Setup and Installation
This kit is intended for securing Lewmar Pro-Series 700/1000 and Pro-Fish 700/1000 Windlasses to the deck of a vessel. Refer to your specific windlass manual for detailed installation instructions, as this kit provides the fastening hardware.
- Preparation: Ensure the mounting surface on the deck is clean, flat, and structurally sound. Identify the correct mounting holes for your windlass model.
- Base Mat Placement: Position the base mat (gasket) between the windlass and the deck. This mat helps to seal the mounting area and reduce vibration. Align the holes in the base mat with the windlass and deck mounting holes.
- Insert Fasteners: Insert the metric threaded rods through the windlass base, the base mat, and the deck. Ensure they pass through cleanly.
- Secure with Washers and Nuts: From underneath the deck (or access point), place a washer onto each threaded rod, followed by a nut.
- Tighten: Hand-tighten all nuts initially. Then, using appropriate tools, gradually tighten each nut evenly to secure the windlass firmly to the deck. Avoid over-tightening, which can damage the deck or windlass base. Consult your windlass manual for specific torque specifications.

Operating Considerations
While this kit provides the fastening hardware, proper operation of your windlass relies on a secure installation. Regularly inspect the fastening points for any signs of loosening or corrosion.
- Ensure all nuts remain tight to prevent movement of the windlass during operation.
- Check for any water ingress around the mounting holes, which could indicate an issue with the base mat seal.
- Refer to your specific Lewmar windlass manual for operational guidelines, safety precautions, and maintenance schedules related to the windlass itself.
Maintenance
Regular inspection of the fastening kit components is crucial for long-term reliability.
- Visual Inspection: Periodically inspect the threaded rods, nuts, and washers for signs of corrosion, wear, or damage.
- Tightness Check: Annually, or more frequently in harsh marine environments, check the tightness of the nuts securing the windlass. Re-tighten if necessary, adhering to the windlass manufacturer's torque specifications.
- Base Mat Integrity: Inspect the base mat for cracks, tears, or signs of degradation. A compromised base mat can lead to water intrusion.
- Cleaning: Keep the area around the windlass base clean and free of debris, salt residue, and marine growth.
Troubleshooting
Issues related to the fastening kit are typically straightforward.
| Problem | Possible Cause | Solution |
|---|---|---|
| Windlass feels loose on deck | Nuts have loosened over time. | Re-tighten the nuts evenly. Consult windlass manual for torque. |
| Water leaking around windlass base | Damaged or improperly seated base mat; loose fasteners. | Check base mat for damage and replace if necessary. Ensure fasteners are tight. Apply marine sealant if required. |
| Corrosion on fasteners | Exposure to marine environment; lack of maintenance. | Clean affected areas. Apply corrosion inhibitor. Consider replacement if corrosion is severe. |
