The Turning Point Express Mach3 OS Series represents the evolution of high-performance stainless steel propellers for serious boaters. This 15.6" diameter, 11" pitch, 3-blade propeller features right-hand rotation and fits 4.75" gearcase outboards from 150-300+hp, as well as Mercury Alpha One and Bravo One and Volvo Penta SX sterndrives.
Advanced Design Engineering:
Building on the proven VO series foundation, Turning Point engineers refined the cup design, leading and trailing edges, and incorporated aggressive progressive rake with optimized blade geometry. The result is a propeller that delivers excellent hole shot performance, impressive bow lift, and class-leading cornering characteristics. The large diameter three-blade design provides outstanding mid-range fuel economy, making it ideal for extended cruising and maximizing time on the water.
TP17 Proprietary Stainless Steel:
Constructed from Turning Point's exclusive TP17 stainless steel alloy, this propeller offers 20% higher chromium content than competitive products for superior corrosion resistance and brilliant shine. The material is nearly 250% stronger and 5 times more durable than conventional stainless steel, enabling radical design innovations that extract maximum performance from your boat.
Performance-Enhancing Features:
- Large free-flowing exhaust ports with 40% more exhaust flow area reduce backpressure
- Performance-tuned pitch, rake angles, and exhaust vents for all-around performance
- Perfectly matched to large horsepower bay boats, offshore center consoles, and high-performance pontoons/tri-toons
- Compatible with all major outboard and sterndrive manufacturers including Mercury, Yamaha, Honda, Suzuki, Evinrude, and more
- Requires 500-series installation/hub kit for engines under 200hp or 700-series kit for 200+hp applications
Whether you're seeking better acceleration, improved fuel efficiency, or superior handling, the Express Mach3 OS delivers professional-grade performance with the durability to handle demanding marine environments.
