Introduction
The Tie Down 86164 Bunk Slicks are designed to enhance the ease of launching and loading boats on trailers. These durable slicks reduce friction between the boat hull and trailer bunk boards, allowing for smoother movement. This manual provides essential information for proper installation, operation, and maintenance to ensure optimal performance and longevity of your bunk slicks.

Setup and Installation
Proper installation of the bunk slicks is crucial for safe and effective operation. These slicks are designed for direct attachment to existing carpeted or bare wood bunk boards.
Tools Required:
- Drill
- Screwdriver (or drill bit compatible with provided screws)
- Measuring Tape
- Marker or Pencil
Installation Steps:
- Prepare Bunk Boards: Ensure your trailer's bunk boards are clean and free of debris. If installing over carpet, ensure the carpet is securely attached. For bare wood, consider sealing or painting the wood for extended life before installation.
- Position Slicks: Place the bunk slicks along the top surface of your trailer's bunk boards. They can be installed end-to-end or with a small gap (approximately 4 inches) between them. The ribbed side should face upwards, contacting the boat hull.
- Mark Pilot Holes: Using the pre-drilled holes on the slicks as guides, mark the corresponding positions on the bunk board with a marker or pencil.
- Drill Pilot Holes: Drill pilot holes into the bunk board at the marked positions. Ensure the pilot holes are slightly smaller than the screw diameter to provide a secure fit.
- Secure Slicks: Align each slick with its pilot holes and fasten it securely to the bunk board using the provided screws. Ensure all screws are tightened firmly but do not overtighten, which could strip the wood or damage the slick.
- Verify Installation: After all slicks are installed, check that they are firmly attached and evenly spaced.

Operating Instructions
Once installed, Tie Down Bunk Slicks significantly reduce friction, making boat launching and loading easier. However, this increased slipperiness requires careful handling.
Launching Your Boat:
- Safety First: Always ensure the boat is securely attached to the trailer with a winch strap and safety chain before backing into the water.
- Submerge Trailer: Back the trailer into the water until the bunk boards are sufficiently submerged. Due to the reduced friction, you may not need to back the trailer as deep as with traditional carpeted bunks.
- Release Boat: Once the trailer is positioned, release the safety chain and winch strap. The boat should slide off the bunks with minimal effort. Be prepared for the boat to slide quickly once released.
- Maintain Control: Keep a rope tied to the boat to maintain control as it slides off the trailer.
Loading Your Boat:
- Align Boat: Guide the boat onto the submerged trailer bunks. The slicks will help center the boat and reduce resistance.
- Winch On: Use the trailer winch to pull the boat fully onto the bunks. The reduced friction will make winching significantly easier.
- Secure Boat: Once the boat is fully loaded, reattach the winch strap and safety chain before pulling the trailer out of the water.

Maintenance
Tie Down Bunk Slicks are designed for durability and require minimal maintenance. Regular inspection and cleaning will ensure continued performance.
- Regular Cleaning: Periodically clean the slicks with fresh water to remove any dirt, sand, or marine growth that may accumulate. This helps maintain their low-friction properties.
- Inspect for Damage: Before each use, visually inspect the bunk slicks for any signs of wear, cracks, or damage. Ensure all mounting screws are tight and the slicks are securely fastened to the bunk boards.
- Check Bunk Boards: If installed over bare wood, regularly check the condition of the underlying bunk boards for rot or deterioration, as the slicks do not prevent water absorption by the wood itself.
Troubleshooting
- Boat Slides Off Too Easily: The primary function of bunk slicks is to reduce friction. Always keep the winch strap and safety chain attached until the trailer is properly positioned in the water and you are ready to launch. Maintain control of the boat with a rope.
- Screws Loosening: If screws become loose, re-tighten them. If the bunk board material (e.g., soft wood) is not holding the screws effectively, consider using longer screws or reinforcing the bunk board.
- Slicks Not Performing: Ensure the slicks are clean and free of debris. Verify they are installed with the ribbed side facing upwards.
