🔌 Function

The propeller converts engine torque into counter-clockwise thrust. In a twin installation, the opposite propeller rotations reduce steering torque and improve tracking, handling and manoeuvrability.

⚠️ Common Signs of Failure

• Blades are bent, chipped, cracked or out of track
• The rubber hub slips and engine RPM rises without matching boat speed
• Propeller vibration increases with engine speed
• Cavitation, ventilation or poor acceleration develops after impact damage
• Hub splines, thrust faces or retaining surfaces are worn or corroded
