Oceanvolt ServoProp 25kW
The most powerful hydrogeneration on the market
Powerful yet safe 48V system
Provides 25 kW of propulsion power while maintaining a safe 48V operating voltage, offering a balance of high performance, safety, and simplified maintenance.
Optimized design
Combines a high-efficiency saildrive with the most powerful hydrogenerator available. 360-degree rotating propeller blades optimized for both propulsion and energy generation.
Innovative installation
Can be installed with the propeller facing forward or backward for improved efficiency. Compact, integrated design with built-in motor controller, propeller control, and liquid cooling. Minimal maintenance.
Advanced hydrogeneration
The built-in hydrogeneration allows yachts to recharge batteries while sailing, reducing reliance on shore power or generators. Generates up to 5 kW at 10 knots, making it the most efficient system on the market.
