Turning Point Express® Mach4™ - Right Hand - Stainless Steel Propeller - EX-1421-4 - 4-Blade - 14" x 21 Pitch

The Turning Point Express® Mach4™ right-hand stainless steel propeller (14" x 21 pitch, 4-blade) represents a generation of marine propeller engineering that transformed how performance-minded boaters approach thrust and handling. Designed for mid-range outboards and inboards, this propeller delivers the balanced combination of acceleration, fuel efficiency, and top-end performance that serious anglers and recreational boaters depend on for all-day runs to distant fishing grounds. The four-blade design reduces slip and vibration while maintaining the responsiveness needed in tight water and variable sea states.

Constructed from durable stainless steel, the Mach4™ resists corrosion in both saltwater and freshwater environments while offering superior strength compared to aluminum alternatives. The 14-inch diameter and 21-pitch geometry provide optimal blade loading for mid-sized powerheads, balancing hole-shot agility with sustainable cruising rpm. The four-blade configuration generates more bite per rotation, reducing cavitation and blade slippage—critical advantages when pulling loads or operating in choppy conditions. Stainless construction also means minimal maintenance and longer intervals between propeller service.

This right-hand propeller suits recreational boats, fishing platforms, and light-duty commercial vessels requiring reliable mid-range performance. Verify your engine's shaft diameter and rotation direction (clockwise or counterclockwise when viewed from behind) before purchase, as propeller fitment is platform-specific. Weighing 16.85 lbs, the Turning Point Express® Mach4™ is suitable for engines in the 150–250 hp range; consult your engine manufacturer's specifications to confirm compatibility. Installation requires basic hand tools and familiarity with propeller retention systems.
