Turning Point Propellers 31432330 Express Mach4 4-Blade Stainless Steel Propeller 13x23 RH

The Turning Point Express Mach4 31432330 is a high-performance 4-blade stainless steel propeller designed for outboard and sterndrive applications from 40-150 HP with 4.25" gearcases. Featuring a swept cleaver design in Turning Point's proprietary TP17™ stainless steel, this 13-inch diameter, 23-pitch right-hand rotation propeller delivers exceptional hole shot, handling, and rough water stability without sacrificing top-end speed.

Key Features:

• 13" diameter x 23" pitch, 4-blade swept cleaver design with right-hand rotation
• Proprietary TP17™ stainless steel construction—250% stronger than standard stainless with 20% higher chromium content for superior corrosion resistance
• Lifts the hull higher out of the water, maintaining top-end speed even when fully loaded with passengers and gear
• Unprecedented hole shot and acceleration compared to traditional 3-blade propellers
• Performance-tuned exhaust vents with 40% more exhaust flow area than competitive designs for reduced backpressure
• Enhanced cornering, steering ease, and rough water stability ideal for watersports, bay boats, tri-toons, and sterndrive vessels
• Up to 46% more reverse thrust than comparable propeller designs
• Fits Evinrude, Honda, Johnson, Mariner, Mercury, MerCruiser, Nissan, OMC, Parsun, Suzuki, Tohatsu, and Yamaha outboards and sterndrives
• Requires 500 series installation/hub kit (sold separately)

The Express Mach4 series combines cutting-edge swept cleaver blade geometry with advanced TP17 stainless steel casting technology to deliver performance that rivals or exceeds newer OEM designs from recent decades. This propeller is specifically engineered for applications demanding enhanced acceleration, load-carrying capability, and stern lift without the typical top-end speed loss associated with 4-blade designs.
