Turning Point 14.25x21 RH Mach3 Stainless Steel Propeller

The Turning Point Mach3 EX-1421 is a 14.25-inch-diameter stainless steel propeller with 21 inches of pitch. Its right-hand rotation and three-blade configuration suit an appropriately matched outboard or sterndrive application. Turning Point combines a pronounced blade cup with progressive geometry to support grip at speed. Compared with smaller-pitch Mach3 options, this version places a greater load on the engine and should be chosen with RPM in mind.

TP17 stainless steel is used to form the cupped blades, and the propeller housing includes large exhaust outlets. Those details are intended to help the boat maintain controlled handling and allow exhaust to move through the hub. The high-pitch choice makes sense only when the engine can reach the recommended full-throttle range with its normal passenger and gear load. A boat that already struggles to accelerate may require less pitch instead.

This is the propeller housing for the EX-1421 configuration, not a complete engine-specific installation package. Choose the matching Turning Point hub separately and verify shaft, gearcase, and rotation requirements. Compare your present propeller dimensions before replacing it, particularly if a different model series is involved. Explore our stainless steel propellers range for additional pitch options.
