Lewmar V4/C4 Motor Gearbox - 24V

Power and Precision for Your Marine Anchoring System

Upgrade or replace the heart of your windlass with this robust 24V motor gearbox designed specifically for Lewmar's V4 and V5 windlass models, as well as the C4 and C5 capstans. Built to withstand the harsh marine environment, it delivers reliable torque and smooth operation, ensuring effortless anchor deployment and retrieval even in demanding conditions like strong currents or heavy loads.

Whether you're maintaining your existing setup or customizing a new installation, this gearbox integrates seamlessly, providing the power needed for chain and rope handling without compromising on safety or efficiency. Marine enthusiasts know that a dependable motor gearbox can make all the difference during those critical moments at sea.

Key Features That Stand Out

• High-Torque 24V Design: Optimized for low-speed, high-power applications, pulling up to demanding loads with consistent performance.
• Corrosion-Resistant Construction: Crafted from marine-grade materials that resist saltwater, UV exposure, and constant moisture for extended service life.
• Compact and Lightweight: Engineered to fit tight deck spaces without adding unnecessary weight to your vessel.
• Thermal Protection: Built-in safeguards prevent overheating during prolonged use, enhancing safety and longevity.
• Quiet Operation: Precision gearing minimizes noise, keeping your onboard experience peaceful even during anchoring maneuvers.

These features aren't just specs—they translate to real-world reliability that boaters trust for season after season.

Perfect Compatibility for Seamless Integration

This motor gearbox is a direct fit for Lewmar V4/V5 windlasses and C4/C5 capstans, making it an ideal spare or upgrade part. It's engineered to match the original specifications, so you avoid compatibility headaches. If you're retrofitting older units or building a custom setup, it pairs effortlessly with standard 24V DC systems found on most recreational and commercial vessels.

Pro tip: Always cross-check your windlass model's mounting pattern and voltage requirements to ensure a plug-and-play experience, saving you time and frustration during installation.

Benefits That Enhance Your Boating Experience

Investing in a quality motor gearbox like this one means fewer breakdowns and more time enjoying the water. It boosts your windlass's pulling power, reducing manual effort and strain on your crew. Over time, its durable build lowers maintenance costs and downtime, proving especially valuable for frequent cruisers or liveaboards facing variable sea states.

From weekend sailors to professional skippers, users report smoother chain management and quicker anchoring cycles, which can be a game-changer in crowded anchorages or poor holding bottoms.

Installation Insights from the Field

Swapping out a motor gearbox is straightforward for those with basic mechanical skills. Start by powering down your system and disconnecting the battery. Remove the old unit by loosening the mounting bolts and detaching the electrical leads—label them for easy reassembly. Align the new gearbox, secure it firmly, and reconnect everything following a logical sequence: ground first, then positive leads.

Common pitfalls to avoid include skipping a waterproof sealant around mounting points or neglecting to torque bolts to spec, which can lead to vibrations. Test under light load before full deployment to confirm smooth gypsy engagement. If you're new to this, consulting your vessel's wiring diagram ensures everything aligns perfectly.

Long-Term Maintenance for Peak Performance

Keep your gearbox running like new with simple routines: Rinse with fresh water after every saltwater outing to flush away corrosive residues. Inspect electrical connections seasonally for corrosion, and apply dielectric grease as a preventive measure. Listen for unusual noises during operation—they often signal early lubrication needs.

A quick annual service, including checking gear oil levels and brushing off any salt buildup, can extend its life significantly. This proactive approach minimizes wear and keeps your anchoring system ready for adventure.
