Express® Mach4 Right Hand Stainless Steel Propeller - EX-1423-4 - 4-Blade - 14" x 23"
The Prop that put the "four" in Performance! Turning Point's Four Blade revolutionized the aluminum propeller market when introduced over 6 years ago. No one had ever produced an aluminum propeller with two different blade shapes (they call it Dual Geometry) for 90-300+hp applications. This prop is uniquely engineered with two blade geometries: two blades utilize the high performance variable rake and aggressive pitch design for incredible hole shot and cornering, and two blades utilize an offshore style design for high speed and maximum stern lift.
These props re-wrote the rules, proving that you can run a four blade that has unprecedented hole shot, handling, and rough water stability without the top-end speed loss you experience with other manufacturers’ propellers.
Now manufactured in the Industry leading TP17 stainless, the Mach4 series is perfect for any application that demands enhanced acceleration, cornering, and load carrying capabilities. This prop series is ideally suited for watersports, sterndrive boats, tri-toons, bay boats, and any vessel that can use stern lift. It is our best upgrade of older stainless designs from the 70’s, 80’s, 90’s, and ’00’s, and will outrun most newer props, including five blade ski props.
Note: A Hub Kit is required for installation of this propeller. See the Turning Point Selection Chart or the Prop Wizard™ for hub kit selection.
