Turning Point Express® Mach3™ OS™ - Left Hand - Stainless Steel Propeller - OS-1613-L - 3-Blade - 15.625" x 13 Pitch

The Turning Point Express® Mach3™ OS™ - Left Hand - Stainless Steel Propeller is engineered for marine operators who demand reliable performance and fuel efficiency in demanding water conditions. This 15.625-inch, 3-blade left-hand propeller represents the evolution of Turning Point's proven VO series, delivering the next generation in propeller technology for serious boaters. Whether you're running a center console, open fishery, or cruising vessel, this stainless steel propeller provides the precision engineering needed to optimize your engine's potential and reduce fuel consumption across varying load conditions.

Constructed from marine-grade stainless steel, the Mach3 OS design features advanced blade geometry that minimizes slip and maximizes thrust transfer to the water. The 13-pitch configuration balances acceleration and top-end speed, making it ideal for mixed-use applications where neither raw power nor sustained cruising speed should be compromised. Stainless steel construction resists corrosion, reduces maintenance intervals, and maintains performance characteristics far longer than conventional aluminum alternatives, even in saltwater environments. The left-hand rotation specification ensures proper directional thrust and is critical for correct installation on port-side installations or specific engine configurations.

This propeller suits operators with mid-range horsepower engines seeking optimal mid-range performance without sacrificing low-end torque or high-speed capability. The 19.05-pound weight (16 x 8 x 16-inch package dimensions) is typical for 15-inch stainless steel props and ensures proper hub engagement and shaft integrity. Installation requires verification of left-hand rotation compatibility with your specific engine model and mounting hub; consult your engine documentation or a marine technician to confirm shaft diameter, key type, and thrust-bearing orientation before purchase. Regular inspection of the propeller for impact damage or blade erosion will maximize longevity and maintain fuel economy over extended seasons.
