The new Quad IV Plus, four blade stainless steel propellers is the big brother to the original Quad IV. The 16" diameter provides single and twin-engine sport boat owners the option to use higher "X" dimensions. The new shorter Bravo gear cases currently available are a perfect match to the Quad IV Plus. As with the 15 1/2" diameter Quad IV, these propellers are for boats with good natural bow lift, pad bottom boats, both single and double ventilated step bottom hulls, and air entrapment hulls. Kilo record top speeds are a trademark of the Quad IV Plus. These props are available in both right and counter rotation and in a pitch range of 28" – 34" in 1.0" increments. All propellers are furnished with the square bore design as standard. Quad IV Plus propellers are polished, balanced, heat treated, and utilize slightly thicker blades to enhance durability. Blueprinting/ Lab finishing is available at an extra charge for those of you that race and are looking for that last mile or two, but it will void the one year warranty. If you are looking for a propeller to provide you with excellent efficiency at both mid range and top end and are running a high "X" dimension, this is the propeller of choice.
