• Fits YAMAHA Outboard Motor Engines 20HP 25HP 30HP F25 F30 T20 T25 T30（20-30 HP）. Compatibility is identical to genuine parts, requiring no additional adjustments
• High-strength aluminum alloy: Offers sufficient impact resistance while maintaining lightweight properties, effectively reducing engine shaft system loads.Its strength adequately handles power outputs from 20-30 horsepower engines and general waterway operating conditions.
• High fuel efficiency: 3-bladed propeller delivers greater power output efficiency at medium to high RPMs, minimizing energy loss and significantly improving fuel economy, making it ideal for daily use.
• Engine Protection Mechanism: Aluminum alloy material undergoes controlled deformation upon unexpected underwater impact, helping to absorb shock energy. This prioritizes protection of the more valuable lower transmission system of the engine, thereby reducing repair costs
