Installation Notes
- Ensure the trailer is on a level surface and the boat is securely supported off the trailer.
- Use a wrench to loosen and remove the nuts or bolts securing the old roller's bracket or shaft.
- Slide the old roller and shaft out of the mounting brackets. Note the order of any washers or spacers.
- Clean the bracket area to remove any debris or corrosion.
- Position the new roller, ensuring it aligns correctly with the keel path.
- Slide the new shaft through the bracket and roller, placing any new washers or hardware as required.
- Securely tighten the nuts or cotter pins to lock the shaft in place. Do not overtighten, as the roller should spin freely.
- Check roller alignment one last time before reloading the boat.
Troubleshooting & FAQ
How do I choose the right roller for my trailer?
Measure your existing roller's diameter and width, as well as the shaft diameter it mounts on. Use our "Available Models" table to match these specifications. Pay attention to the roller type (keel, wobble, bow stop) to ensure it fits its intended function.
What is the difference between PVC, Polyurethane, and Rubber rollers?
PVC is a hard, durable plastic resistant to cuts and abrasions, ideal for many boat types. Polyurethane (PU) offers excellent resistance to UV, oil, and gasoline, and is less likely to mark your hull. Rubber is a traditional, softer option that provides good grip but may wear faster.
What does a "wobble" roller do?
Wobble rollers are designed to move side-to-side, which helps to automatically center the boat on the trailer during retrieval. They are typically installed in sets along the trailer frame.
When should I replace my trailer rollers?
Inspect your rollers regularly. Replace them if you see significant cracks, flat spots, chunking, or if they no longer spin freely. Worn rollers can damage your boat's hull and make launching difficult.
Do these kits include all necessary mounting hardware?
Package contents vary. Assembly kits usually include brackets and basic hardware. Simpler roller-only models may not. Please refer to the "What's in the Box" section and product images to confirm what is included with the model you select.
How can I tell if a roller is failing?
Signs of a failing roller include visible cracks or missing pieces, a "flat" spot from being stationary under load for too long, and seizing or difficulty spinning. A noisy or grinding roller should be replaced immediately.
