Turning Point Express Mach4 - Left Hand - Stainless Steel Propeller - EX-1515-4L - 4-Blade - 15" x 15 Pitch

The Express® Mach4™ Left Hand Stainless Steel Propeller EX-1515-4L is a high-performance 4-blade propeller designed for superior acceleration, handling, and load-carrying capabilities. Engineered with unique dual geometry blades, this 15" diameter by 15 pitch propeller delivers unmatched performance for a wide range of marine applications.

Revolutionary Dual Geometry Design

Turning Point’s Four Blade propeller revolutionized the marine propeller market with its innovative dual geometry blade design. This propeller features two blades with the Hustler high-performance variable rake and aggressive pitch for incredible hole shot and cornering performance, and two blades with an offshore style design for enhanced high speed and maximum stern lift. This combination ensures exceptional hole shot, improved handling, and superior rough water stability without sacrificing top-end speed.

Premium TP17 Stainless Steel Construction

Crafted from our proprietary TP17 stainless steel, the Express Mach4 series offers unmatched durability and performance. With 20% higher chromium content, this stainless steel provides superior shine and corrosion resistance. It is nearly 250% stronger and five times more durable than standard stainless steel, allowing for radical new designs that maximize your boat’s performance potential.

Enhanced Exhaust Flow

The Express Mach4 propeller features large, free-flowing exhaust ports in its housing, providing 40% more exhaust flow area compared to competitive products. This increased exhaust flow reduces backpressure, allowing for more horsepower to be generated—similar to the effect of headers on your boat.

Wide Compatibility

Compatible with a wide range of outboard and sterndrive engines, the Express Mach4 is designed to fit 9.9 (Bigfoot) to 300+hp Evinrude®, Force®, Honda®, Johnson®, Mariner®, Mercruiser®, Mercury®, Nissan®, OMC®, Parsun®, Suzuki®, Tohatsu®, Volvo® Penta®, and Yamaha® engines. To ensure a perfect fit, choose one of our Lifetime Warranty MasterGuard Installation Kits tailored to your specific engine model, then select the propeller that meets your boating needs.
