Replacing A Boat Winch: A Step-By-Step Guide For Beginners

Boat winch straps are important for anchoring your boat and making it easier to hoist the boat out of the water. Over time, winch straps can deteriorate due to exposure to the elements, heavy weight, wear, and pressure. Luckily, replacing a winch strap is a relatively easy and inexpensive task that can be done with just a few tools. In this article, we will provide a step-by-step guide on how to replace a boat winch, ensuring the safety and security of your boat.

Choosing a new strap

Durability:

You want a strap that can withstand heavy weights, wear and tear, and all weather conditions. Look for straps made from durable materials like polyester silk webbing or other soft, anti-scuff fabrics. This will ensure that the strap doesn't damage your boat or cause discomfort to your hands during use.

Load Capacity:

Choose a strap with a maximum breaking load at least 20% greater than the weight of your boat. This is crucial for safety reasons. Check the working load capacity of your winch, usually stamped on the winch or available from the manufacturer, and select a strap with a strength rating at or above that of the winch. Ensure both the strap and winch are rated for the weight of your boat.

Length and Width:

Straps come in various lengths and widths, and you need to choose one that fits your winch and trailer correctly. The length will depend on the length of your trailer, but make sure it's not too long or too short. The width is typically 2" or 3", and you should ensure it matches the groove size in your winch.

Compatibility:

Ensure that you choose a strap compatible with your winch type. Winches are designed for use with specific types of straps, such as webbing, rope, or cable. Check the drum width and diameter of your winch to determine the correct type of strap. Webbing-strap winches, for example, typically have a drum width of 2" or wider and a drum diameter of less than 1 3/4".

Cost:

Replacement straps are typically inexpensive, ranging from $20 to $30, or even $24.97 for the Rhino USA Boat Winch Strap with Hook, which comes with a lifetime warranty.

By considering these factors, you can choose a new strap that is safe, durable, and compatible with your boat winch and trailer.

Removing the old strap

Removing the old winch strap is a simple process, but it requires careful attention to ensure it is done correctly. Here is a detailed guide on how to remove the old strap from your boat winch:

Firstly, begin by unwinding the old strap. This is a crucial first step as it allows you to access the winch gear bolts and begin the removal process. Take care when unwinding the strap to avoid getting your fingers caught, especially if the strap is under tension. Once the strap is completely unwound, you can move on to the next step.

The next step is to disconnect the winch gear bolts. Using your wrench, loosen and remove the bolts that hold the old strap in place. You may need to use a product like WD-40 if the bolts are resistant due to corrosion. It is important to take your time with this step to ensure that the bolts are properly loosened and removed.

After removing the bolts, the old strap should easily slide off the screws. If the strap is too old or damaged, you may need to use a utility knife or a box cutter to cut it off the screws or the anchor bolt. Be cautious when handling sharp tools and ensure that you do not damage any other components of the winch.

Once the old strap is removed, take the opportunity to inspect the winch for any signs of corrosion or damage. Pay close attention to the central bolt and the winch cage. If the bolt is twisted or corroded, it is recommended to replace it with a new one. Similarly, if the winch cage shows signs of corrosion, clean it and consider spraying some cold galvanizing to protect it.

By following these steps, you will successfully remove the old strap from your boat winch. Remember to take your time, work carefully, and inspect all components for any damage or corrosion. Ensuring that your winch is in good condition is crucial for the safety and security of your boat.

Preparing the new strap

Once you have checked that the new strap is the correct size and strength, you can begin to install it. Position the new strap where the old strap was, by the screw openings, and slide in the winch strap screw. Then, connect and secure the winch strap bolt in place. Reconnect the winch gear and bolt to their original position. If you have some marine grease, you can apply a small amount to the winch gears to ensure they turn smoothly.

Now, you can begin to wind the new strap onto the winch drum. Ensure that the strap is wound neatly, lying flat with no twists, creases, or folds. Keep the strap tight, with no slack, as you slowly reel it on. Once the strap is wound, hang the hook onto the boat's ring and wind it until it is tight.

Reattaching the winch gear

Now, you will need an assistant to help. Have them hold the remaining part of the strap tightly, with no slack, as you slowly reel it on. Ensure that the strap is wound on neatly, with no twists, creases, or folds. Once you have finished, snap the new strap's hook to the boat's bow eye.

You have now successfully replaced your boat winch strap and reattached the winch gear. Well done!

Lubricating the winch

Firstly, it is important to clean the winch before lubricating it. Use a mild solvent like mineral spirits to clean the parts, especially if your winch has plastic components. Ensure all parts are completely dry before applying any lubricant.

You will need two types of lubricant: winch grease and oil. For the winch grease, opt for a name-brand product that is specifically formulated for winches. As for oil, any lightweight oil will work. However, it is recommended to use a product like Harken OneDrop.

When applying the grease, remember that less is more. Apply a light coat of grease to the main axle of the winch, the gears, and the roller bearings. Use your fingers to massage the grease into the gear races.

For the winch pawls, use oil instead of grease. Apply a single drop of oil to each pawl, ensuring they move smoothly with a "snap." While lubricating the pawls, inspect the springs and ensure they have good tension.

By following these steps and using the correct lubricants, you will help ensure the smooth and efficient operation of your winch, reducing friction and wear on the components.
