FAQ

  • Do I need 125HP to get good speed? No. For smaller boats, 9–18 HP with proper hull design and efficient propellers can provide strong performance for cruising and quick planning.
  • What is CDI ignition? CDI ignition is a capacitor-discharge system that provides reliable spark for quick starts and smooth operation.
  • Is a long shaft better? Long shafts suit boats with higher transom heights, improving propeller immersion and reducing cavitation.
  • Why is cooling important? Water cooling maintains engine temperatures, extending life and preventing overheating during prolonged use.
