4-Inch Yellow Polyurethane Bow Stop Roller – Fits Boat Trailers (Replaces 86287, 48651)

4-Inch Yellow Polyurethane Bow Stop Roller – Fits Boat Trailers

This bright yellow polyurethane bow stop roller is designed for a universal fit on boat trailers of various sizes. Its 4-inch width and 1/2-inch shaft hole provide a standard fit for most trailer bow stop brackets, offering a cushioned and highly visible contact point for your boat's bow.

The durable polyurethane material absorbs road shock, resists UV and water damage, and provides a soft, non-marking cushion between your boat's hull and the trailer hardware. This roller is a direct replacement for Tie Down 86287, Tie Down 48651, CE Smith 29301, and C.H. Yates 450Y.

• Durable polyurethane/TPR construction resists UV, saltwater, and freshwater damage.
• Features a standard 4-inch width with a 1/2-inch shaft hole for broad compatibility.
• High-visibility yellow color makes alignment easier during loading and launching.

Installation Guide

This roller typically mounts on the winch post to provide a resting point for the boat bow. Follow these general steps for replacement:

1. Ensure the trailer is on a level surface and the boat is safely secured or removed from the trailer.
2. Locate the bolt or shaft securing the existing bow roller. You may need to remove end bells or caps first.
3. Loosen and remove the mounting hardware, then slide the old, worn roller out of the bracket.
4. Clean the bracket area of any debris.
5. Position the new polyurethane roller into the bracket, ensuring the 1/2-inch shaft hole aligns perfectly.
6. Re-insert the shaft or bolt and securely fasten it with the original hardware.
7. Confirm the roller spins freely but is held firmly in place without excessive wobble.

Troubleshooting & FAQ

Q: How do I know if this roller will fit my trailer?

A: This bow stop roller features a universal design intended for most boat trailers. The key specifications to check are the 4-inch width and the 1/2-inch shaft diameter. Please measure your trailer's bow stop bracket and existing roller to ensure these dimensions match before purchasing.

Q: What is the benefit of polyurethane over a standard rubber roller?

A: Polyurethane is a modern, more resilient material compared to traditional black rubber. It offers superior resistance to UV sunlight, saltwater corrosion, and road shock. Most importantly, it is a non-marking material, meaning it will not leave scuffs, streaks, or black marks on your boat's hull.

Q: How often should I replace my bow stop roller?

A: We recommend inspecting your roller at the beginning of each boating season and periodically throughout the year. Look for signs of wear such as deep grooves, cracking, splitting, or deformation (flattening). Replace it as soon as you notice significant degradation to ensure your boat's bow remains fully protected.
