Discover the reliability and efficiency of the Lewmar Pro-Sport 550G horizontal windlass, crafted for boaters who demand smooth anchoring without the hassle. This 12V kit transforms how you handle rope and chain, blending robust construction with user-friendly operation. Whether you're anchoring in calm bays or facing choppy waters, its efficient spur gearbox and powerful permanent magnet motor deliver consistent performance on vessels up to 28 feet.

Why Choose the Pro-Sport 550G for Your Boat?

Boaters appreciate the Pro-Sport 550G for its balance of power, durability, and simplicity. The aluminum center case withstands harsh marine environments, while composite side covers resist corrosion and impacts. Low power draw means longer battery life during extended outings, and dual-direction operation lets you raise or lower your anchor effortlessly. Manual freefall adds a safety net for quick deployment, and the DIY-ready design suits weekend warriors tackling their own installs.

  • Exceptional Power-to-Size Ratio: Pulls up to 550 pounds at speeds reaching 98 feet per minute.
  • Versatile Compatibility: Handles 1/4-inch G4 or BBB chain, 6-7mm DIN 766, and 1/2-inch 3-strand or 8-plait rope.
  • Compact Footprint: Measures about 8-7/8 inches wide by 5-5/8 inches high, fitting neatly on most bow rollers.

Effortless Installation and Everyday Use

Above-deck mounting simplifies setup—no need for complex below-deck modifications. The kit includes everything for a straightforward install: base gasket for a watertight seal, fast mounting studs, installation wrench, circuit breaker, contactor, and guarded rocker switch. Connect to your 12V system, position on the bow, and you're ready to anchor with a simple push-button control. Pro tip: Align the gypsy precisely with your chain size to avoid jams and ensure smooth retrieval every time.

For maintenance, rinse with fresh water after saltwater use, inspect the gearbox oil annually, and lubricate moving parts sparingly. This keeps it running like new season after season.
