Turning Point Express® Mach4™ - Left Hand - Stainless Steel Propeller - EX1/EX2-1319-4L - 4-Blade - 13" x 19 Pitch

The Turning Point Express® Mach4™ Left Hand Stainless Steel Propeller (13" x 19 Pitch, 4-Blade) is a precision-engineered marine propulsion component designed for high-performance recreational and professional vessels requiring reliable thrust and durability in saltwater and freshwater environments. Built for operators who demand consistent fuel efficiency and smooth acceleration, this left-hand rotating propeller integrates advanced blade geometry to reduce cavitation while delivering predictable handling characteristics. Whether for patrol boats, coastal operations, or demanding recreational applications, this propeller combines military-grade materials with proven marine engineering to ensure dependable performance in variable sea conditions.

Manufactured from marine-grade stainless steel, the Mach4™ propeller resists corrosion and saltwater degradation far more effectively than aluminum alternatives, extending service life and reducing maintenance cycles critical for high-use operations. The 13-inch diameter and 19-pitch specification optimize blade load distribution for engines in the mid-to-high horsepower range, while the four-blade design enhances stability and reduces vibration compared to three-blade configurations. Left-hand rotation ensures proper directional control when paired with compatible counter-rotating engine configurations, maintaining predictable steering response and reducing torque-induced drift during precision maneuvering. The 13.8-pound weight reflects the density and structural integrity required for saltwater durability without excessive drag penalty.

Operators managing twin-engine systems, patrol craft, or commercial marine platforms benefit most from this propeller's consistent performance envelope and minimal maintenance footprint. Installation requires verification of engine shaft specifications and rotation direction compatibility—left-hand props are critical for counter-clockwise rotating shafts to achieve proper thrust vectoring. This model is best suited for vessels operating in offshore or high-salinity environments where stainless steel's corrosion resistance justifies the investment. Always consult your engine manufacturer's propeller compatibility chart to confirm shaft diameter, taper, and keyway alignment before installation.
