Abstract

A wake adapted propeller drive mechanism delays or reduces cavitation or stall in a propeller drive mechanism mounted for rotation at the stem of a hull so as to be rotatable in a wake produced by forward motion of the hull through the water. The wake adapted propeller drive mechanism skews the drive shaft of the propeller sideways of the hull in a horizontal plane so as to adjust the angles of attack of the propeller to maintain the angles of attack below that which could produce cavitation or cavitation noise.
