Turning Point Express® Mach4™ - Left Hand - Stainless Steel Propeller - EX-1515-4L - 4-Blade - 15" x 15 Pitch

The Turning Point Express® Mach4™ Left Hand Stainless Steel Propeller (15" x 15 Pitch, 4-Blade) is engineered for boaters who demand precision control and dependable acceleration across varied water conditions. Whether you're navigating shallow flats, cruising open water, or tackling tight coastal channels, this left-hand rotation propeller delivers the responsive handling and fuel efficiency that serious anglers and recreational boaters rely on.

Built by Turning Point Propellers—a brand trusted for over three decades—this stainless steel design resists corrosion and maintains performance season after season. The 15-inch diameter with 15-pitch configuration strikes a balance between mid-range RPM operation and thrust, making it ideal for mid-sized outboards seeking smooth acceleration without excessive engine strain. The four-blade geometry provides superior grip in soft bottom and weed-prone environments while reducing slip compared to traditional three-blade designs.

Machined from marine-grade stainless steel, this propeller resists saltwater corrosion, pitting, and fatigue—critical for anyone operating in coastal or brackish waters. The left-hand rotation ensures compatibility with dual-engine setups or specific engine configurations, while the robust construction absorbs the stress of shallow-water operation and propeller contact. This propeller suits center console and cabin cruiser operators running mid-horsepower engines who balance speed and precision.
