The Turning Point Express EX1/EX2 Stainless Steel Right-Hand Propeller (31431530) is engineered to deliver superior performance, durability, and efficiency for a wide range of outboard and sterndrive applications. With a 13.5" diameter and 15" pitch, this 4-blade stainless steel propeller provides excellent acceleration, improved handling, and enhanced mid-range performance on the water.
Manufactured from high-strength stainless steel, the Express series propellers feature advanced blade geometry that increases thrust while reducing slip. The 4-blade design improves hole shot, enhances grip in rough water, and delivers smoother operation compared to traditional 3-blade propellers.
This propeller is designed to work with Turning Point’s interchangeable hub system, making it compatible with many major outboard and sterndrive engines including Mercury, Yamaha, Honda, Suzuki, Evinrude, Johnson, and MerCruiser when paired with the correct hub kit (sold separately).
Ideal for fishing boats, pontoons, runabouts, and performance boats, the Turning Point Express propeller delivers reliable power transfer and long-lasting marine performance.
Speed and Durability: Manufactured with a proprietary heat-treated stainless steel that allows for thinner, stiffer blades compared to aluminum. This translates to higher top-end speeds and better resistance to minor impacts.
4-Blade Performance: The 4-blade design provides maximum lift and hole shot, making it ideal for heavier boats, water sports like skiing and tubing, or vessels that struggle to get on plane quickly.
Tuned Exhaust Venting: Features high-performance vent holes in the hub that allow exhaust gases to "slip" the blades during initial acceleration, helping the engine reach its power band faster for an explosive start.
Hub System Versatility: Designed to be used with the Hubex Exchangeable Hub System (sold separately), allowing you to move the propeller to a different engine brand just by changing the hub kit.
Precision Geometry: Utilizes aggressive progressive pitch angles and high-rake blade designs to improve bow lift and reduce drag.
The Turning Point Express Mach4 is an excellent choice for boaters looking to upgrade their handling and acceleration without the extreme cost of custom racing props.
