2.1 Typical electrical layout

NOTE: This is not a wiring diagram.

1.Position the recommended circuit breaker close to the battery. See wiring diagrams Sec. 3.

2.Route 2 cables (see size table above) from battery to the control box.

3.Attach motor cables to control box (see wiring diagram) using recommended cable sizes.

4.Position the control box near the winch (±1 metre) in a dry area for watertight security and accessible for maintenance.

5.Position deck switches in view of winch. Route wire and attach to control box (see wiring diagram).

2.2 Main spindle rotation

Check correct main spindle rotation when fitted and operated.

34-77 specifications

The Lewmar 34-77 is a sophisticated and reliable winch designed for sailing enthusiasts seeking both performance and ease of use. This versatile winch is part of Lewmar's extensive range, known for its innovative engineering and high-quality materials. The 34-77 model combines strength, durability, and advanced features, catering to a variety of sailing conditions and user preferences.

One of the standout features of the Lewmar 34-77 is its self-tailing mechanism. This technology allows sailors to operate the winch without manual assistance in securing the line, providing ease of handling, especially when managing larger sails or when single-handed sailing. The self-tailing design features a robust, integrated clutch that securely holds the line while the winch is engaged, ensuring optimal performance without slipping.

The winch is constructed from high-grade materials, with a focus on maximizing corrosion resistance and longevity. The aluminum construction not only makes the winch lightweight but also provides exceptional strength, allowing it to handle heavy loads with ease. The hard-anodized surface treatment enhances protection against wear and abrasion, ensuring the winch can withstand the harsh marine environment.

Another characteristic that distinguishes the Lewmar 34-77 is its innovative gearing system. The winch features a 2-speed operation, allowing sailors to choose between higher speed for quick trimming and more power for heavy loads. This versatility enables a more tailored approach to sailing maneuvers, enhancing the overall sailing experience.

The design of the Lewmar 34-77 is also user-centric, incorporating a smooth and ergonomic drum. This feature minimizes friction, enabling easier line handling and increased efficiency. The winch’s low-profile design ensures that it doesn't obstruct movement on the deck, making it an ideal choice for both racing and cruising vessels.

In summary, the Lewmar 34-77 is a high-performance winch that embodies the essence of modern sailing technology. Its self-tailing mechanism, durable materials, efficient gearing, and user-friendly design make it a preferred choice among sailors who demand reliability and efficiency in their equipment. Whether you're racing competitively or enjoying a leisurely cruise, the Lewmar 34-77 ensures you have the tools necessary for a successful and enjoyable sailing experience.
