Turning Point 13.75x15 RH Mach3 Stainless Steel Propeller

The Turning Point Express Mach3 in 13.75-inch diameter and 15-inch pitch is a three-blade, right-hand stainless steel propeller. Its cupped blade profile and progressive pitch geometry are intended to help the boat accelerate cleanly and maintain grip through a turn. This is the EX1/EX2-1315 size, so it must not be confused with the smaller-diameter 19-pitch variation. For boaters coming from an aluminum prop, it provides a TP17 stainless alternative with a different blade design.

The Mach3 housing incorporates large exhaust passages intended to allow freer flow through the propeller hub. Turning Point uses its proprietary TP17 stainless formulation for corrosion resistance and durability. A 15-inch pitch may be appropriate when an engine needs less propeller load than a higher-pitch option, but the correct choice depends on wide-open-throttle RPM and the boat’s running weight. Performance differences are affected by hull shape, trim, engine height, and the existing propeller.

This housing uses the Turning Point interchangeable-hub arrangement and requires the correct engine-specific installation kit, sold separately. Check the EX1/EX2 propeller series and match the hub to the engine before ordering. Rotation must also agree with the drive, as a right-hand propeller is not a substitute for a left-hand model.
