Turning Point Express® Mach3™ OS™ - Left Hand - Stainless Steel Propeller - OS-1623-L - 3-Blade - 15.6" x 23 Pitch

The Turning Point Express® Mach3™ OS™ Left Hand Stainless Steel Propeller (OS-1623-L) is a 3-blade marine propeller engineered for boats requiring higher-diameter designs and superior performance in demanding water conditions. This 15.6" x 23 pitch left-hand propeller combines advanced blade geometry with stainless steel construction to deliver the durability and efficiency serious boaters demand, whether running offshore or navigating shallow coastal waters.

The OS series represents an evolution of Turning Point's proven larger-diameter VO platform, featuring refined cup design, optimized leading and trailing edge profiles, and an aggressive progressive rake geometry that are core to the brand's engineering. The 15.6-inch diameter and 23-pitch combination positions this propeller for vessels requiring the balance between acceleration and top-end speed, while stainless steel construction resists saltwater corrosion and maintains blade integrity under high-RPM operation. The left-hand rotation makes this the correct choice for port-side applications or dual-propeller setups requiring counter-rotating pairs.

Weekend fishermen and serious offshore anglers alike will benefit from the predictable handling characteristics this diameter and pitch deliver. The three-blade design provides smooth thrust distribution and reduced vibration, critical for extended runs where comfort and fuel efficiency matter. Whether upgrading from a worn original equipment propeller or optimizing a new build, this model serves applications where propeller selection directly impacts both performance and operational cost.

Propeller selection depends on vessel weight, engine horsepower, and intended use profile. The 23-pitch specification means the propeller advances 23 inches per complete rotation under ideal conditions. Verify your engine's mounting pattern and rotation direction before ordering to ensure compatibility with your specific application.
