Important: Use well balanced propellers only. An unbalanced propeller causes vibration and loss of power.
The four-stroke engines were originally designed so that the propeller could be fixed to the engine with the usual nut, in order to prevent propeller slippage. However, if the propeller nut is inadequately tightened this can (due to detonation or „knocking „ if the engine is run too lean or under too heavy a load) cause the propeller to get loose and fly off. Obviously, this can be very dangerous. It is recommended to use the Safety Propeller Locknut Assembly supplied with the engine to prevent the propeller from fracturing or flying off, even if it loosens.
