Unmatched mid-range acceleration and blistering top speeds are trademarks of the Quad IV in both the pleasure and race arenas. These propellers are available in both right-hand and left-hand rotation, and pitch ranges in every inch from 19″ to 35″.
At 15 1/2″ in diameter, these propellers perform quite well with high “X” dimensions and are currently manufactured with a built-in flare ring to improve hole-shot and mid-range cruise speed.
The higher pitches are also available, from 28″ to 34″, in 16″ diameter with slightly more blade area, allowing for extremely high “X” dimensions. Quad IV propellers are polished, balanced and more importantly, are all heat treated.
