Turning Point Express Mach4 Stainless Steel Propeller – EX-1513-4 (15.3" x 13") – Right Hand, 4-Blade

Boost your boat’s performance with the Turning Point Express Mach4 EX-1513-4 Stainless Steel Propeller, designed for superior acceleration, handling, and durability. With a 15.3-inch diameter and 13-inch pitch, this 4-blade propeller delivers stronger hole shot, better mid-range power, and improved control compared to standard 3-blade props.

Crafted from high-strength stainless steel, the Mach4 prop provides excellent corrosion resistance and long-lasting performance in harsh marine conditions. Its advanced blade design enhances grip in the water, reduces slip, and minimizes vibration—giving you a smoother, more efficient ride whether you're cruising, towing, or carrying heavy loads.

Perfect for boaters who demand reliability and performance, this right-hand rotation propeller is compatible with a wide range of outboards and sterndrives when used with the correct Turning Point hub kit.

Key Features

• TP17™ Stainless Steel: Crafted from a proprietary stainless steel alloy that is stronger than standard steel, allowing for thinner, stiffer blades that reduce drag and increase efficiency.

• Aggressive Pitch & Cup: Features high-flow exhaust ports and aggressive cupping that provide superior grip and minimize cavitation, especially during tight turns or when pulling skiers and tubers.

• Speed & Handling: The 4-blade configuration offers more surface area than a 3-blade prop, resulting in faster acceleration (hole shot) and better low-speed planing without sacrificing significant top-end speed.

• Propeller Hub System: Designed for use with the Hub Kit (sold separately), which absorbs shift shock and protects your lower unit from impact damage.

• Size: 15.3" Diameter x 13" Pitch

• Blade Count: 4-Blade for better acceleration and stability

• Rotation: Right Hand (RH)

• Material: Premium Stainless Steel for durability and corrosion resistance

• Performance: Improved hole shot, mid-range power, and fuel efficiency

• Design: Reduced vibration and increased grip for smoother handling

• Compatibility: Fits multiple engines with Turning Point hub system

Installation Tip: This propeller requires a Turning Point Installation Hub Kit tailored to your specific engine brand and horsepower. Ensure you apply a liberal coat of marine-grade anti-seize grease to the propeller shaft splines before installation to prevent the prop from seizing over time.
