Supplier's note

1. Three Technical Breakthroughs:

   • Material Strength (+30% in Pro Model): Enables handling of 90HP loads without deformation.
   • Corrosion Resistance (200 hours): Exceeds industry benchmarks by 100%, ideal for saltwater fisheries.
   • Precision Tolerance (±1%): Reduces engine misalignment risks in high-vibration scenarios.

2. Optimal Version Selection:

   • Base Model: Suitable for standard maintenance in freshwater lakes.
   • Advanced Model: Preferred by commercial fishermen needing durability in moderate saltwater.
   • Pro Model: Mandatory for offshore racing or industrial use where extreme loads and corrosion are critical.

With the Pro Model’s 845 MPa strength, you can achieve 20% faster acceleration than traditional crankshafts. Its MIL-STD-887 certification ensures reliability in extreme marine conditions.
