Re-Attaching Boat Rubber Bumpers: A Step-By-Step Guide

Putting a rubber bumper back on a boat is a time-consuming task, but it is not difficult. The process involves removing the old bumper, cleaning the metal channel, and installing the new bumper. To remove the old bumper, you can use a heat gun to soften it and a screwdriver to pry it out gently. It is important to ensure that the metal channel is not damaged during this process. After removing the old bumper, use a screwdriver or another flat tool to clean out the grooves in the metal channel. Check if the channel is loose and replace any rivets if necessary. When installing the new rubber bumper, ensure it is at room temperature or soaked in hot water to make it more pliable. Squeeze and pinch the rubber towards its centre and press it into the bottom of the channel. Use a screwdriver to guide it into the upper channel groove.

Heat the rubber bumper

Heating the rubber bumper is an essential step in the process of putting a rubber bumper back on a boat. It is important to work on a warm day, as the rubber bumper will be more flexible and pliable. If you are working in cold weather, you can soak the rubber bumper in hot water to ensure it remains flexible.

A heat gun will be a useful tool to have when heating the rubber bumper. You can use it to warm the rubber bumper as you work, keeping it flexible and making it easier to work with. A hair dryer can also be used in a similar way to a heat gun and will be helpful in trouble spots.

When removing an old rubber bumper, heat it up to soften and loosen it. This will make it easier to pry out. When installing a new rubber bumper, heat it to make it more flexible so that it can be pressed or squeezed into the metal channel. If the boat is sitting high on a trailer, you can start by putting the top in first and then guide the bottom into the groove.

Heating the rubber bumper is a crucial step in ensuring a successful installation. It will make the rubber more pliable and easier to work with, preventing any damage to the bumper or the boat.

Pry out the old bumper

If the bumper is held in place with plastic expanding fasteners, you can try to remove the expanding pin from the centre of the fastener to preserve the fastener. However, this can be difficult, and it may be easier to simply buy new fasteners. To remove the old fasteners, you can drill out the pin, slide a putty knife or chisel under the flange and pop the fastener off, or use a small pry bar or flat-head screwdriver to slip into the gap and pry up the ridge on the pin head.

Clean the metal channel

To clean the metal channel, start by removing the rub rail end caps. You can use a wide, standard spade screwdriver to pry out the old insert. Be careful not to damage the rub rail itself. If the old insert is stiff, you may need a heat gun to help soften and loosen it.

Once the old insert is removed, clean any debris from the rub rail channel. Check for any loose screws or places where the rail may have pulled away from the cap. If necessary, rebed and tighten any loose screws securing the rail to the cap.

It is important to ensure that the metal channel is clean and free of debris before installing the new rubber bumper. This will help ensure a proper fit and prevent damage to the new bumper. Take your time and be thorough during this step to ensure a successful installation.

If the metal channel is damaged or deformed, you may need to repair or replace it before installing the new rubber bumper. It is important to address any issues with the metal channel before proceeding with the installation. This will help ensure that the new rubber bumper fits properly and can function effectively.

Additionally, it is recommended to check the condition of the screws or rivets that secure the metal channel to the boat. If they are loose or corroded, tighten or replace them as needed. This will help ensure that the metal channel is securely attached to the boat and can withstand the forces exerted during docking and trailering.

Check the metal channel for damage

Before you begin the process of putting a rubber bumper back on your boat, it is important to check the metal channel for damage. This is because the metal channel plays a crucial role in securing the rubber bumper around the boat.

Begin by inspecting the metal channel for any signs of banging or squishing. Pay close attention to the grooves in the metal channel, as these are essential for holding the rubber bumper in place. Use a small screwdriver or another flat tool to clean out the grooves and remove any debris. This step will help you identify any damage or loose parts.

Next, check if the metal channel is loose. If it is, you may need to replace a few rivets to tighten it up. Ensure that the channel is securely attached to the boat before proceeding.

Additionally, examine the metal channel for any signs of corrosion or rust. Corrosion can weaken the metal and compromise the integrity of the channel. If you notice any corrosion, take the necessary steps to treat and prevent further corrosion, such as using corrosion inhibitors or consulting a professional.

By thoroughly inspecting the metal channel for damage, you can ensure that it is in good condition and able to securely hold the rubber bumper. This step is crucial for the long-term performance and safety of your boat's rubber bumper.

Insert the new bumper

Now that you've removed the old bumper and cleaned the metal channel, it's time to insert the new bumper. Ensure that the new rubber bumper is at room temperature or warmer, as this will make it more pliable and easier to work with. If it's cold, you can soak the rubber in hot water or use a hair dryer or heat gun to warm it up.

Starting at one end of the rub rail, force the new bumper into the channel, leaving a small section extended from the end of the rub rail. You can use a screwdriver to help leverage the slot open and guide the new bumper into place. Work your way along the rub rail, uncoiling the rubber bumper as you go. A helper can make this process easier by feeding the coil and directing a heat gun at the rail to keep it flexible. Take your time and be especially careful at the corners to ensure the bumper stays tight inside the channel.

Once you've reached the other end of the rub rail, trim both ends of the bumper so that they are flush with the rub rail. Seal the ends with silicone adhesive. If necessary, drill a pilot hole in the bumper if the end cap requires a screw. Reinstall the rub rail end caps and do a final inspection to ensure the new bumper is fully seated and secure.
