A genuine Volvo Penta matched pair of Nibral folding propeller blades with a 14-inch nominal diameter, 8-inch pitch and right-hand rotation for shaft-drive only sailing installations.

• Engine / Drive Type: Volvo Penta sailing auxiliary engine with shaft-drive only folding-propeller installation

• Year Range: Approximately 1970s onward; final sizing is controlled by engine, reduction ratio and vessel data

🔌 Function

When the engine is engaged, centrifugal and hydrodynamic force open the blades to produce ahead or astern thrust. Under sail, the blades fold aft to reduce drag and improve sailing performance.

Common signs of failure or incorrect fitment:

• Blade bent, cracked, chipped or heavily eroded after impact

• Hinge bore, pivot pin or locking screw worn

• Blades do not open or fold evenly

• Vibration caused by unequal blade weight or damage

• Engine cannot reach rated RPM because pitch, diameter or rotation is incorrect
