Turning Point Propellers 3150 2131 Express Mach4 14x21 4-Blade Stainless Steel Propeller RH

The Turning Point Express® Mach4 propeller represents a breakthrough in marine propulsion technology, combining the aggressive hole shot and handling of a 4-blade design with the top-end speed typically reserved for 3-blade propellers. This 14-inch diameter by 21-inch pitch stainless steel propeller is engineered for outboard engines from 90-300+ horsepower with 4.75-inch gearcases, featuring right-hand (standard) rotation.

Dual Geometry Technology:

The innovative Dual Geometry blade design is what sets the Mach4 apart from conventional 4-blade propellers. This patented technology eliminates the traditional trade-off between acceleration and top speed, delivering exceptional performance across the entire RPM range.

Key Performance Features:

• Unprecedented hole shot acceleration with faster planning times
• Superior lift that raises the entire boat higher out of the water
• Enhanced handling and ease of steering in all conditions
• Exceptional stability and control in rough water
• Maintains 3-blade top-end speed without the typical 4-blade speed loss
• Reduced steering torque for less fatigue during extended operation

Construction and Materials:

Manufactured from premium stainless steel alloy using advanced casting technology, the Mach4 propeller offers superior strength and durability compared to aluminum alternatives. The high-gloss polished finish provides enhanced corrosion resistance for extended service life in both freshwater and saltwater environments.

Specifications:

• Diameter: 14 inches
• Pitch: 21 inches
• Blades: 4-blade Dual Geometry design
• Material: Stainless steel construction
• Rotation: Right-hand (standard rotation)
• Gearcase: Fits 4.75-inch gearcase housings
