  1. Function: The inner propeller shaft, also known as the drive shaft, transmits power from the engine to the propeller, enabling the boat to move forward or backward in the water.
  2. Design: It’s a cylindrical metal rod that connects the engine output shaft to the propeller hub. It’s designed to withstand high torque and rotational forces while transferring power efficiently.
  3. Material: Typically made of high-strength stainless steel or alloy, ensuring durability and resistance to corrosion in the harsh marine environment.
  4. Compatibility: The inner propeller shaft is designed to fit specific marine engines and propeller configurations, ensuring proper alignment and engagement for efficient power transmission.
  5. Installation: Installed within the propeller housing or gearcase, it’s connected to the engine output shaft at one end and the propeller hub at the other.
  6. Maintenance: Regular inspection and lubrication are essential to prevent corrosion and ensure smooth rotation. Any signs of wear or damage should be addressed promptly to prevent mechanical failures.
