🔌 Function

The propeller converts engine torque into forward thrust. Its 19-inch pitch provides a useful balance of acceleration and cruising speed, while stainless blades reduce flex under load.

⚠️ Common Signs of Failure

• Blades are bent, chipped, cracked or out of track
• The 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
