Baeksan Aluminum Outboard Propeller (9" × 9" Pitch – 15HP)

Optimize your boat's throttle response, acceleration, and cruising performance with the Baeksan Aluminum Outboard Propeller (9" × 9"). Precision-cast from high-tensile marine-grade aluminum alloy and engineered specifically for 15HP outboard engines, this 3-blade replacement propeller delivers outstanding hydrodynamic efficiency, smooth low-vibration thrust, and reliable driveline protection.

Key Features:

• High-Strength Marine-Grade Aluminum: Precision-molded from heavy-duty aluminum alloy designed to withstand saltwater corrosion, high engine torque, and material fatigue.
• Balanced 9" Diameter & 9" Pitch: Features a 1:1 diameter-to-pitch ratio engineered specifically for 15HP outboard motors, providing an ideal balance of quick hole-shot acceleration, stable cruising RPMs, and fuel-efficient operation.
• Shock-Absorbing Rubber Cushion Hub: Equipped with an integrated rubber inner hub that dampens driveline shock during minor underwater strikes, safeguarding your lower-unit gears and driveshaft from costly damage.
• Hydrodynamic 3-Blade Geometry: Computer-optimized blade contours reduce cavitation, water drag, and slippage for immediate throttle response and steady planing.
• Multi-Layer Anti-Corrosion Finish: Sealed with a tough, baked-on protective coating that guards against surface pitting, rust, and marine growth in harsh saltwater and freshwater conditions.
• Direct OEM-Spec Replacement: Manufactured to exact factory tolerances for a seamless, drop-in replacement on compatible splined 15HP outboard shafts.

Why Choose This Propeller?

A damaged, bent, or chipped propeller disrupts water flow, leading to lost top-end speed, increased fuel consumption, and harmful lower-unit vibrations. Upgrading or replacing with this precision-balanced Baeksan propeller restores original engine responsiveness, smooth propulsion, and efficient power transfer to the water.
