YAMAHA 3HP Propeller Shaft

This YAMAHA 3HP Propeller Shaft is manufactured from high-strength alloy steel carefully selected to withstand continuous torsional loads, axial forces, and sudden impact stresses generated during marine operation. Precision CNC machining ensures accurate shaft diameter, spline profile, and bearing journal dimensions, allowing precise engagement with gears, clutch dog, and propeller hub. A controlled heat-treatment process is applied to enhance surface hardness while maintaining internal toughness, significantly improving resistance to wear, bending, and fatigue failure.

Designed as a direct replacement component, the YAMAHA 3HP Propeller Shaft meets OEM-level specifications for fitment and performance. It is compatible with Yamaha 3HP outboard motors commonly used on small fishing boats, inflatable boats, tenders, and lightweight recreational vessels. Whether replacing a worn, bent, or corroded original shaft, this propeller shaft helps restore smooth power transmission and stable propulsion output.

One of the key advantages of the YAMAHA 3HP Propeller Shaft is its durability in harsh marine environments. The material composition and surface finishing provide excellent resistance to corrosion and surface pitting, making it suitable for both freshwater and saltwater applications when proper lubrication and sealing are maintained. Accurate straightness control and balance reduce vibration during operation, minimizing noise and protecting related components such as bearings, gears, and oil seals from abnormal wear.

Each YAMAHA 3HP Propeller Shaft undergoes strict quality control procedures, including checks for straightness, spline accuracy, surface finish, and hardness consistency. These inspections ensure stable and repeatable quality for professional marine repair workshops, spare parts distributors, and aftermarket suppliers. As a cost-effective alternative to original parts, it offers dependable performance and long service life without compromising gearbox integrity.

The YAMAHA 3HP Propeller Shaft is an ideal solution for customers seeking reliable aftermarket transmission components that meet international quality standards. With precise fitment, strong load-bearing capacity, and excellent wear resistance, it helps reduce maintenance costs, improve repair efficiency, and extend the operational lifespan of Yamaha 3HP outboard motors.
