Boat Trailer Polyurethane Bow Roller Assembly – Fits Multiple Brands (Replaces 3"x5" Non-Marking Rollers)

This polyurethane bow roller assembly is a durable, non-marking solution designed to protect your boat's hull during loading and trailering. It mounts directly onto your trailer's winch post, providing a smooth surface that prevents scratches and scuffs typically caused by traditional rubber rollers. The material is engineered to resist rust, corrosion, and developing flat spots, ensuring long-lasting performance.

It serves as a direct replacement for several common 3"x5" rollers, including Marine 3"x5" Bow Roller, GHmarine Boat Trailer 3" Polyurethane Roller, AnyLikely 3"x5" Polyurethane Assembly, and Sailor 3" Polyurethane Assembly.

• Material: High-quality, non-marking polyurethane for maximum hull protection.
• Dimensions: Features a 3" inner length, 5" outer length, and fits a standard 1/2" shaft.
• Complete Kit: Includes the bow roller, two end bells/caps, and mounting hardware for easy installation.

Installation Guide

1. Ensure the boat is securely positioned off the trailer's bow stop to relieve pressure.
2. Use a wrench to loosen and remove the nut from the existing bow roller bolt.
3. Slide the old bolt out of the winch post bracket to release the old roller. Note the order of any washers or hardware.
4. Clean the bracket area of any dirt or debris before installing the new roller.
5. Position the new polyurethane roller between the winch post brackets.
6. Slide the new 1/2" mounting bolt through the bracket, one end bell, the roller, the second end bell, and the other side of the bracket.
7. Securely fasten the nut onto the bolt.
8. Do not overtighten—the roller must be able to spin freely with minimal resistance.
9. Check for smooth rotation before loading the boat against the new roller.

Troubleshooting & FAQ

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

A: This roller is designed for trailer winch posts that accommodate a 3-inch wide inner roller and a 1/2-inch diameter shaft/bolt. The total outer length with end bells is 5 inches. Please measure your existing setup to confirm these dimensions before ordering.

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

A: Polyurethane is a far more durable material that is "non-marking," meaning it will not leave black scuffs or marks on your boat's hull. It is also resistant to rust, corrosion, and UV damage, and it will not develop flat spots over time like rubber can.

Q: Is a new bolt included with the roller?

A: Yes, this is a complete 3-piece assembly that includes the polyurethane roller, two end bells/caps, and a new 1/2" diameter mounting bolt with hardware.
