High Performance Aluminum Boat Propeller 11x15 Compatible with Tohatsu/Mercury Engine 35HP/40HP/50HP,13 Tooth,3 Blades,RH,(353B64107-0)

I. Installation Steps Pre-installation Check: Verify engine model and horsepower match propeller specifications. Inspect propeller blades for deformation or damage. Ensure mounting holes are clean and free of debris. Align Interface: Align the propeller keyway with the engine drive shaft key. Gently push onto the drive shaft, ensuring proper engagement. Secure Locking Mechanism: Install washers and nuts sequentially. Tighten using a torque wrench to specified torque. Apply a lock washer to prevent loosening during operation. Installation Verification: Manually rotate the propeller to confirm smooth rotation without binding or abnormal noise. Inspect the locking mechanism for secure fastening. II. Operation and Maintenance 1. Usage Precautions Strictly avoid high-speed navigation in shallow waters or reef areas to prevent blade impact with foreign objects. Ensure the propeller is fully submerged before engine startup to prevent dry-running damage. Match load to the engine's rated power to avoid overload operation. 2.Routine Maintenance After each voyage, rinse salt and sediment from the propeller surface with fresh water, then dry thoroughly before storage. Inspect blades for wear and corrosion every 3 months; replace immediately if cracks are found. For long-term storage, apply rust-preventive oil and store in a dry, well-ventilated area away from heavy loads.
