High-Horsepower Aluminum Outboard Propeller (15 1/4" × 15" Pitch - 130HP+ / No Bush Kit)

Optimize your large vessel's hole-shot thrust, heavy-load displacement, and mid-range cruising power with this High-Horsepower Aluminum Outboard Propeller (15 1/4" × 15"). Precision-cast for high-output outboard engines rated from 130HP and up, this 3-blade universal propeller body delivers maximum hydrodynamic efficiency, smooth lower-unit torque transfer, and heavy-duty structural durability on open water.

Key Features:

• Heavy-Duty Marine Aluminum Construction: Cast from high-density, tensile-tested aluminum alloy engineered to handle heavy engine torque, high hydrodynamic pressure, and saltwater oxidation.
• High-Thrust 15 1/4" Diameter & 15" Pitch: The wide 15 1/4-inch diameter combined with a 15-inch pitch provides immense blade surface area, delivering exceptional stern lift, load-carrying stability, and quick hole-shot acceleration for larger hulls.
• Modular Interchangeable Hub Housing: Built with a universal hub cavity designed to accept heavy-duty interchangeable hub bush kits, adapting the propeller body to various major outboard manufacturer shaft splines.
• Cupped 3-Blade Hydrodynamic Profile: Computer-contoured blade cupping reduces cavitation, ventilation, and slip during tight turns and heavy-sea cruising.
• Multi-Layer Anti-Corrosion Finish: Coated in a tough, baked-on protective layer that resists paint peeling, pitting, and marine growth in both freshwater and marine environments.
• Cost-Effective Performance Replacement: Ideal as a high-performance primary prop or versatile spare, allowing boaters to utilize existing modular hub systems or install custom bush kits tailored to their specific gearcase.

Why Choose This Propeller?

Large, heavy-displacement boats powered by 130HP+ engines require high-thrust propeller geometry to push through heavy swells and carry substantial payloads efficiently. Replacing a damaged or underperforming prop with this wide-diameter 15-pitch propeller restores solid acceleration, lowers fuel burn at cruise RPMs, and eliminates gear-damaging vibration.
