Baeksan Universal Aluminum Outboard Propeller (12 3/4" × 21" Pitch - No Bush Kit)

Optimize your boat’s high-speed performance, top-end velocity, and fuel efficiency at cruising speeds with the Baeksan Universal Aluminum Outboard Propeller (12 3/4" × 21"). Precision-cast from high-tensile marine-grade aluminum alloy, this 3-blade universal propeller body is specifically engineered to deliver maximum speed, reduced hydrodynamic drag, and smooth power delivery for high-RPM outboard applications when paired with a compatible hub kit.

Key Features:

• High-Strength Marine-Grade Aluminum: Precision-molded from heavy-duty aluminum alloy engineered to withstand high torque, cavitation forces, and saltwater oxidation.
• High-Speed 21" Blade Pitch: Designed with an aggressive 21-inch pitch angle to maximize top-end speed and high-RPM fuel economy on lighter, fast-planing hulls or high-horsepower outboard setups.
• Universal Interchangeable Hub Housing: Features a modular hub cavity designed to accept drop-in/press-in interchangeable bush kits, allowing a single propeller body to adapt to multiple outboard manufacturers and shaft spline configurations.
• Hydrodynamic 3-Blade Geometry: Computer-contoured blade cupping and rake angles minimize water slip and drag, providing maximum forward thrust at high operating speeds.
• Multi-Layer Anti-Corrosion Finish: Protected by a tough, baked-on paint finish that guards against pitting, oxidation, and marine growth in both freshwater and saltwater environments.
• Cost-Effective Modular Replacement: Allows boaters to reuse existing interchangeable hub hardware or select a custom bush kit tailored to their specific gearcase model.

Why Choose This Propeller?

Universal propeller housings offer exceptional flexibility and value when fine-tuning your boat's performance or replacing a damaged unit. By pairing this high-pitch, precision-balanced 21" Baeksan propeller body with your choice of hub bush kit, you achieve maximum top-end speed, eliminate driveline vibration, and maintain optimal propulsion efficiency.
