High-Performance Stainless Steel 4-Blade Outboard Propeller for Yamaha (13" × 19" Pitch)

Maximize your vessel's acceleration, rough-water grip, and high-speed efficiency with this High-Performance Stainless Steel 4-Blade Outboard Propeller for Yamaha (13" × 19"). Cast from premium marine-grade stainless steel, this 4-blade performance propeller offers superior rigidity and minimal blade flex compared to aluminum models—delivering exceptional stern lift, immediate hole-shot power, and durable impact resistance for mid-to-high-horsepower Yamaha outboard motors.

Key Features:

• Premium Marine-Grade Stainless Steel Construction: Cast from high-tensile, corrosion-resistant stainless steel that resists flex under high torque loading, maximizing engine horsepower transfer to the water.
• 4-Blade High-Thrust Geometry: Features four precision-cupped blades providing increased surface area for rapid hole-shot acceleration, improved stern lift, and unyielding bite in choppy water or tight turns.
• High-Speed 19" Blade Pitch: Engineered with an aggressive 19-inch pitch angle to optimize mid-range cruising speeds and top-end velocity on lighter, fast-planing hulls or higher-RPM Yamaha outboard applications.
• Superior Flex Resistance & Hydrodynamics: Thinner, stiffer blades reduce water drag and cavitation compared to standard aluminum propellers, resulting in better fuel economy and enhanced overall handling.
• Vibration-Dampening Rubber Cushion Hub: Equipped with an integrated rubber inner hub that absorbs lower-unit driveline shock during underwater strikes, protecting engine gears and driveshafts from costly damage.
• Direct Yamaha OEM-Spec Replacement: Manufactured to exact factory tolerances for a precise, drop-in fit on compatible splined Yamaha outboard motor shafts.

Why Choose a Stainless Steel 4-Blade Propeller?

If your boat suffers from slow hole-shot speeds, ventilation during hard banking turns, or excessive blade flex at top RPMs, upgrading to a 4-blade stainless steel propeller makes a dramatic difference. The rigid steel construction combined with 4-blade traction delivers maximum thrust, eliminates bow wander, and holds planing speeds at lower engine RPMs for a smoother, more efficient ride.
