A genuine used Yamaha Saltwater Series three-blade left-hand stainless-steel propeller for counter-rotation Yamaha large gearcases.

🔌 Function

The propeller produces counter-clockwise thrust from the port gearcase. Its 17-inch pitch supports strong planing and load carrying on heavier boats.

⚠️ 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
