Replacing Windows On Your Crestliner: A Step-By-Step Guide

Maintaining a boat is no easy task, and replacing a window on a Crestliner boat is a complex process. The first step is to remove the existing window, which usually involves unscrewing trim rings and applying force to push the window out. It is important to take accurate measurements for the new window and ensure the hole is clean. The new window should be test-fitted, and any necessary adjustments, such as shimming, should be made. Finally, the new window can be installed by applying seal tape, misting the perimeter with water, and screwing the window into place.

Removing the existing windows

Clamp-Style Windows

The most common type of window installation is the clamp-in style. To remove this type of window, start by removing the screws on the trim ring, both on the inside of the boat and on the trim ring itself. This will allow you to push the window out of the opening from the inside. Make sure to apply force carefully without overdoing it to avoid damage or injury.

Releasing the Sealant

Outside the boat, there is usually sealant found under the window flange. To remove this, use a thin putty knife and work your way around the flange. Start by selecting a corner of the window and working the flange loose. Once the corner is loose, push it out of the hole. Be careful not to damage the flange or the surrounding boat structure.

Removing Residual Sealant

After removing the window, carefully remove any residual sealant that is stuck to the outside wall. This step is important to ensure a clean surface for the new window installation. Use a suitable solvent or scraper to remove the sealant without damaging the boat's exterior.

Taking Measurements

Before purchasing new windows, it is crucial to take accurate measurements of the window openings. Clean up the holes to ensure there is no debris that could interfere with the measurements. If possible, try to obtain the original line drawings from the boat builder or contact them for specific measurements if they are still in business. Take measurements for both the length and width of the holes to determine the size of the new windows. Double-check the measurements for accuracy before placing your order.

Preparing for Installation

Now that the old windows are removed and you have the measurements for the new ones, you can prepare for the next steps. Gather all the necessary tools and materials, including the new windows, seal tape, a spray water bottle, screws provided with the new windows, and any other recommended supplies. It is also a good idea to have someone assist you during the installation process, especially if your boat has larger windows.

Measuring for the new windows

Measuring for new windows is a crucial step in the window replacement process. Here are some detailed instructions to ensure accurate measurements for your Crestliner boat's new windows:

Clean the Window Hole:

Before taking any measurements, it's essential to clean the window hole thoroughly. Remove any residual sealant or debris left from the previous window to ensure an accurate measurement.

Determine the Window Type:

Crestliner boats may have different window types, such as clamp-style or frameless windows. Understanding the window type will help you measure correctly and choose the right replacement.

Measure the Length and Width:

Use a measuring tape to determine the length and width of the window hole. Measure the distance between the inside edges of the window frame or opening. Ensure you measure at the narrowest point of the opening to guarantee the new window will fit snugly.

Check for Original Drawings:

Before finalising your measurements, it's worth checking if the original line drawings from the boat builder are available. Contact the boat manufacturer or dealer to see if they can provide these drawings, which can offer precise dimensions for your window replacement.

Measure Multiple Times:

To ensure accuracy, it's recommended to measure the window hole several times. Double-checking your measurements will help prevent costly mistakes when ordering new windows.

Consider the Thickness of the Wall:

When measuring, keep in mind that the thickness of the wall at the opening should be relatively consistent. This consistency is necessary for the trim ring to clamp the new window securely.

Account for Clearance:

The portion of the new window that fits into the wall opening should be slightly smaller than the hole. Typically, a clearance of about 1/8 inch between the window frame and the wall is standard.

Shim Requirements:

Determine if you will need shims to centre the window in the opening. Shims are used to ensure the window is properly centred and secured in the opening.

By following these steps and taking precise measurements, you'll be well on your way to successfully replacing the windows on your Crestliner boat. Remember to take your time, double-check your work, and don't hesitate to seek assistance from a marine professional if needed.

Fitting the new windows

Step 1: Dry Fit the New Window

Insert the new window into the exposed opening to verify the fit. This process is easier with two people. Ensure that the exterior window flange overlaps the opening sufficiently to create a good seal. Determine if shims are required to centre the window. Then, remove the window to prepare for permanent installation.

Step 2: Prepare the Window for Installation

Place the window face down on a soft surface. Apply seal tape to the flange, starting in the middle of the window bottom and overlapping the ends by approximately half an inch. Pull off the backing from the tape. If you don't want tape sticking to the outer wall of the boat, use a spray water bottle to mist the perimeter of the opening.

Step 3: Install the Window

With the help of another person, insert the window into the opening. Centre the clamp ring on the inside of the window and install the screws provided with the window. Do not use longer screws as they can puncture the window frame and cause leaks.

Step 4: Install the Screen

Finally, install the screen by inserting it into the screen track. Push and pivot it into place, completing the installation.

Applying seal tape

Preparing the Window for Seal Tape Application:

Before applying the seal tape, it is essential to prepare the window properly. Place the new window on a flat and soft surface, with the exterior side facing up. This will ensure that the window is stable and protected from any scratches or damage during the tape application process.

Applying the Seal Tape:

• Start by positioning the seal tape on the flange of the window. The flange is the part of the window that will make contact with the boat's opening.
• Begin applying the tape at the middle of the window's bottom flange. This will ensure that the tape is centred and creates an even seal.
• As you unroll the tape, carefully smooth it out with your hands to avoid any air bubbles or creases. Overlap the two ends of the tape by approximately 1/2 inch. This will create a strong and watertight seal.
• Once the tape is in position, slowly and carefully peel off the backing from the tape. Take your time with this step to avoid accidentally pulling the tape off the window.

Misting the Opening:

To prevent the tape from sticking to the outside of the boat before you are ready, use a spray water bottle to lightly mist the perimeter of the opening. This will create a temporary barrier that will allow you to adjust the window's position as needed.

Inserting the Window:

With the seal tape in place, you are now ready to insert the window into the opening. This step is usually easier with two people. Carefully lift the window and position it into the opening, ensuring that the exterior window flange overlaps the opening sufficiently to create a good seal.

Securing the Window:

Once you are satisfied with the window's position, ask your assistant to hold it in place while you centre the clamp ring on the inside of the window. Use the screws provided with the window to secure the clamp ring in place. Do not overtighten the screws, as this may cause damage to the window frame.

Installing the Screen:

Finally, install the window screen by inserting it into the screen track. Push it up and pivot it into place, ensuring that it is securely fitted.

By following these steps, you will effectively apply the seal tape and install the new window on your Crestliner boat, creating a watertight and secure seal.

Installing the window screen

First, you will need to insert the window into the screen track. This may require some force, so be careful not to damage the window or the track. Once the window is in place, push and pivot it to ensure it is secure.

Next, you will need to attach the screen to the window. This can be done in a variety of ways, depending on the type of window and screen you are using. If you are using a clamp-style window, you will need to screw the screen into place. Make sure that the screws are tight and that the screen is secure.

If your window uses a different attachment method, such as a rubber set or an exterior surface mount, follow the appropriate instructions for attaching the screen.

Finally, test the window to ensure that it opens and closes smoothly and that the screen is secure. With that, your window replacement is complete!
