Turning Point Express® Mach4™ - Left Hand - Stainless Steel Propeller - EX1/EX2-1423-4L - 4-Blade - 13" x 23 Pitch

The Turning Point Express® Mach4™ – Left Hand – Stainless Steel Propeller in 13" x 23 Pitch is engineered for serious boaters and anglers who demand reliable, consistent thrust across variable water conditions. This 4-blade left-hand rotation prop is built for high-performance vessels requiring balanced acceleration, fuel efficiency, and smooth operation at cruising speeds. Whether you're running offshore tournaments, navigating shallow flats, or simply logging reliable hours on family outings, this propeller delivers the predictable bite and response that separates quality equipment from the rest.

Turning Point's Mach4 line represents decades of marine propeller development, and stainless steel construction ensures superior corrosion resistance in saltwater, brackish, and freshwater environments alike. The 4-blade design increases grip and reduces prop slip compared to 3-blade alternatives, translating to better hole-shot characteristics and more stable plane-off behavior under acceleration. A 23-pitch specification means each blade revolution advances the vessel approximately 23 inches, making this configuration ideal for mid-range RPM applications where both top-end speed and mid-range torque matter. The left-hand rotation designation ensures compatibility with engines configured for counter-clockwise propeller rotation when viewed from behind the vessel.

This propeller is best suited for center console, open fishermen, and performance-oriented runabouts in the 18- to 32-foot range, particularly those powered by mid-to-high horsepower outboards or sterndrives. Before purchasing, verify your engine's rotation direction and hub compatibility—left-hand props are not interchangeable with right-hand models. Proper propeller selection hinges on matching pitch to your boat's weight, load capacity, engine displacement, and intended use; consult your engine manufacturer's guidance or a marine dealer if you're upgrading from an existing prop. Installation requires basic mechanical skill and the correct shaft hardware; always apply marine-grade grease to the hub during mounting to ensure long-term performance.
