SUZUKI PROPELLER NUT REC09141-12005

Function and technical context

The propeller nut is the fixing element that retains the propeller on the drive shaft of the outboard motor, ensuring that the propeller remains secured to the shaft during navigation. It works within the propulsion system and is subjected to torque, vibration and continuous exposure to salt or fresh water, which requires specific materials and geometry for each application. Poor tightening or a damaged nut can cause the propeller to loosen while running, with the risk of total loss of propulsion, damage to the shaft or even loss of the propeller. Suzuki part number 09141-12005 is the appropriate replacement part for the small and medium displacement Suzuki outboard motors indicated in the compatibility table.

When to replace this part?

The most common symptoms that indicate the need to change the propeller nut are: visibly corroded, deformed nut or with a damaged hexagon that prevents correct tightening with the socket wrench, presence of axial or rotational play in the propeller, or detection of advanced galvanic corrosion in the shaft area. It is recommended to inspect the nut at each seasonal maintenance and whenever the propeller is disassembled to check the bushing or cotter pin. Preventively replacing the nut when it shows signs of wear prevents unwanted downtime and protects the axle and hub from more costly damage.
