Turning Point Express Mach4 - Left Hand - Stainless Steel Propeller - EX-1421-4L - 4-Blade - 14" x 21 Pitch

The Express® Mach4™ Left Hand Stainless Steel Propeller is engineered for exceptional performance in a wide range of marine applications. Featuring a unique dual geometry design with four blades, this 14" diameter propeller delivers enhanced acceleration, superior handling, and increased load-carrying capabilities, making it an ideal upgrade for your vessel.

Dual Geometry Design

The Express Mach4 series revolutionizes propeller performance with its innovative dual geometry blade design. Two blades incorporate the Hustler high-performance variable rake and aggressive pitch, offering incredible hole shot and cornering capabilities. The remaining two blades utilize an offshore style design, ensuring high speed and maximum stern lift. This combination provides unprecedented handling, rough water stability, and excellent acceleration without sacrificing top-end speed, setting it apart from traditional four-blade props.

Proprietary TP17™ Stainless Steel

Crafted from TP17™ stainless steel, the Express Mach4 propellers offer superior durability and corrosion resistance. With 20% higher chromium content compared to standard stainless steel, TP17™ ensures a brilliant shine and enhanced longevity. The material is almost 250% stronger and five times more durable, allowing for more radical designs that maximize your boat's performance.

Large Free Flowing Exhaust Ports

Equipped with expansive exhaust flow pathways, the Express Mach4 propellers feature 40% more exhaust flow area than competing products. This design minimizes backpressure, enhancing horsepower output and performance, akin to the benefits of high-performance headers for your boat.
