Lewmar 34-77 manual Positioning winch ancillaries below deck, Fitting a convertible electric winch

Page 5

Use the template provided as a guide to position the winch on the deck.

NOTE: Check the scale of the template matches the winch (Fig 1.4.3).

NOTE: Make sure there is room below deck for motor and sub box.

1.5 Positioning winch ancillaries below deck

NOTE: The positioning of the motor gearbox must be checked prior to cutting for deck/hull and bulkhead clearance.

• The motor gearbox can be rotated in 90° steps, Fig. 1.5.1.

Fig. 1.5.1

• The motor rotation is factory set for fitting as Fig. 1.5.2.

Fig. 1.5.2

NOTE: The motor can be fitted as Fig. 1.5.3.

Contact Lewmar for correct fitting of electrical connections. If the motor is unitentionally fitted this way on a single speed winch it will not operate and make a clicking noise, on a 2 or 3 speed winch it will dramatically reduce performance.

Fig. 1.5.3

Check clearance below deck and accessibility then position the deck switches near and in view of the winch. Use the templates provided as a guide to cut/drill hole, fit switch and seal.

NOTE: Air switch tubing must be twist and chafe free to the switch unit (sub box).

DO NOT cover the air bleed hole with sealant as this will stop air escaping and could result in winches self operating as the air expands with rising temperatures in the tube.

Once you have selected the position for the winch, motor gearbox and controls, double check everything and only then drill the holes in the deck.

1.6 Fitting a convertible electric winch 34-65

NOTE: Illustrations are based on a model 50 winch.

Place the winch in position to ensure correct fit once the holes have been drilled/cut (Fig. 1.6.1).

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.
