🔌 Function

The propeller converts engine torque into thrust. The 15-inch pitch Viper is an all-round performance option for boats requiring stronger acceleration than the 17-pitch version.

⚠️ 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
