Engine & Propulsion

Powertrain Dynamics & Hydrodynamic Efficiency

The propulsion assembly demands zero tolerance for failure. Our Engine & Propulsion inventory focuses on maximizing the transfer of engine torque to water thrust while minimizing energy loss. We supply precision-machined components designed to withstand the extreme cyclic loading, thermal expansion, and galvanic potential inherent in marine powertrains.

Technical Specifications:

  • Cavitation Mitigation: Propellers and underwater gear engineered with advanced blade geometries to reduce pressure drops and prevent surface pitting.
  • Vibration Damping: High-durometer elastomer mounts and couplers isolate harmonic resonance, protecting the hull structure from engine fatigue.
  • Metallurgical Composition: Usage of Nibral (Nickel-Aluminum-Bronze) and Aquamet-grade Stainless Steel ensures superior yield strength against rotational stress.
