Discover the engineering excellence behind TSD surface drive systems and how our innovative technology delivers superior performance.
Surface drive propulsion represents a revolutionary advancement in marine propulsion technology. Unlike traditional submerged propellers, TSD surface drives operate with the propeller partially submerged, piercing the water surface. This unique design delivers exceptional performance characteristics: The propeller blade rises above the water surface during operation, creating a distinctive "surface piercing" effect. This reduces water resistance, eliminates cavitation entirely, and allows the propeller to maintain optimal efficiency across a wide speed range. The system uses advanced hydraulic steering and trim mechanisms to maintain perfect blade positioning, automatically adjusting to sea conditions and vessel speed. The result is a propulsion system that combines the speed advantages of jet drives with the efficiency and control of traditional propellers, while eliminating the cavitation noise and vibration associated with conventional systems.
15-30% speed advantage over traditional propulsion
Zero cavitation at any speed
Shallow draft operation (typically 1.2-1.5 meters)
Exceptional maneuverability and control
Minimal vibration and noise
Reduced fuel consumption
