Turning Point Propellers 31430930 Express Mach4 14x9 4-Blade Stainless Steel Propeller

The Turning Point Express Mach4 31430930 is a high-performance 4-blade stainless steel propeller designed for 40-150hp outboards and sterndrives with 4.25" gearcases. Featuring an advanced swept cleaver design, this 14-inch diameter, 9-pitch propeller delivers the aggressive hole shot and superior handling of a 4-blade prop while maintaining the top-end speed typically associated with 3-blade designs.

Key Features:

• 14" diameter x 9" pitch with right-hand rotation for optimal performance
• Manufactured from proprietary TP17™ stainless steel with 20% higher chromium content for superior corrosion resistance and shine
• Swept cleaver blade design provides unprecedented hole shot, lift, and rough water stability
• 4-blade configuration lifts hull higher out of water, maintaining speed under heavy loads
• Performance-tuned exhaust vents improve acceleration and deliver best-in-class reverse thrust (up to 46% more than comparable designs)
• Large free-flowing exhaust ports with 40% more flow area reduce backpressure and increase horsepower
• Enhanced cornering ability and ease of steering compared to traditional propeller designs
• TP17™ stainless steel is 250% stronger and 5x more durable than standard stainless steel
