A genuine used Mercury Vengeance three-blade right-hand stainless-steel propeller for Mercury, Mariner and compatible MerCruiser large 15-spline gearcases.

This early 14 x 19 propeller belongs to the Vengeance 19-pitch service family. Its durable stainless blades reduce flex compared with aluminium and provide efficient all-round acceleration and cruising on a correctly matched hull.

🔌 Function

The propeller converts engine torque into forward thrust. Its 19-inch pitch provides a common all-round balance of acceleration, cruising speed and engine RPM for suitable planing hulls.

⚠️ 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
