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

The Express® Mach4™ Right Hand Stainless Steel Propeller is engineered to deliver exceptional performance for a wide range of marine applications. With its innovative dual geometry design and superior TP17 stainless steel construction, this 4-blade propeller ensures enhanced acceleration, superior handling, and maximum durability.

Unmatched Dual Geometry Design

The Mach4™ propeller revolutionizes the market with its unique dual geometry blade design. Two blades feature a high-performance variable rake and aggressive pitch, providing incredible hole shot and superior cornering capabilities. The remaining two blades incorporate an offshore style design, ensuring high speed and maximum stern lift. This combination allows the Mach4™ to deliver remarkable handling and stability in rough waters without compromising top-end speed.

Superior TP17 Stainless Steel Construction

Crafted from proprietary TP17™ stainless steel, the Mach4™ propeller stands out in terms of strength and durability. With 20% higher chromium content than competitors, it offers increased shine and enhanced corrosion resistance. TP17™ stainless is nearly 250% stronger and five times more durable than standard stainless steel, allowing for more radical and high-performance designs that maximize your boat's capabilities.

Optimized Exhaust Flow

Equipped with large free-flowing exhaust ports, the Mach4™ propeller housing features pathways that offer 40% more exhaust flow area compared to competing products. This design reduces backpressure and can generate additional horsepower, similar to how headers operate on your boat, resulting in better overall performance.
