Installation Notes
This roller mounts on the winch post's bow stop assembly and provides a resting point for the boat's bow after the boat is loaded onto the trailer. Installation requires a compatible 1/2-inch shaft or bolt and suitable washers, nuts, or end bells to secure the roller in the bracket. Depending on the trailer configuration and boat size, a bow stop assembly may use one or more rollers. This listing is for the roller only; mounting hardware and shaft are not included.
Troubleshooting & FAQ
How do I know if this bow roller will fit my trailer?
Measure the width of your current roller, the bracket spacing, and the diameter of the mounting bolt or shaft. This roller is 4 inches wide and has a 1/2-inch shaft hole. Because bracket dimensions vary, compare all measurements with your existing assembly before ordering.
What are the benefits of a polyurethane roller?
Polyurethane provides a cushioned contact surface and is commonly selected for its non-marking characteristics and resistance to routine outdoor and marine exposure. The bright yellow color also makes the roller easy to see during loading.
When should I replace my bow stop roller?
Inspect the roller regularly for deep grooves, cracks, splitting, pieces breaking away, flattening, or other deformation. Replace it when it no longer provides a smooth, supportive surface for the boat's bow.
What are the signs of a failing bow roller?
Common signs include visible cracks, missing material, a flattened contact area, excessive deformation, or marks appearing on the boat's hull after trailering. Sticking or unusual resistance during loading can also indicate wear or an installation problem.
Can this roller be used in saltwater?
It is suitable for compatible saltwater and freshwater boat-trailer applications. Rinse the roller and associated hardware with fresh water after saltwater use, and inspect the assembly regularly for wear or corrosion.
Do I need to buy anything else for installation?
Yes. This listing includes the roller only. Depending on your trailer assembly, you may need a compatible 1/2-inch shaft or bolt, nuts, washers, or end bells. Existing hardware may be reused only if it is correctly sized and remains in good condition.
Is this an OEM part?
This listing is for a replacement bow stop roller. The referenced Tie Down, CE Smith, and C.H. Yates numbers are provided as comparison references; verify dimensions and application details before purchase.
How should the roller be maintained?
Keep the roller clean, rinse away salt and debris after marine use, and inspect the roller and mounting hardware before towing. Replace worn or damaged components before using the trailer.
Safety & Important Information
- Verify the roller dimensions, shaft-hole size, bracket spacing, and reference part numbers against your original component before purchase.
- Confirm that the roller is securely retained by correctly sized hardware before loading or towing a boat.
- Do not tow with a cracked, split, severely worn, or improperly secured roller.
- Professional installation is recommended if the correct hardware or bracket configuration is uncertain.
