PowerFlow 3B Propellers

Traditional power at its best!

compuflow-01For runabouts, small cruisers and fishing boats, Austral’s Power Flow is the standard by which other propellers are compared. The design has repeatedly proven superior in providing excellent all-round performance on a wide range of boats

The modern “skew back” cutaway blade shape allows the leading edges of the propeller to easily slice through the water. This combined with our modern precision methods of manufacture has ensured propellers of premium quality, accuracy and efficiency
