Turning Point Express Mach4 - Left Hand - Stainless Steel Propeller - EX-1513-4L - 4-Blade - 15.3" x 13 Pitch

The Express® Mach4™ Left Hand Stainless Steel Propeller is engineered for unparalleled performance and durability, making it the perfect upgrade for your marine vessel. Whether you're into watersports, navigating stern drive boats, or cruising tri-toons and bay boats, the Mach4™ delivers enhanced acceleration, superior handling, and maximum stern lift.

Unmatched Performance and Dual Geometry Design

The Mach4™ revolutionizes the propeller market with its unique dual geometry design, featuring two distinct blade shapes optimized for different performance aspects. Two blades incorporate a high-performance variable rake and aggressive pitch for exceptional hole shot and cornering capabilities, while the other two blades adopt an offshore style design for high-speed efficiency and maximum stern lift.

This innovative four-blade configuration ensures outstanding hole shot, superior handling, and exceptional stability in rough waters without sacrificing top-end speed, outperforming many competitors and even five-blade ski props.

Premium TP17™ Stainless Steel Construction

Crafted from proprietary TP17™ stainless steel, the Mach4™ offers superior strength and durability. With 20% higher chromium content than standard stainless steel, it provides enhanced shine and corrosion resistance. TP17™ stainless is nearly 250% stronger and five times more durable, allowing for radical design innovations that maximize your boat’s performance.

Enhanced Exhaust Flow for Increased Horsepower

The Mach4™ features large, free-flowing exhaust ports, offering 40% more exhaust flow area compared to competing propellers. This design reduces backpressure, enabling more horsepower to flow through your engine, much like a performance header system for your boat.
