting bracket using the provided nuts and bolts. The bracket provides a stable base for the steering helm. Before tightening, apply Duralac to the bolts to prevent electrolytic corrosion due to contact with dissimilar metals.

Push the steering helm through the bracket:

Push the steering helm through the bracket and attach it securely with bolts. The helm is the central point of the steering system, so ensure it is firmly attached to the boat.

By following these steps, you will have successfully fitted the cables to the helm, bringing you one step closer to a safe and functional steering system for your boat.

Steering wheel attachment

Now that you have calculated the cable length, you can begin the process of attaching the steering wheel.

Firstly, temporarily attach the steering wheel to the helm. This will make it easier to fit the steering cables as the wheel provides a larger surface area. Next, push the steering cable into the helm by threading it through the hole and pushing it until it catches. Then, turn the wheel to pull the cable through the helm and out the other side.

Once the cable is through, use the provided bolt to lock it in place. Ensure that you tighten the bolt securely, but be careful not to overtighten as this can damage the cable. Cover any exposed cable with the supplied cover to prevent corrosion, especially in saltwater environments.

Now, cut the hole for the mounting bracket using the template provided with the bezel kit. This will ensure the hole is correctly positioned and sized. Fix the mounting bracket in place using the provided nuts and bolts, and remember to use Duralac on the bolts to prevent electrolytic corrosion.

Push the steering helm through the bracket and attach it with bolts. This will serve as the central point of your steering system, so ensure it is securely attached. Screw the bezel cup onto the steering helm shaft to provide a finished look and protect the helm.

Place the Woodruff Key, a small half-moon-shaped piece of metal, into the slot on the helm shaft. This ensures the steering wheel is correctly aligned and won't slip or move. Slot the steering wheel over the helm shaft and Woodruff Key, ensuring it is aligned correctly.

Finally, secure the steering wheel in place with the locknut and tighten thoroughly with a wrench. A loose steering wheel can be dangerous and lead to a loss of control, so ensure the locknut is drawn correctly. Finish by fixing the trim cap over the steering wheel for a finished look and added protection.

Cover exposed cables

Exposed cables on a boat can be dangerous and lead to losing control of the vessel. Therefore, it is essential to cover any exposed cables to protect them from corrosion and ensure they last as long as possible.

Choose the Right Cover

Select a cover that is specifically designed for steering cables in a marine environment. This cover should be made from corrosion-resistant materials and be able to withstand the harsh conditions of saltwater and sun exposure. Make sure the cover is compatible with the type and size of your steering cable.

Clean the Cable

Before installing the cover, ensure that the steering cable is clean and free of any debris, grease, or corrosion. You can use a wire brush or a mild detergent to clean the cable thoroughly. This step is crucial as it will help the cover adhere better and create a stronger barrier against corrosion.

Install the Cover

Follow the instructions provided with the cover for proper installation. Typically, you will need to slide the cover over the exposed cable, ensuring that it fits snugly and securely. Make sure there are no gaps or loose areas where water or salt can infiltrate. Secure the cover using cable ties or clamps if necessary.
