Installation Guide
- Ensure the boat is safely removed from the trailer and the trailer is secured on a level surface.
- Locate the keel roller to be replaced. Loosen and remove the nuts or retaining clips from the roller shaft.
- Slide the old keel roller off the 5/8 inch shaft, retaining any washers or spacers.
- Clean the shaft of any dirt or corrosion and inspect it for damage.
- Slide the new self-centering keel roller onto the shaft. Ensure it is oriented correctly to guide the keel.
- Re-install any original washers or spacers and securely tighten the nuts or retaining clips on the shaft ends.
- Verify the roller spins freely and is properly aligned on its bracket before loading the boat.
Troubleshooting & FAQ
Q: How do I confirm this roller fits my trailer?
A: Measure your trailer's current roller shaft diameter. This roller is designed specifically for a 5/8 inch diameter shaft. Also, confirm the 8-inch length fits your existing trailer bracket.
Q: Will this polyurethane roller damage my boat's hull?
A: No. The high-quality PU (Polyurethane) material is specifically designed to be non-marring and will not scratch, scuff, or damage your boat's gelcoat or painted finish.
Q: What is the benefit of a "self-centering" design?
A: The V-shape and built-in grooves on the roller automatically guide the boat's keel to the center of the trailer during loading. This makes loading easier, especially in wind or currents, and reduces strain on your equipment.
