Lewmar V4/C4 Motor Gearbox - 24V

The Lewmar V4/C4 Motor Gearbox – 24V is a purpose-built electric drive system engineered for marine windlass and capstan applications. Designed for boat owners and marine operators who demand reliable anchor handling and mooring control, this gearbox integrates seamlessly with Lewmar's V4, V5 windlass models and C4, C5 capstan systems. The 24-volt configuration makes it ideal for standard marine electrical systems found on cruising sailboats, sportfishing vessels, and commercial marine equipment where dependable power delivery is non-negotiable.

This motor gearbox combines electric motor efficiency with precision gear reduction to deliver consistent torque and speed control for anchor deployment and retrieval. The 24-volt design operates efficiently across typical marine charging systems, minimizing voltage drop over longer cable runs common in larger vessels. At 31.05 lbs and measuring 8 x 8 x 19 inches, the compact footprint allows installation in confined bow lockers or motor wells without sacrificing mechanical advantage. The sealed gearbox housing protects internal components from salt spray and moisture, essential for longevity in offshore and coastal environments where corrosion poses ongoing risk.

Fleet operators, marine technicians, and serious cruising sailors benefit most from this direct-fit gearbox, which eliminates the need for costly custom fabrication or system redesign. Installation requires verification of compatibility with your specific windlass or capstan model—confirm your equipment uses V4, V5, C4, or C5 series before ordering. Replacement or upgrade scenarios often arise after years of heavy use or when upgrading from older manual systems; this gearbox unit accepts standard 24-volt control inputs and interfaces with existing Lewmar electrical harnesses, streamlining the retrofit process.
