Maxwell Seal Kit f/2200 & 3500 Series Windlass Gearboxes

The Maxwell Seal Kit for 2200 & 3500 Series Windlass Gearboxes is the maintenance essential every serious boater needs to keep their anchor winch running smoothly. Whether you're cruising coastal waters or dropping anchor in remote locations, your windlass gearbox endures constant exposure to salt spray, moisture, and mechanical stress. This seal kit addresses one of the most common points of failure in electric windlass systems—degraded seals that allow water ingress and salt corrosion into the gearbox housing. Replacing worn seals before catastrophic damage occurs is far more cost-effective than rebuilding or replacing an entire gearbox unit.

This Maxwell seal kit is engineered specifically for the 2200 and 3500 series windlass gearboxes, ensuring precise fitment and compatibility with your original equipment. The seals are designed to maintain a watertight barrier under the rotational and axial loads generated during normal anchor operations, preventing saltwater and debris from compromising lubrication and internal gear surfaces. Compact at just 0.15 lbs and measuring 3 x 1 x 5 inches, the kit contains all necessary replacement seals for a complete gearbox seal service. Preventive seal replacement is standard maintenance for any windlass system operating in marine environments, particularly after extended periods at sea or in brackish anchorages where salt accumulation accelerates seal degradation.

Boaters with Maxwell 2200 or 3500 series windlasses should perform seal kit replacement every 3–5 years, or immediately if you notice water seeping from the gearbox housing or hear grinding sounds during winch operation. Installation requires basic mechanical aptitude and access to the gearbox; many operators handle the service themselves during winter haul-out or routine maintenance cycles. Having this seal kit on hand ensures you're never stranded waiting for parts when seal failure occurs mid-season. Compatible exclusively with Maxwell's 2200 and 3500 series gearbox designs, this kit represents genuine OEM-quality sealing for reliable anchor deployment and retrieval in any condition.
