Description
Express Mach4 - Left Hand - Stainless Steel Propeller - EX-1513-4L - 4-Blade - 15.3" x 13 Pitch
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 70s, 80s, 90s, and 00s, and will outrun most newer props, including five blade ski props.
Proprietary Stainless Steel, TP17
Formulated to meet the exacting requirements of the New Express Mach3 and Mach4 designs. 20% higher chromium content than the competition - more shine, better corrosion resistance. Almost 250% Stronger and 5X more durable than run-of-the-mill stainless steel. This new material allows Turning Point's Engineers and Designers the freedom to produce radical new designs that will help you wring the most performance out of your boat.
Large Free Flowing Exhaust Ports
Turning Point's Propeller Housings have massive Exhaust flow pathways. Their Propellers have 40% more exhaust flow Area versus competitive product. More exhaust flow and less backpressure can generate more horsepower. Like headers for your boat.
