Baeksan Aluminum Outboard Propeller (10 3/8" × 11" Pitch – 9.9–25HP)

Optimize your boat's acceleration, mid-range cruising efficiency, and overall throttle response with the Baeksan Aluminum Outboard Propeller (10 3/8" × 11"). Precision-engineered from high-tensile marine-grade aluminum alloy and designed specifically for mid-range 9.9HP to 25HP outboard motors, this 3-blade replacement propeller delivers excellent hydrodynamic thrust, smooth low-vibration operation, and reliable driveline protection.

Key Features:

• High-Strength Marine-Grade Aluminum: Precision-cast from heavy-duty aluminum alloy designed to withstand high engine torque, hydrodynamic drag, and saltwater corrosion.
• Versatile 11" Blade Pitch: Features an 11-inch pitch angle that provides an optimal balance of quick hole-shot acceleration, stable planing performance, and efficient mid-range cruising RPMs.
• Shock-Absorbing Rubber Cushion Hub: Equipped with an integrated, pressed-in rubber inner hub that dampens driveline shock during minor underwater strikes, protecting your lower-unit gears and driveshaft from severe damage.
• Hydrodynamic 3-Blade Contour: Computer-molded blade cupping and rake angles minimize cavitation, water drag, and slip for immediate throttle response.
• Multi-Layer Anti-Corrosion Coating: Sealed with a tough, baked-on protective finish that guards against metal pitting, rust, and marine growth in both freshwater and saltwater environments.
• Direct OEM-Spec Replacement: Manufactured to exact factory specifications for a seamless, drop-in replacement on compatible splined 9.9HP to 25HP outboard shafts.

Why Choose This Propeller?

Worn, nicked, or misaligned propeller blades disrupt water flow, causing power loss, increased fuel consumption, and harmful lower-unit vibrations. Replacing a compromised propeller with this precision-balanced Baeksan model restores original engine responsiveness, smooth running performance, and efficient power transfer on the water.
