Installation Guide
- Prepare the Trailer: Ensure the trailer is on a level surface and the boat is securely supported off the bow stop.
- Remove Old Roller: Loosen and remove the nuts and bolts securing the old bow roller shaft. Slide the shaft out and remove the old roller assembly.
- Position New Roller: Align the new 7" x 4" roller assembly with the mounting brackets on the trailer's bow stop post.
- Install Shaft: Slide the 1/2 inch shaft through the brackets and the center of the new roller.
- Secure Hardware: Fasten the washers and nuts onto both ends of the shaft. Tighten securely to ensure the roller is held firmly in place but can still turn freely.
- Final Check: Adjust the bow stop height as needed for your boat's hull and confirm all hardware is tight before loading your boat.
Troubleshooting & FAQ
Q: How do I confirm this roller fits my trailer?
A: This is a universal roller designed for boat trailers with a 1/2 inch mounting shaft. Measure your existing shaft or bracket to ensure compatibility. This assembly replaces 7" x 4" rollers from brands like GlückMarine, MARKGOO, and JFATXTT.
Q: What is the benefit of a polyurethane roller versus a rubber one?
A: Polyurethane (PU) rollers are known for being non-marking, which means they will not leave black scuffs or scratches on your boat's hull. They are also highly durable and resistant to UV degradation and saltwater.
Q: How can I tell if my current bow roller needs replacing?
A: Inspect your roller for signs of cracking, splitting, flat spots, or excessive wear. A worn-out roller will not spin freely and can make loading difficult or even damage your boat's hull.
Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.
Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
