🔌 Function

The propeller converts engine power into thrust. A 19-inch pitch commonly provides an all-round balance between hole shot and cruising speed when matched to the boat's weight and gear ratio.

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, drive-pin surfaces or thrust faces are worn or corroded

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
